Assembly instructions

The following steps provide an overview of how to assemble your RadRunner 3 Plus from Rad Power Bikes. If you’re reading a printed version of this manual, it may not be current. Please download the latest version of your manual, which may contain important safety updates, and view your ebike’s assembly video by going to rad-go.com/runner3.
Neither the assembly video, assembly steps, nor the rest of the manual cover all potential aspects of ebike configuration, maintenance, and repair, which can require specialized tools and skills. We recommend you consult a professional, reputable bike mechanic to assist in the assembly, repair, and maintenance of your RadRunner 3 Plus.

Tools you need before you start

Your RadRunner 3 Plus comes with many but not all of the tools you will need for assembly. In addition to the provided tools, you will need the following:

l Flat-side cutters. These are useful for snipping zip ties and much safer than tools like box cutters.

l Torque wrenches with Allen bits. For assembly and maintenance, you will need torque hardware across a range of torque values (0 to 60 Nm) to ensure your bike is safe to ride.
l 15 mm pedal wrench or crowfoot bit. Regular wrenches are too wide to fit between pedal and crank, and may make it impossible for you to properly secure your pedals without damaging them or your cranks. A 15 mm pedal wrench will fit properly, and an experienced mechanic can use such a tool to

What is “torque”? Torque is rotational force. In the bike industry, torque is typically measured in units of Newton meters (Nm). Applying the right amount of torque to your fasteners (bolts, nuts, etc.) is critical for your safety. To “torque” accurately, use a high-quality torque wrench. Torque wrench accuracy depends on your technique (e.g., wrench angle and grip location), so be sure to read the instructions that came with your torque wrench.

correctly tighten pedals to 35 Nm. If you do not have

that level of skill, you’ll need a crowfoot bit (shaped like the end of a pedal wrench) to use with your torque wrench

to secure your pedals to 35 Nm.

l Bicycle grease. Necessary to lubricate and/or prevent corrosion on certain parts.
l A clean shop towel or paper towel for cleaning excess grease.
l Bike pump with Schrader valve and pressure gauge. Properly inflated tires are a must for safety, comfort, and performance.
l A strong friend.
If you plan to do your own tune-ups, repairs, and other maintenance, please refer to “Tools and torque specifications” on page 12 for information on other tools needed for servicing certain components on your RadRunner 3 Plus. If you do not wish to acquire these tools for assembly and maintenance, we strongly recommend that you seek professional help to assemble and maintain your ebike.

Assembly steps
WARNING: Incorrect assembly, maintenance, or use of your
ebike can cause component or performance failure, loss of control, serious injury, or death. Ebikes have parts that non-motorized bikes do not have, and neither the assembly video, assembly steps, or the rest of the manual cover all potential aspects of ebike configuration, maintenance, and repair, which can require specialized tools and skills. We strongly recommend you consult a professional, reputable bike mechanic to assist in the assembly, repair, and maintenance of your RadRunner, or inspect your work if you choose to do it yourself.

1. Unpack the ebike. Open the bike box and, with the help of another person capable of safely lifting a heavy object, remove the ebike and place it upright on the back wheel and front fork protector plate. Carefully remove the packaging material protecting the bike frame and components. Keep the packaging materials in case you want to ship the bike later. Otherwise, recycle these materials, especially cardboard and foam, wherever possible. Carefully place the handlebar on the ground in front of the front fork. Remove the small box and carefully set out the contents. Ensure all of the following items are included with the ebike:

l Front wheel
l Front wheel quick release (in fork protector plate)

l Headlight l Assembly toolkit l Charger l Reflectors

l Pedals (left and right) l Keys (2) l Owner’s Manual l Rider Quick Reference

If anything is missing, please contact Rad Power Bikes.

l Handlebar stem faceplate and mounting hardware
l Front fender and mounting hardware

2. Install the center kickstand. Locate the center kickstand and mounting hardware to prepare for installation.

a. Remove the pre-installed bolts and washers from the center kickstand.

b. Move the split washers and flat washers against the bolt ends.

c. Orient the center kickstand so that the legs fold toward the rear of the bike

d. Position the center kickstand under the mounting bracket in front of the rear wheel so that the center block fits through the mounting bracket and the bolt holes are aligned.

WARNING: Be careful that the brake cable mounted on the chain-
stay does not get pinched between the kickstand and mounting bracket during installation, as this can result in rear brake failure leading to accidents, serious injury, or death.
e. Thread the bolts by hand through the mounting bracket, and then use an 8 mm Allen wrench to tighten the bolts until secure.

f. Use a torque wrench to torque the bolts to the value listed in “Tools and torque specifications” on page 12.

3. Orient the front fork properly. The brake caliper should be on the rider’s left side of the bike, and there should be no cables twisted around the head tube.

4. Install the handlebar.

a. Locate the handlebar stem faceplate and hardware.

b. Orient the handlebar properly. The brake levers should face forward and the throttle should be on the right side. Trace the brake housing from the left brake lever to the brake caliper and make sure the bundle of cables is not twisted.

Stem faceplate bolts

c. Center the handlebar on the stem. Place the

Handlebar roughly par-

handlebar into position on the stem so it’s

allel with headtube

centered. Your handlebar has the widest dia-

meter at its center. If it isn’t centered, it could

come loose. Tilt the handlebar so that it is roughly parallel with the headtube

when viewed from the side (see illustration).

d. Install the stem faceplate. Place the stem faceplate over the handlebar, and thread in the four bolts by hand. Then use an Allen wrench to tighten the bolts. Tighten each a little at a time, moving in an “X” pattern, to ensure they tighten evenly. Ensure the gap between the faceplate and stem is even.

Tighten bolts in an “X” pattern

–5–

e. Torque the bolts evenly. Move in an “X” pattern again, and use the torque value listed in “Tools and torque specifications” on page 12. If you decide to adjust the angle of the handlebar later (e.g., to bring it slightly closer to the seat), follow the same procedures listed here to ensure the handlebar is properly secured.
WARNING: Do not overtighten the stem faceplate bolts or stem clamp bolts beyond the torque
values listed in this manual, as this can result in component failure, which can lead to property damage, serious injury or death.
5. Install the front wheel onto the front fork as explained below.
WARNING: Do not touch the brake rotor, which has sharp edges and can
cause serious injury. Touching the brake rotor or brake pads with bare skin can also transfer natural oils. Oils or other lubricants can decrease braking performance. We recommend wearing protective gloves when working near the braking system.

FRONT WHEEL WITH QUICK-RELEASE MECHANISM
a. Locate and remove the quick-release skewer from the front fork protector plate. Open the lever, remove the thumbnut and cone spring on the opposite side, and remove the skewer. Keep the cam follower (see “E” in the illustration that follows) and the other cone spring in place on the lever side.

QUICK-RELEASE SKEWER

A Thumbnut (remove, set aside)
B Cone spring (remove, set aside)
C Quick-release skewer D Cone spring E Cam follower F Quick-release lever

NOTICE: The “Quick-release skewer” illustration shows you the components you need to retain. You can discard the packaging that protected your front fork while shipping. That packaging includes a plastic fork protector plate and a protective, hollow, metal rod that the skewer went through. Temporary, protective spacers may be on that hollow rod and their materials can vary, e.g., may be black plastic or look like thick metal washers. Do not put those spacers onto the quick-release skewer.
b. Install the skewer through the front wheel hub, starting from the side of the wheel without the brake rotor. Make sure to not touch the brake rotor. Reinstall the cone spring on the skewer. Ensure both cone springs point inward. Keep the lever open and thread on the thumbnut a couple of turns, leaving enough room for the fork dropouts.
c. Remove the hydraulic brake pad spacer from the brake caliper on the front wheel.
NOTICE: When the front wheel is not installed and the hydraulic brake pad spacer is absent, do NOT squeeze the brake levers. Doing so can cause the brake pads to clamp together too much and prevent the brake rotor from fitting between the pads. If this happens to you, install the brake pad spacer back between the pads to create more space between the brake pads for the brake rotor.
d. Have a friend hold the bike steady and fully upright until you have finished securing the quick-release lever. Do not prop the ebike on its kickstand.
e. Lift the front of the bike, removing it from the protective plate.

–6–

NOTICE: The front-fork packaging includes the fork protector plate as well as a metal spacer rod and, in some cases, smaller spacers that go around that rod. The smaller spacers may be black plastic, metal, or other materials, and may look like thick washers. You can recycle these packaging elements according to local rules. Just be sure to retain all of the components pictured in “Quick-release skewer” on the previous page.

f. Carefully lower the front fork onto the wheel. Pay attention to the brake rotor: It needs to slide between the brake pads. Once the rotor is between the brake pads, guide the fork onto the wheel so that the wheel axle enters the fork dropouts. (The fork dropouts are the slots on each end of the fork that the wheel axle fits into.)
g. Double-check that the wheel is fully inserted into the dropouts, that the wheel axle is level and parallel to the ground, and that the wheel is centered in the fork.

h. Make sure the quick-release lever is nestled into the curve of the cam follower, as in the top image in the “Cam follower position” illus-

trations.

i. Make sure your friend is still holding the bike fully upright and steady, which will ensure there’s even pressure on both sides of the

axle. This is critical for the next step.

j. Secure the quick-release lever.

FRONT WHEEL ASSEMBLY

Guide the brake rotor between the brake pads.
CAM FOLLOWER POSITION

NOTICE: The security and

stability of your front wheel depends on very tight clamp-

ing force from the quick

release lever. A properly adjusted quick-release lever

requires great force to close or open.

i. Open the quick-release lever all the way. Hold the

(1) quick-release lever (2) cam follower (3) thumbnut

thumbnut steady with one

hand while you spin the

quick-release lever clockwise with the other hand. Tighten the

lever as much as you can by hand.

The quick-release lever (1) must nestle into the curve of the cam follower (2) as shown in the top image. The lever should not be balanced on the widest part of the cam follower, as in the bottom image.

ii. At this point, the lever should be too tight for you to close it

halfway. Loosen it by a quarter spin and try to close the lever halfway again. Repeat untiil you can close the lever halfway.

iii. Make sure the lever is angled so that when you close it, it won’t hit any bike components like the fork or a

fender bracket, which could keep it from closing fully.

iv. Close the lever. This should be difficult and should leave an imprint in your hand. Fine-tuning the tightness of the lever can take several tries.

WARNING: If you cannot exert great force on the quick release lever to close it, you must seek

help from a professional bike mechanic. Failure to fully secure your front wheel can lead to serious

injury or death.

k. Inspect your front wheel installation: l Make sure the closed quick-release lever doesn’t touch any bike components such as the fork, which could
keep it from closing fully.

–7–

l Check that the same amount of dropout is visible under the axle on each side of the bike. (If there’s a difference, your axle is not fully inserted into both dropouts, and you’ll need to repeat the previous steps starting at the point where you check that both cone springs are pointing inward.)
l. Test your front wheel installation using these three tests: l With your friend holding the front wheel off the ground, spin the front wheel to ensure it has no wobble or looseness. l While straddling the bike with hands on the handlebars, squeeze the front-brake lever with your left hand. Rock the bike forward and backward. Ensure the front brake prevents the front wheel from spinning and that there’s no play or wiggle in the wheel, handlebar, or front fork. l Inspect the quick-release lever to ensure it has remained tightly closed.
m. Check the security of the rear wheel. You must also check the torque value of the rear wheel axle nut to ensure it’s correctly tightened (see “Tools and torque specifications” on page 12).
NOTICE: Inspect and test both wheels before each ride. Either wheel and other components can loosen over time and with the normal vibration of riding.
WARNING: An improperly secured front or rear wheel can cause loss of control, accidents, ser-
ious injury, or death. Check that the wheels are properly secured during assembly and before each ride.
6. Perform a handlebar twist and push test to ensure the front wheel and handlebar stem are securely connected. Instructions for doing so are in “Handlebar twist and push tests” on page 39.
7. Install the front fender and headlight. a. Locate the fender and mounting hardware.
b. Remove the headlight mounting hardware from the fork bridge.

c. Install the fender/headlight mounting hardware. Pass a bolt with a washer through the headlight mounting bracket and the fender bracket. On the other side of the fork, pass another washer over the bolt, and then thread the locknut on by hand. Torque the locknut according to the value listed in “Tools and torque specifications” on page 12.

d. Locate the fender mounting hardware. Pass a split washer and a flat washer over each bolt end.

e. Attach L-brackets. Thread in the bolt to attach the Lbracket to the mounting point on the back of the fork, as shown in the illustration, and tighten securely with a 4 mm Allen wrench. Repeat with the other L-bracket on the other fork arm.

Secure the fender mounting arms on the fork mounting points.

f. Secure the fender mounting arms. Place a fender arm eyelet over the L-bracket mounting point, and thread

in the bolt by hand. Secure the bolt with a 4 mm Allen wrench, as shown in the illustration. Repeat with the

other fender mounting arm.

g. Check that the fender and headlight are centered. The wheels should spin freely within the fenders without touching them. Once centered, torque the fender mounting arm bolts according to the value in “Tools and torque specifications” on page 12.

–8–

WARNING: A loose or improperly installed fender can interfere with the wheel or other moving
parts, creating a risk of component damage, serious injury, or death.

8. Plug in the headlight connector. Line up the internal notch and pins with the external arrows, and press directly together without twisting.

9. Adjust the headlight angle slightly downward so it won’t blind oncoming traffic. Using the tools listed in “Tools and torque specifications” on page 12, loosen the angle adjustment bolt and locknut, angle the headlight downward, and tighten securely. Do not overtighten.

which is marked “R,” should have

an “R” sticker attached, and has

a smooth pedal axle. The right pedal goes on the crank on the

drivetrain side of the bike, which

has the chain and is the same as

a rider’s right side when seated

on the bike.
b. Place a pea-size or slightly smaller amount of bicycle grease onto the threads of the right pedal.

a torque wrench with a crowfoot

bit for this task, but regular wrenches won’t fit in the narrow

space and may damage your

pedal or crank.

g. Torque each pedal to 35 Nm.

An experienced mechanic can

torque properly with a pedal

wrench, but if you’re less experienced, use a torque wrench with a crowfoot bit.

Right pedal: clockwise

Left pedal: counterclockwise

h. Wipe off any excess bicycle grease.

WARNING: Improperly or inadequately tightened pedals can fall off your bike while you’re riding,

leading to component damage, serious injury, or death. If you aren’t sure how to tighten your pedals or

don’t have appropriate tools, please get help from a professional mechanic.

11. Inflate the tires.

a. Inspect tires for damage. Check the tire side-

walls, beads and treads for any damage before

inflating. If you discover any damage, contact our product support team for assistance.

b. Ensure the tube is fully seated in the tires. If

you cannot squeeze the tire enough to check the tube position, deflate the tire further by remov-

ing the valve cap, and then press and hold the inner valve core to let some air out.
c. Check tube nesting within tires. Lift the wheel and squeeze the tire while gently rocking back and forth to ensure the tube is fully seated and not pinched anywhere between the tire and rim, and the tire bead is evenly seated within the rim. Repeat this process on the other side of each tire.

The bead is the hard, rounded end of the tire that goes into the wheel rim.

Visually inspect the sides of the tires, using the lines and markings on it as a reference to ensure the bead is inserted into the rim fully and evenly.

d. Inflate tires to recommended PSI. Use a floor pump with a Schrader valve and pressure gauge to inflate each tire to the recommended PSI (pounds per square inch) indicated on

the tire sidewall. Add a small amount of PSI at a time and verify that the tube is still nested within the tire properly and the tire bead is not out of alignment with the rim. Bounce the tire to help seat the tire bead more

evenly (if necessary). If you discover the tube getting pinched between the tire and rim at any point, deflate

the tire and start the process over again. Do not overinflate or underinflate tires. Once you’ve had a chance to ride your ebike you can adjust the PSI for your desired riding terrain and comfort level. For more information,

see “Tire and wheel care” on page 38.

12. Check the chain alignment. Stand at the right side of the bike and grab the right pedal. Rotate the right pedal and crank toward the back of the bike as though pedaling backward–this will run the chain through the drivetrain without spinning the wheels. Watch the chain and ensure the chain runs through the drivetrain (the freewheel, derailleur, and around the front chainring) smoothly. If the chain doesn’t run smoothly or something seems misaligned, please consult our online Help Center (radpowerbikes.com/help).

13. Check the bashguard position. The bashguard that helps protect your derailleur from impact damage must be positioned so that it does not touch or interfere with the operation of the derailleur. The derailleur must be able to move toward and away from the bike so that it can guide the chain on and off all of the gears on the freewheel. If the bashguard is too close to the bike, do the following:

— 10 —

a. Ensure that the axle nuts are torqued to the value listed in “Tools and torque specifications” on the next page.
b. Gently pull the bashguard away from the bike, by hand, so that the derailleur can operate correctly.
14. Activate your battery. Your battery has arrived in “ship mode,” which prevents power from deploying to the motor during shipping. To exit ship mode, press and hold the battery button for at least three seconds.

15. Prepare your ebike for use.

a. Complete all steps in “Adjusting for comfort and safety” on page 14, including checking that all hardware has been tightened according to the values in “Tools and torque specifications” on the next page.

Battery button

b. Perform the safety checks in “User maintenance instructions” on page 36 including the handlebar twist and push test in “Handlebar twist and push tests” on page 39.

c. Place the Rider Quick Reference card. If you’re assembling the ebike on behalf of the operator, be sure to use the supplied zip ties to attach the Rider Quick Reference card to the handlebars as shown in the illustration. If you are the operator, read the card and post it someplace for easy reference. We recommend hanging it with the Safety Check side facing out near wherever you prep your ebike before each ride.

d. Power on the ebike as described in “Start-up procedure” on page 28 and Ride Rad!

Attach the Rider Quick Reference card to the handlebar if you’re assembling the ebike for someone else.

Tools and torque specifications

Applying the right amount of torque to your ebike fasteners (bolts, nuts, etc.) is critical for your safety. Brake components must be torqued to the values listed here, unless a professional, reputable bike mechanic has inspected them and advised otherwise. Fasteners can loosen over time with normal usage, so it is important to periodically check these torque values.
To “torque” accurately, use a high-quality torque wrench. Torque wrench accuracy depends on your technique (e.g., wrench angle and grip location), so be sure to read the instructions that came with your torque wrench. The tool sizing listed below is a general guide, but it is possible that the head of a particular bolt on your ebike may vary, requiring a different tool (e.g., a 4 mm Allen wrench instead of a 5 mm Allen wrench). If so, use whatever tool fits the bolt head. Such differences will not affect the torque value for that piece of hardware.
If you are installing accessories from Rad Power Bikes, any necessary instructions, important safety information, and torque specifications will come with your accessory and/or be available online at radpowerbikes.com/help.
WARNING: Do not overtighten any bolts or fasteners beyond the values listed here, as this can result in
component failure, which can lead to property damage, serious injury or death.

Adjusting for comfort and safety

The following steps are critical for your comfort and safety, and must be performed before your first bike ride. We recommend that you consult a professional, reputable bike mechanic who specializes in bike fit.

Seat angle and horizontal position

Many riders prefer the seat to be roughly parallel to the ground, with its horizontal position in the middle of the range marked on the seat rails, which is good for those close to average height. To change the angle and horizontal position of the seat:

1. Loosen (but do not remove) the seat adjustment bolt. It’s located underneath the

seat and requires an Allen wrench, as shown in the illustration.

2. Move the seat backward or forward and tilt to adjust the angle. Do not exceed the limit markings etched into one of the seat rails, which show how far you can safely

move the seat forward and backward.

3. Ensure seat rail clamp is aligned correctly. The top of the clamp should be directly over the bottom of the clamp so that the seat adjustment bolt will clamp the seat rails properly.

Seat adjustment bolt, Allen wrench

4. Tighten the seat adjustment bolt securely to the torque value listed in “Tools and torque specifications” on page 12.

WARNING: A loose seat clamp or seat adjustment bolt can cause loss of control, ebike/property

damage, serious injury, or death. Prior to first use, be sure to torque the seat adjustment bolt according

to the specification in “Tools and torque specifications” on page 12. Regularly check that bolt and make

sure that the clamp on the underside of your seat is secure on the seat rails.

Seat height

An ideal seat height will allow you to be comfortable and get the best pedaling efficiency. When you are seated, you should be able to place the ball of your foot on the pedal at its lowest position while your leg is almost fully extended, with your knee slightly bent. The seat should never be so high that you need to rock side to side or fully straighten your legs while pedaling. Never pull out the seatpost so far that the minimum insertion point is visible above the seat tube (see illustration).

Seatpost out TOO FAR
The minimum insertion point on the seatpost must be inserted into the seat tube.

Depending on your preference, ability, and amount of experience with bike and ebike riding, you may find that lowering the seat so you can put one or both feet on the ground without dismounting may offer a safer and more comfortable experience.

Open the quick-release lever

Insert the seatpost, ensuring the minimum insertion point goes into the seat tube.

Close the quickrelease lever using your palm.

— 14 —

1. Open the seatpost quick-release lever.
2. Slide the seatpost in or out of the seat tube to a height appropriate for your leg length and preference. Do not extend the seatpost beyond the minimum insertion marking etched onto the seatpost (see the “Seatpost out TOO FAR” illustration).
3. Align the quick release clamp opening with the notch in the seat tube, and close the quick-release lever fully. Closing the lever should require enough pressure that it leaves an imprint in your hand. When closed, the seat should not move up, down, left, or right. If needed, adjust the lever tension by turning the adjustment nut opposite the quick-release lever.
WARNING: A loose seatpost can cause your seat to drop suddenly, which can lead to loss of control,
component damage, serious injury, or death. Regularly check to make sure that your seat’s quick-release lever is properly tightened.
4. Try out your seat fit, and repeat steps 1­3 if the seat position needs a bit more adjusting.
DANGER: Overextending the seatpost can cause it to break or fall off your ebike, which will put you at
very high risk of serious injury or death. Avoid this danger by inserting your seatpost into the seat tube far enough that the minimum insertion point is no longer visible.

Handlebar angle
Most riders will feel comfortable with the handlebar angled so that it is roughly parallel with the front fork, as shown in the more vertical position of the illustration. Once you have adjusted the seat to your leg length and preference, you may decide that you would like the handlebar to be angled slightly closer to the seat. If so, follow these steps.
1. Loosen the four stem faceplate bolts just enough to allow the handlebar to pivot, and position it as you prefer.
2. Re-tighten the stem faceplate bolts using the method described in the assembly instructions.
3. Test the positioning by sitting on the bike, making sure it’s comfortable and that the handlebar can turn freely without touching your body.
4. Inspect the stem faceplate bolts. Be sure the gap between the faceplate and stem at each bolt is even and torque all faceplate bolts according to the value listed in “Tools and torque specifications” on page 12.
5. Test the security of your handlebar by performing a handlebar twist and push test. See “Handlebar twist and push tests” on page 39.

Brake lever angle
The angle of the brake levers can be adjusted for the most comfortable hand position possible. For most riders, this will allow them to rest two or three fingers comfortably on the brake lever while keeping their wrists in a neutral position. To adjust the angle, follow these steps:
1. Loosen the brake lever clamp bolt using the appropriate Allen wrench. 2. Adjust the angle of the brake lever so it’s comfortable for the rider. 3. Retighten the brake lever clamp bolt according to the value listed in “Tools and torque specifications” on
page 12.

Brake lever reach
You can also adjust the brake lever reach (how close the brake levers are to the handlebar grips). For most riders, the default position of the brake levers will be comfortable. For others, especially those with small hands or sensitive joints, it may be more comfortable to move the brake levers closer to the handlebar. Here’s how:
1. Locate the brake lever reach adjustment screw behind the brake lever (see the illustration above).

Brake lever reach adjustment screw

— 15 —

2. Rotate the screw using an appropriate size Allen wrench. Rotate in a clockwise direction to move the lever further from the grip. Rotate counterclockwise to bring the brake lever closer to the grip. Be sure not to adjust the brake lever reach so close to the grips that the lever hits the grips when you apply your brakes.
DANGER: Always make your brake levers can’t touch the handlebar grip when you squeeze firmly. A
brake lever that can touch the grips may not engage the brakes fully, causing you to have difficulty slowing or stopping and putting you at very high risk of serious injury or death. Squeezing the brake lever halfway toward the handlebar grip must cause the brake pads to press firmly against the brake rotor. If you think your brakes may not be functioning properly, do not ride your ebike. Refer to our Help Center for more information (radpowerbikes.com/help).
TIP! Another way to maximize hand comfort is to angle your handlebar grips so that the wide section of the grip supports the outside part of your palm and keeps your wrists are in a neutral position while you have two or three fingers resting on each brake lever. You should be able to reposition the handlebar grips by applying firm pressure and twisting. If they don’t move, you can apply a small amount of rubbing alcohol between the grip and the handlebar as temporary lubrication:
1. Carefully insert a screwdriver between the handlebar tubing and the grip.
2. Pry the grip away from the handlebar slightly.
3. Use a paper towel or squeeze bottle to apply alcohol into the gap. This should help loosen the grip.
4. Twist your grip into the best position for your comfort, testing by trying the brake levers while seated.
5. Give the alcohol an hour to evaporate, and then test that your grips are secure before riding your ebike.

Rad UI Display and UI Remote angle

For best screen visibility and to prevent glare, angle the Rad UI Display and Rad UI Remote so that they don’t face you directly, but are tilted slightly away from you, when you’re seated and riding.

1. Loosen the Rad UI Display clamp bolts. Loosen just until the UI Display can rotate on the handlebar. Do not remove the bolts.

2. Rotate the Rad UI Display and test the positioning. The angle that will minimize glare and optimize visibility of the screen will depend on the rider’s height and biking position. Tilt away from the rider, but not so far that it’s horizontal. Test the position while seated on your bike outdoors, in sunlight. Adjust as desired.

Angle the Rad UI Display to minimize glare

3. Tighten the Rad UI Display clamp bolts. Tighten to the torque value listed in “Tools and torque specifications” on page 12.

4. Adjust the position of your Rad UI Remote. Follow steps 1-3 above, but apply them to the Rad UI Remote and its components.

Suspension fork
The suspension fork can move up and down to cushion bumps in the riding surface, which can make riding on a rough road or trail smoother and more comfortable. Depending on your weight or preference, you can adjust the preload (suspension fork spring compression).

Suspension fork

— 16 —

WARNING: A low preload setting (for a “softer” ride) can cause your fork to compress when you brake,
and the effect will be more dramatic for heavier riders, bikes with a lot of cargo (especially in front), and at higher speeds. If the fork compresses suddenly, that could cause loss of balance or a fall, resulting in serious injury or death. We recommend you start riding with a higher preload setting. If you want to try a lower preload, practice riding at that setting in a safe location (flat and free of hazards that might require sudden braking) and begin at low to moderate speeds. The suspension fork can also be locked out as a rigid fork, which will typically yield higher pedaling efficiency. To lock the suspension fork, turn the lockout lever, located on the suspension fork, counterclockwise. To unlock the suspension fork, turn the lever clockwise until it stops. To adjust the preload of the suspension fork, follow these steps: 1. Make sure the lockout lever is unlocked. 2. Turn the preload adjustment knob (located on the suspension fork and labeled “preload”). l To subtract preload (to make the suspension softer), turn the preload adjustment knob in the direction of the small “-” on the knob. A softer ride can be best for lighter riders or those who prefer maximum cushioning from bumps in the riding surface. l To add preload (to make the suspension stiffer), turn the preload adjustment knob in the direction of the small “+” on the knob. A stiffer ride can be better for heavier riders or those who prefer a stiffer, more efficient ride. For more information on adjusting suspension forks, please see our Help Center at radpowerbikes.com/help.
Ensure all hardware is tightened properly
Ensure all hardware is tightened properly according to the values in “Tools and torque specifications” on page 12. This is a critical safety step that you must not skip. If you do not own a torque wrench or you do not have the skills to check the tightness of your hardware, consult a local, professional, reputable bike mechanic for help. You can find more information about bike fit and making adjustments to your ebike in our Help Center at radpowerbikes.com/help.

Battery information

The battery that comes with your RadRunner 3 Plus is a state-of-the-art, lithium-ion battery that’s designed to give you years of power with proper care and use. Follow the recommendations here for the best possible performance.

Battery features
Please familiarize yourself with all of the components of your battery. When you are seated on your ebike, the charging port of your battery will be on the right side of the battery.
CAUTION: Do not put any object into your battery’s charging port other than the Rad Power Bikes charging plug designed for this purpose (and pictured in the illustration). Inserting other objects into the charging port could damage your battery.

Cbehracrgoivnegr pinorptlawcieth rub-
Charging port with rubber cover in place

Charging port, cover open, with charger output plug positioned for insertion

CHARGE LEVEL
On the top of your battery there is a button and 10 charge indicator LED lights. When you press the button, the LEDs will give you an approximation of your charge level: zero lights indicate zero or nearly zero charge, one light indicates about a 10% charge, two lights indicate about a 20% charge, and so on. When the battery is nearly empty, the first LED will blink.
NOTICE: If you press your battery button and none of the LEDs light up, it’s possible your battery is in ship mode. (If your battery is in ship mode, your bike will not power on when you press the power button on the Rad UI Remote.) To exit ship mode, press the battery button for at least three seconds.

You can also assess your battery’s charge level via the Rad UI Remote on your handlebar (see “Rad UI functions and electrical controls” on page 26 for more information). It’s possible for your battery’s indicator lights and your Rad UI Remote to report slightly different charge levels. That’s okay. If you notice a significant difference, this may indicate a problem in the electrical system. Please see “Troubleshooting” on page 40 for more information.

Safe operating temperatures

We recommend riding in temperatures between 5°F to 105°F (-15°C to 40°C). Colder or hotter temperatures increase risks to your health and can also cause harmful internal battery temperatures.

Riding in very hot temperatures: Know and respect your physical limits around exercising in hot temperatures, and consult your doctor if you have any concerns. To prevent

OPERATION: Recommended temperature range

damage to your battery, do not ride in temperatures above

105°F (40°C). If you choose to ride in extremely hot temperatures, use low levels of power assistance (low pedal assist

levels, low use of throttle) to keep the battery as cool as possible. This may lower the risk of the battery automatically

turning off to prevent use-caused heat damage.

— 18 —

DANGER: Do not ride in extremely hot temperatures. The more the ambient temperature exceeds
105°F (40°C), the greater your risk of exceeding a maximum internal battery temperature of 131°F (55°C). This can cause the battery to turn off as a safety precaution. Extreme heat may also cause critical failure of the battery up to or including an electrical fire. Factors that increase your risk for battery overheating include, but are not limited to, ambient temperatures above 105°F (40°C), direct sunlight for extended periods, high throttle usage, high PAS level, high payload, steeper inclines, and other environmental factors.
WARNING: Extreme cold of 5°F (-15°C) or below will reduce the range of your battery and can cause
the battery to shut off automatically to prevent damage. Do not depend on battery power to return you back to safety if riding near those extreme temperatures. Riding in freezing temperatures can also expose your ebike to de-icing salt, which can harm your ebike and electrical components or cause an electrical fire. See “Guard against rust, corrosion, and water damage” on page 40 for more information.

Removing and installing the battery
You can charge your battery either on or off your RadRunner 3 Plus. If you remove it for charging, storage, transportation, security, or some other reason, keep these procedures to prevent battery damage.

BATTERY REMOVAL To remove the battery, follow these steps.

1. Place the key into the keyport and turn it to the unlocked position.
2. The battery lock will release the battery from the frame and lift it out of the mount slightly.
3. Carefully lift the battery up, angling it away from and clearing the terminal contacts (“3” in the illustration).
4. Pull the battery out of the mount. Be careful not to drop or damage the battery when it’s loose from the bike. Do not touch or bend the terminal contacts.

Removing the battery

NOTICE: When the battery is off its mount, protect the battery terminal contacts from damage or exposure to harmful substances including liquids and salt. Do not touch the terminal contacts. If the terminals become damaged, please discontinue use and contact Rad Power Bikes Product Support immediately.

BATTERY INSTALLATION/MOUNTING
To install the battery, you do not need the key. Check to ensure the battery mount is clean and dry, and then follow these steps.

1. Gently insert the battery into the frame.
2. Align the battery with the terminal contacts.
3. Push down on the battery until you hear a click. Do not force the battery into the battery mount. Ensure the battery is locked in place by gently pulling upward on it.

Installing the battery

CAUTION: An unlocked or improperly attached battery can fall off a moving ebike, causing damage or injury. Always check that the battery is properly attached and locked to the frame before moving or riding your ebike.

Before you charge
NOTICE: Failure to follow the battery-charging best practices outlined in this manual could result in unnecessary wear to the battery and/or charger, and could lead to an underperforming or non-functional battery. Batteries damaged due to improper care will not be replaced under warranty.

Where to charge. Always charge in a safe, dry, indoor area that is away from children, direct sunlight, dirt, debris, tripping hazards (including electrical cords), or any materials that could ignite in the unlikely event of a charger or bat-

tery malfunction. Arrange the bike, battery, and charger to eliminate the potential for falls or other impacts. Make sure you stay close enough to it to check on it occasionally.
Turn the power off. Your bike must be turned off while the battery is charging.
Check the condition of your battery and charger. Make sure the battery, charger, and electrical cables show no signs of damage. The terminals on the battery and its mount must be free of dirt, rust, corrosion, and leakage.
WARNING: When charging any powerful battery, locate it somewhere you can get to it easily (or man-
euver past it to safety) should there be a fire. Do not place it in a hallway or near a door such that it could block your exit in an emergency.
WARNING: Letting a battery charge unattended increases the risk that a charging problem will go
undetected and lead to component damage or a fire hazard. Always charge your battery where you can monitor it.

Ensure the ambient temperature is appropriate. For

best charging performance and to minimize wear and tear

on components, we recommend charging at ambient tem-

peratures of 41°F to 77°F (5°C to 25°C). Your battery gen-

erates heat while charging, but it’s designed to air-cool, so

keep it uncovered with the light facing upward on a flat,

stable, hard, unheated surface. At relatively low tem-

peratures, charging can take longer.

CHARGING:

CAUTION: Do not charge your battery when it is

Recommended temperature range

warm from riding or in ambient temperatures

above 100°F (38°C) to prevent unnecessary wear and tear on battery and charger. If the battery has turned

off to prevent heat damage, wait until the battery cools down to turn the battery back on. Never charge your

battery on or near heat-generating devices.

WARNING: Charging your battery with a charger other than one supplied by Rad Power Bikes and
designed for your specific ebike model can cause damage to your ebike’s electrical system or create a safety
hazard. Only use a battery charger designed for your ebike and supplied by Rad Power Bikes.

WARNING: Using a damaged battery or charger can damage additional components or create a fire haz-
ard. Stop using your battery and charger and contact Rad Power Bikes immediately if any of the following
occur:

l Your charger’s flexible power cord or output cable or any of the electrical cables on your ebike is frayed, has broken insulation, or any other signs of damage,
l Your battery or charger is physically damaged, non-functional, or performing abnormally,
l Your battery or charger experienced a significant impact from a fall, crash, or shipping damage, with or without obvious signs of damage,
l Your battery is leaking a clear, pungent, gel-like substance (which is potentially corrosive and flammable),
l Your battery will not fully charge (not all of the LEDs will light up) after the battery has been charging long enough so that it should be fully charged, i.e., it’s been plugged in at least an hour longer than the time cited in “Estimated charging times” on page 22 and/or the LED or LEDs on the charger indicate it has finished charging.
l Your battery was submerged in liquid or had extensive water exposure or damage, or
l Your charger becomes too hot to touch (it’s designed to get warm with normal use), makes an unusual smell, makes a popping sound, or shows other signs of overheating.

Store any damaged or potentially damaged battery or charger in a safe, dry location away from the house and other flammable materials/structures and, as soon as possible, recycle or otherwise dispose of it according to local rules. Replacement batteries and chargers are available at radpowerbikes.com.

Estimated charging times
The time needed to fully charge your battery depends on its age, how far it was used to travel, the nature of that travel (terrain, payload, PAS and throttle use, etc.), and other factors. The table here provides a rough estimate of charge time based on distance traveled with moderate use of motor assistance. Charging at low temperatures can increase recharge time.
NOTICE: The battery may take longer to charge when fully depleted, when very new, and after 3­5 years of regular use. If your battery doesn’t seem to be charging normally, is taking longer to charge than expected, or you’re experiencing substantial reduction in range, discontinue use and contact Rad Power Bikes Product Support.

Distance 5 mi (8 km) 10 mi (16 km) 15 mi (24 km) 20 mi (32 km) 25 mi (40 km) 30 mi (48 km) 35 mi (56 km) 40 mi (64 km) 45 mi (72 km)

Recharge time .75 hour 1.5 hours 2.25 hours 3 hours 3.75 hours 4.5 hours 5.25 hours 6 hours 7 hours

Estimated range per full charge

We suggest that you select a lower PAS level when you’re getting to know your RadRunner 3 Plus and travel routes. Once you become familiar with your range requirements and the capabilities of your ebike, you can adjust your riding characteristics.

The table in this section provides range estimates to help you understand the factors that can increase or decrease range. Rad Power Bikes makes no claims about the range that individual users might experience in a particular situation.

25 mi (40 km):

l Hilly terrain l Windy

l Light pedaling l Heavy payload

l High pedal assist level, high throttle use

35 mi (56 km):

l Flat terrain l Not windy

l Light pedaling l Normal payload

l Low pedal assist level, minimal throttle use

45 mi (72 km):

l Flat terrain l Not windy

l Moderate to heavy pedaling
l Normal payload

l Low pedal assist level, minimal throttle use

Best practices for extending range and battery life
Follow the best practices listed below to help extend your range and battery life. l Whenever possible, avoid applying full throttle when the RadRunner 3 Plus has slowed to very low speeds, has
stalled, or stopped. l Pedal to assist the motor when climbing hills and accelerating from a stop. l Do not climb hills steeper than 15% in grade. l Avoid sudden starts and stops. l Accelerate slowly. l Avoid riding in extremely cold or hot temperatures.
Battery storage
When storing your ebike from Rad Power between rides, follow the recommendations below to maintain the health and longevity of your battery.

— 22 —

SHORT-TERM STORAGE TEMPERATURES
Store the battery in a dry, indoor location between 14°F to 77°F (-10°C to 25°C).
DANGER: Storing your battery above 131°F
(55°C), such as in a hot car in direct sunlight, can cause permanent range decline or critical failure, and could lead to electrical fire, serious injury, or death.

SHORT-TERM STORAGE: Recommended temperature range

LONG-TERM STORAGE TEMPERATURES
For long-term storage (more than two weeks), choose a dry, indoor location. The ideal minimum temperature for long-term storage is a bit warmer than what’s allowable for short-term storage. Make sure your battery stays between 40°F to 77°F (5°C to 25°C).

LONG-TERM STORAGE TIPS
l We recommend putting your battery in “ship” mode by pressing and holding the battery button for 3 seconds. This mode prevents the battery from releasing power to the electrical system, including any attached accessories. This can help extend its charge. To take your battery out of ship mode, press and hold the button again for 3 seconds.
l For long-term storage, we recommend that you keep your battery at approximately 40-70% charged. Check the battery’s charge level monthly. If necessary, use the charger from Rad Power Bikes to charge the battery to about 40-70% charged.
CAUTION: Long-term storage of your battery at temperatures above 95°F (35°C) or below 40°F (5°C) can reduce battery performance and lifespan.
CAUTION: Don’t store your battery long-term at full charge, zero charge, or very little charge. Storing your battery for long periods at full charge can cause range decline over time. Storing your battery for long periods at very little or no charge can cause permanent range decline or a non-functional battery.

Summary: Battery recommended temperatures
The temperatures listed below represent ambient temperatures. Internal battery temperatures are likely to be higher than ambient temperature during charging and use. The battery will automatically turn off to prevent damage when its internal temperature reaches below 5°F (-15°C) or above 131°F (55°C). Please see the preceding sections for more information.

Recommended operation (riding) range: 5°F to 105°F (-15°C to 40°C) Recommended charging range: 41°F to 77°F (5°C to 25°C) Recommended short-term storage range: 14°F to 77°F (-10°C to 25°C) Recommended long-term storage range: 40°F to 77°F (5°C to 25°C)

Additional critical battery safety information
You must read and understand all safety-related messages in this section before handling, using, charging, or storing the battery that came with your RadRunner 3 Plus.
l Always remove the key from the keyport of the battery before riding. Do NOT operate the ebike with the key in the keyport, or injury to your leg or damage to the electrical system can occur.
l Avoid salt water and de-icing compounds, which are very corrosive and can lead to damage, especially if they come in contact with the battery and its mount. Never ride through standing salt water, e.g., through waves at a beach.

— 23 —

DANGER: Never open the battery housing, which can expose you to caustic substances and electrical
shock. It can also create a fire hazard, which can lead to serious injury or death. Opening the battery housing may void the warranty.
WARNING: Never immerse or submerge the battery in water or liquid, including water in the battery
mount, which can cause damage, serious injury, or death. If the battery was immersed or submerged in water or another liquid, do not use the battery. CAUTION: Using aftermarket battery accessories or products that have not been tested by Rad Power Bikes for safety and compatibility may void your warranty, result in ebike or property damage, create a safety hazard, or cause injury. If you use products not tested and recommended by Rad Power Bikes, you do so at your own risk. CAUTION: To reduce the risk of fire, connect only to a circuit provided with 10 amperes maximum branch circuit overcurrent protection in accordance with the National Electrical Code, ANSI/NFPA 70. NOTICE: When the battery is off its mount, protect the battery terminal contacts from damage or exposure to harmful substances including liquids and salt. Do not touch the terminal contacts. If the terminals become damaged, please discontinue use and contact Rad Power Bikes Product Support immediately. NOTICE: Always follow any safety information attached to the battery or charger. A sample label for the battery that shipped with your ebike is shown at right, manufacturing location and other details may differ. Do not remove this label from the battery.

Operating instructions
WARNING: Incorrect assembly, maintenance, or use of your ebike can cause component or per-
formance failure, loss of control, serious injury, or death. Ebikes have parts that non-motorized bikes do not have, and neither the assembly video, assembly steps, or the rest of the manual cover all potential aspects of ebike configuration, maintenance, and repair, which can require specialized tools and skills. We strongly recommend you consult a professional, reputable bike mechanic to assist in the assembly, repair, and maintenance of your RadRunner 3 Plus, or inspect your work if you choose to do it yourself.
How the electrical system works
Your RadRunner 3 Plus is equipped with two ways for a rider to use power assistance from the motor forward: a pedal assist system (PAS) and a twist throttle.
WARNING: Practice using the pedal assist (PAS) and throttle in a flat, clear, open area until you under-
stand how these power sources work together. Failure to understand how to safely operate the PAS and throttle together can result in loss of control, crash, injury, and/or death.
HOW PEDAL ASSIST WORKS You can use the pedal assist system (PAS) to call up assistance from the motor while you are pedaling. Pedal assist uses a cadence sensor built into the drivetrain of the ebike. The cadence sensor detects when you revolve the pedals and signals the electric motor to provide the level of pedal assistance (0-5) that you selected.
HOW THE THROTTLE WORKS The throttle is located on the right side of the handlebar. Twist it to propel the ebike forward. The more you twist, the more powerfully the motor will propel you. Once you release the throttle or apply the hand brake, the throttle power will stop. You do not need to pedal to get power from the throttle. Some ebikes from Rad Power Bikes are equipped with an on/off switch for the throttle. These switches can be set to “off” even while the bike electrical system is on in order to prevent use of the throttle.
NOTICE: Throttle and motor use may not be allowed in all areas. It is your responsibility to know and follow local ebike regulations, rules, and traffic laws where you ride.

Brake light
The RadRunner 3 Plus is equipped with a taillight/brake light that is integrated into the electrical system. When you turn on your ebike, both the headlight and taillight will illuminate to make you more visible to other vehicles. Any time the ebike is powered on, squeezing one or both brake levers on the handlebar will activate the brake light, causing the taillight to illuminate additional areas.

Start-up procedure
Before you can take your first ride you need to have properly assembled your ebike, tightened all components correctly, read this entire manual, and had a professional, reputable bike mechanic check the assembly. You also need to be at least 16 years old, and don’t forget to put on a helmet.
Follow these steps to ride Rad!
1. Check that the battery is locked securely. Try tugging on the battery with the key removed; it should not move at all. If it does, push it down gently but firmly and try again until it latches.
CAUTION: Getting onto the ebike or riding it with the key in the battery can cause injury to your leg and damage to the key or lock mechanism. Always remove the key before riding the ebike.
2. Turn on the ebike. Locate the Rad UI Remote (near the left handlebar grip). Press the power button for about two seconds until the Rad UI Display and the Rad UI Remote turns on (the UI Remote will spell out “rAd”).
CAUTION: Do not confuse your keyport and the charging port. Do not insert your key into the charging port. Inserting anything into the charging port other than the charging plug can damage the battery.
3. Try out your bell if you haven’t already! It’s an important safety tool for alerting others to your presence, especially when passing. The bell is integrated into the left brake lever on your handlebar. To ring it, flick the bell lever; see the illustration “Handlebar features” on page 25.
4. Begin riding carefully. With the proper safety gear and rider knowledge, you may now operate your ebike. Start pedaling on flat ground, clear of obstacles and people, with the ebike in an easy (low) gear and at pedal assist level 0 or 1. You may also use the throttle to accelerate and maintain your desired speed.

— 28 —

NOTICE: While you’re getting to know your ebike, don’t ride with passengers or cargo (see “Carrying cargo or a passenger” on the next page for more information). Review, understand, and follow the safety information in “Ride as safely as possible” on page 43.
5. Use the throttle (next to the right handlebar grip) by slowly and carefully rotating it toward the rider. Do not use the throttle unless you’re on the bike, and note that the throttle can be activated with a twist any time the bike is powered on.
WARNING: Be careful not to accidentally twist the throttle, which can cause sudden acceleration. If
you’re not prepared for this acceleration, you can lose control of the ebike, which can lead to serious injury or death. To minimize this risk, always keep at least one hand ready to squeeze the brake lever to cut off power to the motor. When you dismount, power off the bike before moving it.
WARNING: Engaging the pedal assist feature, especially at a high setting, will cause acceleration that
may be greater than expected, especially for relatively new riders, and that can cause loss of control, serious injury, or death. To minimize risk, start at PAS level 0 or 1.
Moving and storage instructions
Please follow these tips to ensure your ebike is well cared for when you’re not using it.
PARKING AND STORAGE l Park in accordance with local rules and regulations, especially if you’re in a public place. l Park indoors whenever possible. If you must park outdoors in rain or wet conditions, do not do so for an extended
period of time, and afterward park in a dry location to allow the ebike systems to dry out. When any bike or ebike is exposed to wet conditions, it will need more frequent maintenance to prevent rust and corrosion and to ensure all systems work safely. See “Guard against rust, corrosion, and water damage” on page 40 . l Avoid parking or storing your ebike in direct sunlight, which can cause damage to electrical components. l Do not park or store your ebike in excessive heat, such as inside of a parked car on a hot day. Always store your ebike within this temperature range: 14°F to 77°F (-10°C to 25°C).
DANGER: Storing your battery above 131°F (55°C), such as in a hot car in direct sunlight, can cause
permanent range decline or critical failure, and could lead to electrical fire, serious injury, or death.
l Switch the power and any lights off to conserve battery power. Remove the key from the ebike and ensure the battery is locked to the frame or use the key to remove the battery and bring it with you for security.
l Register your ebike with BikeIndex, 529 Garage, or a regional bike registry (ask your local bike shop for recommendations) to increase the chance you’ll get your ebike back in the unfortunate event it’s stolen.
l Lock up your ebike to reduce risk of theft. You can purchase a lock from our website at radpowerbikes.com or consult a local bike shop.
TRANSPORTING l When pushing or carrying the ebike, turn off the power to avoid accidental acceleration from the motor, e.g. by
mistakenly twisting the throttle. l Do not leave a battery in direct sunlight or any location that is or may become excessively hot or cold, like a parked
car, for extended periods. l Before using public transportation (buses, trains, etc.) to transport your ebike, check with the relevant trans-
portation authority for rules that might apply to ebikes, including weight and size limits, tire widths, lithium-ion batteries, etc. l Avoid transporting any electrical bike on a vehicle rack or truck bed during rain, which may cause water damage to the electrical components. See “Guard against rust, corrosion, and water damage” on page 40 for more information. In any weather, it’s safest to remove your battery before transporting your ebike. Carry the battery inside the vehicle, carefully placed to protect it from impacts, dirt, liquids, or other hazards.

Carrying cargo or a passenger
Carrying cargo or a passenger can help you have more fun on your ebike and replace trips you’d otherwise make with a car, which we think is rad. It also involves additional risks. You must read and understand this entire chapter and the rest of the manual plus any documentation that comes with any accessories you purchase before you ride your ebike with cargo and/or a passenger.
WARNING: Cargo can only be safely carried on the built-in rear rack, or an optional front-mounted
rack, basket, or center console. Do not modify the built-in rear rack to accommodate third-party cargo accessories, as this will void your warranty and may result in accidents, property damage, injury or death.
WARNING: Do not attach a trailer to the built-in rear rack, as this may create unsafe riding conditions
leading to accidents, property damage, injury or death.
WARNING: The maximum recommended tire size for your RadRunner 3 Plus is 20″ x 4″. Tires that
exceed this diameter and width may not be compatible with your wheels, and may create unsafe riding conditions leading to accidents, property damage, injury or death.
Your RadRunner is designed to carry a passenger on its built-in rear rack if you add appropriate accessories. Depending on the weight, age, and other characteristics of the person you wish to carry, you may need an approved child seat or other accessories as explained in “Carrying passengers” on the next page.
WARNING: Do not allow a passenger to ride on the rear rack without appropriate accessories. Doing so
increases the risk of your passenger falling off the bike. It can also expose their body parts or clothing to the wheel, chain, or other moving parts, leading to serious injury or death.
For more information on optional accessories for your ebike, please go to radpowerbikes.com.
NOTICE: Carrying a passenger, child, or cargo may not be allowed in all areas. It is your responsibility to know and follow all applicable laws where you ride your ebike.
Weight limits
The total maximum weight limit (payload capacity) of your RadRunner 3 Plus, listed below, includes the weight of the operator as well as clothing, riding gear, cargo, accessories, etc. See “Carrying passengers” on the next page for more safety information about passengers. Total maximum payload of the RadRunner 3 Plus: 350 lb (159 kg) Rear rack maximum capacity: 120 lb (54 kg) The maximum payload capacity and other important safety information for specific Rad Power Bikes accessories will come with those products and/or be available online at radpowerbikes.com/help.
WARNING: Never exceed the payload limit of any accessory or component of your ebike even if you
attach to it an accessory that carries a higher weight limit. Overloading any component can cause component failure, loss of control, serious injury, or death.
WARNING: Failure to ensure that cargo can’t interfere with the operator’s control of the ebike can lead
to serious injury or death. The operator is always responsible for securing loads, loose straps, and gear.
Carrying loads (cargo) safely
Follow these instructions to maximize safety when using your RadRunner 3 Plus to carry cargo or a passenger.
LOAD AND SECURE CARGO CAREFULLY l Hold onto the ebike when loading and carrying cargo and/or passengers. The kickstand is not designed to be used
for loading cargo or passengers. Do not assume the bike is stable and balanced when using the kickstand. l Load cargo as low as possible and evenly on both sides of the rack to keep the ebike’s center of gravity low and
improve stability.
— 30 —

l Ensure cargo loads are properly secured and periodically check that nothing loosens, risks interfering with any moving parts, or risks touching or dragging on the ground.
l Ensure cargo loads do not obscure the headlight, taillight or reflectors when riding.
PRACTICE WITH LIGHT LOADS IN A SAFE AREA Carrying extra weight significantly affects braking, acceleration, turning, balancing, etc. These effects can be increased by challenging riding conditions, such as when roads are wet or slick. Hills that are normally easy to climb or descend without cargo can become challenging or even dangerous once extra weight is loaded onto the ebike.
Extra weight will also increase the time it takes to slow the ebike when braking.
WARNING: Carrying cargo significantly affects braking, acceleration, turning, and balancing, which can
increase the risk of falls and other accidents, potentially leading to property damage, serious injury, or death. To minimize such risk, practice riding with light cargo in a flat, open area before attempting to carry heavier cargo, especially on roads or hills and in wet conditions.
USE BOTH BRAKES With extra weight on your ebike, it’s more important than ever to use both front and rear brakes, and always engage the rear brake first to prevent excessive strain on the front wheel and fork and to prevent loss of control. Ensure both front and rear brakes are properly adjusted, maintained, and applied.
WARNING: Using the front brake by itself can cause excessive stress on components, damage to the
ebike and parts, loss of control, injury, or death. Always apply the rear brake before applying the front brake, using both brakes for all operations.
ADJUST YOUR ROUTES AND SPEED When carrying heavy loads, plan your routes to avoid challenging hills and other hazards. Ride more slowly, and leave more time and distance for braking.
Carrying passengers
Your RadRunner is designed to carry one operator (age 16 or older) and a maximum of one passenger. A passenger will require certain accessories in order to ride safely on the bike. What accessories they need (e.g., an approved child seat, the Passenger Package, etc.) will depend on their size, age, and other characteristics. When carrying passengers on your RadRunner, be sure to follow the recommendations in “Carrying loads (cargo) safely” on the previous page as well as the recommendations below. Ensure that the operator and any passenger are wearing a properly fitted and approved helmet.
l Always use the Passenger Package and any other passenger accessories required for the age, weight, and ability of the passenger you wish to carry. It is not safe for passengers to ride on the rear rack without appropriate accessories. Please refer to the accessory-specific information at radpowerbikes.com for the passenger accessories available for your RadRunner.
l When carrying a child, you must ensure that child meets the criteria for an approved child safety seat (the Thule Yepp Maxi child seat). Refer to the seat manufacturer’s instructions for more information on passenger criteria (www.thule.com). Otherwise, you must have the Passenger Package installed, including the wheel skirts, passenger foot pegs, and the passenger seat.
l To use the Passenger Package, a passenger must be tall enough to rest their feet on the passenger foot pegs, and they must be able to refrain from standing on those foot pegs, which have a payload capacity of 30 lb (14 kg) per side. Please refer to the safety guidelines online for the passenger accessories available for your RadRunner.
l Use fenders with the Passenger Package. A properly installed rear fender will help keep hands and feet clear of the spinning wheel.
l Do not allow anyone to stand or kneel on the rear rack or any other bike components. l A passenger should sit directly over or forward of the rear wheel, and no more than 40 lb (18 kg) should be loaded
over the rear 1/3 of the rear rack. l Do not allow anyone to sit sideways or backward on the rear rack.

User maintenance instructions

Follow these maintenance guidelines to ensure your RadRunner 3 Plus stays safe and fun to ride.

Check and service your ebike regularly
On any bike or ebike, certain parts need to be replaced periodically due to wear, and sometimes parts become damaged for various reasons. Check your ebike before each ride by following the directions in “Safety checklists” on page 33. Have your ebike regularly serviced by a professional, reputable bike mechanic. See “Recommended service intervals” below for more information.
Components of any electrical bike are subject to higher wear compared to the components of bikes without power assistance. This is because ebikes can travel at higher average speeds than regular bicycles and generally weigh more. Higher wear is not a defect in the product and is not subject to warranty. Typical components affected are the tires, brake pads and rotors, forks, spokes, wheels, and the battery.
If you need to replace a part on your ebike, visit radpowerbikes.com. If you want something that isn’t listed there, contact Rad Power Bikes Product Support. Be extremely careful about using parts or accessories that Rad Power Bikes has not tested for safety and compatibility with your specific product.
WARNING: Using aftermarket accessories or components (trailers, stands, vehicle racks, etc.) that have
not been tested by Rad Power Bikes for safety and compatibility with your specific ebike may void your warranty, create an unsafe riding condition, result in ebike/property damage, or cause serious injury or death. If you use replacement parts or accessories not tested and recommended by Rad Power Bikes, you do so at your own risk.

Recommended service intervals
Regular maintenance of any bike or ebike is key to ensuring the best possible performance and reducing wear and tear on systems. Ideal service intervals vary depending on use conditions. We generally recommend inspections, service, and necessary replacements be performed at the time and distance intervals described below, but have your ebike serviced more frequently if you ride aggressively, with heavy payloads, or in harsh conditions. Have your ebike inspected immediately if you notice problems or your ebike has been involved in a fall or other accident.
WARNING: Have your ebike inspected by a professional, reputable bike mechanic after any fall, crash,
or accident, as these can cause damage (visible or internal/not readily apparent), make your ebike unsafe, and lead to serious injury or death. Be particularly cautious about using a battery that has experienced a significant impact from a fall or crash; a damaged battery may not show external signs of damage. Using a damaged battery or charger can create additional ebike damage or a fire hazard. For more information, see “Battery information” on page 18.

AFTER BREAK-IN PERIOD OF 50­100 MILES (80­160 KM)

WARNING: Touching the brake rotor, which has sharp edges and can get
very hot while you’re riding, can cause serious injury, slicing damage, or burns. The brake rotor heats up from normal friction when the brake pads press against the brake rotor to slow or stop the ebike. Touching the brake rotor with bare skin can also transfer natural oils to the rotor, and oils or other lubricants can decrease braking performance. Do not touch the brake rotor, especially when it’s in motion or after you’ve been riding your ebike. Touch the brake rotor only for necessary maintenance when it is cool, not moving, and while you are wearing gloves or using other appropriate protective equipment.
Tire and wheel care
The tires and inner tubes that came with your ebike are designed for durability and safety for regular cycling activities. Wheels and tires need to be checked before each use to make sure they’re in good condition. Always replace tires and inner tubes that have punctures, cuts, bulges, damage, or excessive wear before you ride.
TIRE INFLATION Inflate tubes and tires to within the PSI (pounds per square inch) range stamped onto the tire sidewall. For additional information about tire pressure, please consult our Help Center at radpowerbikes.com/help.
NOTICE: Be sure not to confuse the PSI value on your tire sidewall with the “TPI” (threads per inch) value, which may also be listed there.
WARNING: Underinflating your tires can result in loss of control. Overinflating can make tires burst.
Either scenario can lead to serious injury or death. Always maintain the correct air pressure of your tires, which is listed on the tire’s sidewall, and use a regulated air source with pressure gauge so that you can measure pressure accurately.
WHEEL “TRUENESS” Your wheels must always spin straight (“true”) and must be repaired or replaced if they wobble side to side or up and down when spinning. To test them, do this:
1. Spin the wheel. 2. Brace a dull pencil against the frame or fork, with the tip just touching the rim.
If the gap between the spinning rim and pencil changes more than 5 mm, your wheels may need truing. If your wheels become untrue or if spokes loosen, which can happen with normal use, we recommend that you have a professional, reputable bike mechanic perform wheel tuning and truing operations. Do not attempt to true wheels or tighten spokes unless you have the highly specialized skills and tools to do so.
TIRE REPLACEMENT Even tires equipped with built-in flat-preventative tire liners, like those that come with your RadRunner 3 Plus, can and do get flats from punctures, pinches, impacts, and other causes. If you get a flat tire or see evidence of tire wear, you must replace your tire and/or tubes before operating the ebike again. Otherwise, you risk ebike damage, serious injury, or death.
CAUTION: Removing a tube from your wheel rim before the air has been released from it can cause the tube to burst, potentially causing serious injury. Always release air pressure before removing your tube.
WARNING: The maximum recommended tire size for your RadRunner 3 Plus is 20″ x 4″. Tires that
exceed this diameter and width may not be compatible with your wheels, and may create unsafe riding conditions leading to accidents, property damage, injury or death.
WARNING: Aftermarket tires or inner tubes not provided by Rad Power Bikes may not be compatible
with your wheels or the performance requirements of your ebike. Such tires can fail or create unsafe riding conditions, causing serious injury or death. Always use replacement tires and tubes that are sized to be compatible with your ebike frame. For safety, and if required by law, ensure replacement tires have sufficient reflective sidewall striping.

After replacing a tire or removing the wheel for any other reason, be sure to tighten your axles according to the values listed in “Tools and torque specifications” on page 12. For more information on tire or tube replacement, visit radpowerbikes.com/help .
Handlebar twist and push tests
WARNING: An improperly secured wheel and/or handlebar stem can cause loss of control, accidents,
serious injury, or death. Check that the front wheel and handlebar stem are properly secured during assembly and before each ride.
HANDLEBAR TWIST TEST 1. Get the ebike ready for testing. Turn off the ebike, remove the battery, and press and hold the power button to
discharge remaining power. 2. Brace the front wheel. Stand at the front of the ebike, facing the handlebar, and brace the front wheel between
your feet and lower legs. 3. Try to twist the handlebar. Hold both handlebar grips and push forward with one hand while pulling back with
the other. Push and pull at the same time with about 20 lb of force with each hand. 4. Ensure the handlebar and wheel stay properly aligned. The handlebar and handlebar stem must be tightly
secured, and the handlebar perpendicular to the front wheel. 5. Repeat the twist test pulling/pushing with the opposite hands, using about 20 lb of force pushing with one hand
and 20 lb of force pulling with the other hand. 6. Check for any movement or changes in alignment of the stem and handlebar relative to the front wheel. If
there was no alignment change, skip the next step, reinstall your battery, and test your ebike fully before riding. If you did not notice change in alignment, proceed to the next step. Be sure to tighten your bolts according to the values listed in “Tools and torque specifications” on page 12.
HANDLEBAR PUSH TEST This test will involve applying force directly to your handlebar to see whether it could pivot unexpectedly during operation. The illustration at right shows the type of motion this procedure tests for. 1. Get the ebike ready for testing. Turn off the ebike, remove the battery, and press and hold the power button to
discharge remaining power. 2. Make sure your handlebar is centered on the stem. Your handlebar has the widest diameter at its center. If it
isn’t centered, it could come loose. Center your handlebar, loosening and re- tightening the stem faceplate bolts as necessary. 3. Brace your front wheel. Roll your ebike up to a wall so that your front wheel is touching the wall and is perpendicular to the wall. Stand over your frame as though you’re about to ride it, and then sit down. If necessary, lower the seat so that you can sit on it while your feet are on the ground. Place both hands on the handlebar and squeeze the brake levers. 4. Push your handlebar. Begin by pushing with medium force, watching for any pivot in the handlebar. Increase the force until you are pushing as hard as you can, ideally with 100 lb of total force. 5. If your handlebar did not pivot, it’s tight enough. If your handlebar did pivot, you will need to loosen and re-tighten the stem faceplate bolts as described in the assembly instructions. Be sure to torque the bolts according to “Tools and torque specifications” on page 12.

WARNING: Improperly securing your handlebar, stem, or stem riser can result in loss of control
of your ebike, serious injury, or death. If you are not sure you have the experience, skills, and tools to correctly perform all steps to secure and verify the security of the handlebar, front wheel, and handlebar stem you MUST consult a professional, reputable bike mechanic to check your work and/or secure those components to the ebike properly.
Guard against rust, corrosion, and water damage
WARNING: Damage to your ebike’s electrical system caused in any manner, including water intru-
sion, can lead to battery failure, electrical system malfunction, or electrical fire and consequent property damage, injury, or death. Follow all instructions to minimize chance of water damage. If you have any questions, contact Rad Power Bikes Product Support.
Like any vehicle used outdoors, your RadRunner 3 Plus needs care to ensure it isn’t damaged by the elements. Follow these steps for a long, healthy life for your ebike:
l Store under shelter and in an upright position; avoid leaving the ebike in the rain or exposed to corrosive substances such as water, salt, or de-icing substances. If exposed to rain, dry your ebike afterward, and apply an antirust treatment to the chain and other unpainted steel surfaces.
l To clean your ebike, turn it and the battery off and wipe the frame with a clean, damp cloth. If needed, apply a mild, non-corrosive detergent mixture to the damp cloth and wipe the frame. Dry by wiping with a clean, dry cloth. Never use high-pressure water on your ebike. Wipe down your ebike frequently and wipe or spray all unpainted mechanical parts with anti-rust treatment.
l If painted metal parts become scratched or chipped, use touch up paint or nail polish to prevent rust. l Never immerse or submerge the ebike or any components in water or liquid, which can damage the electrical
system. l Avoid riding on the beach, in coastal areas with high-salinity fog, or on surfaces treated with salt or de-icing com-
pounds. Doing so exposes your ebike to salt or other substances that are very corrosive. Corrosion of electrical components can lead to permanent damage that can cause battery failure, electrical system failure, or electrical fire. Damage from corrosion is not covered under warranty.

Error detection
Your RadRunner 3 Plus is equipped with an error detection system integrated into the display and motor controller. In the case of an electronic control system fault, an error code should appear on the Rad UI Remote and the Rad UI Display. If your bike has an error code displayed at any time, stop riding and look up the error code information at radpowerbikes.com/help.

Rad UI Remote

Rad UI Display

The Rad UI Display shows the error code as a number.

The Rad UI Remote displays an error code with a large “E” and lighted bars (circled in green in the “Rad UI Remote” illustration). In the same illustration, the lower two bars represent the first digit, “2,” and the top three bars represent the second digit, “3,” to form the error code “23.”

The following error codes are the most common.

Error 21 22 23 24 25 30 31 34

Definition Abnormal current Throttle fault Motor phase fault Motor hall fault Brake switch fault or the brake applied while turning on Communication fault Power button hold fault Walk mode disengage fault

In some cases, a communication error can display as a low battery signal on the Rad UI Remote. If you notice that your Rad UI Remote shows only one battery charge level light, and that light is flashing, check the battery level on the battery itself. If the battery does not also show a very low charge, you should assume you have a communication error (error 30) and follow the connector check guide for your ebike on our Help Center (radpowerbikes.com/help).
If an error code displays, make note of the number or take a picture. Try turning the ebike off and then back on. If the error persists, turn off the ebike and then stop touching it to ensure you aren’t causing the error by accidentally pressing a button, etc. Go to our Help Center (radpowerbikes.com/help) to look up information on the error code.

If the Rad UI Remote shows a single flashing charge-level light, that can indicate either a low battery or a communication error.

Ride as safely as possible
Operating any bike or ebike is an exciting, delightful, and practical way to get around, but like any sport, it involves risk of injury and death. By choosing to ride any bike or ebike, you assume responsibility for those risks.
WARNING: Incorrect assembly, maintenance, or use of your ebike can cause component or per-
formance failure, loss of control, serious injury, or death. Ebikes have parts that non-motorized bikes do not have, and neither the assembly video, assembly steps, or the rest of the manual cover all potential aspects of ebike configuration, maintenance, and repair, which can require specialized tools and skills. We strongly recommend you consult a professional, reputable bike mechanic to assist in the assembly, repair, and maintenance of your RadRunner 3 Plus, or inspect your work if you choose to do it yourself.
Age and ability requirements
You must be age 16 or older to operate the RadRunner 3 Plus. You must also have the physical ability, reaction time, and mental capability to understand and obey all local laws governing ebike usage and to manage traffic, variable road conditions, and sudden situations. If you have an impairment or disability (e.g., visual impairment, hearing impairment, physical impairment, cognitive or language impairment, seizure disorder) or any other limitation that could affect your ability to safely operate a vehicle, consult your physician before operating any bike, ebike, or similar vehicle.
WARNING: This ebike is not to be operated by anyone under the age of 16. Chil-
dren under the age of 16 may lack the necessary judgment and skill to safely operate the ebike, potentially resulting in damage to the ebike, damage to other property, serious injury, and/or death. Please also check your local laws, which may require a higher age. It is your responsibility to know and obey local regulations regarding rider age and other qualifications.
DANGER: Riding any vehicle under the influence of alcohol, drugs, or any substance or condition that
could impair your motor function, judgment, reaction time, or ability to safely operate a vehicle puts you at VERY HIGH RISK of serious injury or death. Operate your ebike or other vehicles only when you’re sober and otherwise physically and mentally prepared to ride safely.
Know and obey all relevant local laws
It is your responsibility to research and understand relevant laws where you ride your RadRunner 3 Plus, which meets the criteria for a Class 2 ebike in the United States. Local laws may cover required helmets and safety gear, required lights and reflectors, required hand signals, where you can legally ride an ebike (bikes and ebikes may have different restrictions), how fast you can go, what (if any) cargo or passengers you can carry, rider age, and more. Before using public transportation–buses, trains, etc.–to transport your ebike, check with the relevant transportation authority for any rules governing weight limits, tire widths, lithium-ion batteries, or any other rules that might pertain to your RadRunner 3 Plus. Make sure you know ahead of time whether and how high you will need to lift your ebike, and make sure you can do that safely.
When you ride on the road, assume you must, at minimum, follow all of the rules that cars must follow. For additional information regarding traffic and vehicle laws, contact the road traffic authority in your area.
Ride appropriately for conditions
Always travel at speeds appropriate for local terrain and conditions as well as your experience level. When in doubt, slow down. Ride with your headlight on, which will make you more visible in any conditions. The headlight will turn on when the ebike is powered on. We recommend you keep it on whenever you ride. Concentrate on the path ahead. Avoid potholes, gravel, ice, wet or oily roads, wet leaves, curbs, train tracks, speed bumps, drain gates, thorns, broken glass, and other obstacles, hazards, and puncture-flat risks.
— 43 —

WARNING: Crossing train tracks or similar grooved or raised surfaces at a diagonal can make the sur-
face “grab” or deflect your wheel, causing your ebike to suddenly get stuck or crash, leading to serious injury or death. Always cross such hazards at a perpendicular angle or, when in doubt, dismount and walk your ebike across.
PATH RIDING Be a good citizen of shared-use paths and facilities. Keep your speed reasonable and below path speed limits, pass carefully and kindly. Use your voice and/or bell to signal your presence to others, especially when passing. Keep in mind that your ebike is heavy, can go at high speeds, and can hurt others if not operated with care.
ROAD RIDING When riding on streets, obey the same road laws as all other road vehicles as well as local rules governing bike or ebike usage. Sharing the road with other vehicles presents many hazards. Always take these precautions: l Expect the unexpected such as opening car doors or cars backing out of driveways. l Be extra careful at intersections and when preparing to pass other vehicles or other cyclists. l Ride predictably, in a straight line, and with the flow of traffic. Never ride against traffic. l Use correct hand signals to indicate turning, and do so well in advance of turning. l Ride defensively. To other road users you may be hard to see. l Increase your visibility by following the tips in “Low-visibility conditions” below.
OFF-ROAD RIDING Riding off road requires close attention and specific skills, and it presents variable conditions and hazards. Don’t ride off road unless you have the appropriate skills. If you choose to ride off road, wear appropriate safety gear and do not ride alone in remote areas.
LOW-VISIBILITY CONDITIONS
WARNING: Riding at night or in other low-visibility conditions (dawn, dusk, fog, rain, mist, snow, etc.)
makes it harder to see and avoid hazards and makes it harder for others to see and avoid you, which increases risk of accidents, serious injury, or death. Wet, slippery surfaces will compound your risk of injury or death. Avoid these conditions whenever possible. If you must ride in these conditions, following the guidelines below can reduce risk.
l Wear reflective and brightly colored clothing. l Slow down. l Use familiar routes with street lighting if possible. l Ensure tire wall, pedal, and other reflectors are installed and unobstructed. l Ensure headlight and taillight/brake light are functioning correctly and unobstructed. Use them.
WET CONDITIONS Your RadRunner 3 Plus is not meant for use in puddles, heavy rain, or streams. Never immerse or submerge this product in water or liquid as the electrical system may be damaged.
WARNING: Riding in wet conditions means slippery hands, feet, and riding surfaces, which greatly
increases your risk of accidents, serious injury, or death. Low-visibility conditions (night, dusk, dawn, fog, mist, rain, snow, etc.) will compound your risk of injury or death. Avoid riding in such conditions. If you choose to ride in wet conditions, you do so at your own risk. Follow the recommendations below to reduce that risk.
l Decrease riding speed to help you control the ebike in slippery conditions. l Brake earlier since it will take longer to slow down than in dry conditions. l Take care to be more visible to others on the road, following the tips in “Low-visibility conditions” above. l Remember that road hazards are more difficult to see when wet, so proceed with extra caution.

EXTREME RIDING There are no appropriate conditions for extreme riding. Although many articles, advertisements, and catalogs depict extreme riding, Rad Power Bikes strongly advises against such inappropriate and dangerous use of its products.
DANGER: Extreme riding puts you at VERY HIGH RISK of serious injury or death. Extreme riding
includes but is not limited to jumps, stunts, or any riding that exceeds your capabilities or the strength and integrity limitations of certain ebike components and/or otherwise leads to dangerous situations. Never engage in extreme riding or any type of riding that exceeds your capabilities.
Wear a helmet and appropriate safety gear
Wear appropriate safety gear including closed-toe shoes. If you are wearing loose pants, secure the bottom using appropriate leg clips or bands to prevent the fabric from flapping and getting caught in the chain or other moving parts. Never use items such as headphones or hoods that can compromise your hearing or field of vision. A local, professional, reputable bike shop can help advise you on what gear is best for the weather and other riding conditions in your area. Maximize your visibility with bright colors and reflective outerwear or vests. Never compromise your ability to be seen or heard by removing your ebike’s reflectors, blocking or removing the headlight or taillight, or removing the bell.
DANGER: Riding any bike, ebike, or similar vehicle without a helmet puts you at
VERY HIGH RISK of serious head injury or death. Always wear a properly fitted helmet that covers the forehead. Many locations require specific safety devices. It is your respon sibility to familiarize yourself and comply with the laws, rules, and regulations where you ride.
