Tightening the stem and handlebar
The remaining instructions in this update document apply only to some RadExpand 5 ebikes within the following serial number ranges. You can find your serial number stamped into the frame on the headtube, just below its four mounting points.

• RE5I21E00004 through RE5L21E0825
• RE5H21T0001 through RE5F21T0171

Some bikes within these ranges may require additional tightening to properly secure the stem faceplate bolts and the stem riser clamp bolt. The following instructions will show you or your bike mechanic how to test the relevant components on your RadExpand 5 bike to see if they need additional tightening, and how to properly adjust any bolts as necessary’s Correctly and safely tightening the bolts on your bike requires the use of one or more high-quality torque wrenches. You will need a torque wrench that can torque to values ranging from 6 Nm to 25 Nm to complete the steps in this update. Ongoing maintenance of any bicycle requires the use of torque wrenches.
Update to v.1-v.5 Owner’s Manual (Letter)
up2205041700 | part # 15-0278-000
WARNING: Improperly securing your handlebar, stem, or stem riser can result in loss of control of your bike, 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 bike properly.
Handlebar twist test
This procedure will test the security of your stem and stem riser.

1. Get the bike ready for testing. Turn off the bike, remove the battery, and press and hold the power button to discharge remaining power.

2. Check that the folding mechanism on the stem riser is properly secured. Press upward on the release button on the stem riser’s locking lever until you can push the lever down, as in the “Release the latch on the stem riser” illustration. Then press the latch back up. Make sure you hear a “click” and that the release button slides downward into position.

3. Brace the front wheel. Stand at the front of the bike, facing the handlebar, and brace the front wheel between your feet and lower legs.
   

4. 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. (9 kg) of force with each hand.

5. Ensure the handlebar and wheel stay properly aligned. The handlebar and handlebar stem should be tightly secured, and the handlebar should remain perpendicular to the front wheel.

6. Repeat the twist test pulling/pushing with the opposite hands, using about 20 lb (9 kg) of force pushing with one hand and 20 lb. of force pulling with the other hand.

7. Check for any movement or changes in alignment of handlebar relative to the front wheel. If there was no alignment change, skip the next section, “Accurately tighten the stem and stem riser.”

Accurately tighten the stem and stem riser
If your bike did not pass the handlebar twist test, follow these steps to ensure your stem clamp and stem riser clamp bolts are properly secured.

1. Ensure the stem clamp bolts (“A” in the illustration) are properly torqued. Use a quality torque wrench to ensure these two bolts are torqued to standard recommended value, 8 Nm.
   Once it is torqued to 8 Nm, repeat the handlebar twist test. If you pass it now, you can skip to the next section, “Handlebar push test.”

2. Ensure the stem riser clamp bolt (“B” in the illustration) is properly torqued. The standard torque recommendation for that bolt is 18 Nm. Use a quality torque wrench to see whether it is torqued to that value. If it is already 18 Nm, but it failed the test, increase the torque value to 23 Nm. Do not exceed 25 Nm.
   WARNING:   Torqueing your stem riser clamp bolt to more than 25 Nm can damage the bolt and lead to component failure, serious injury, or death.

3. Perform the handlebar twist test again to ensure your bike passes it now. If it still does not pass the test, contact Rad Power Bikes Product Support (contact information is located at the end of this update document).

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 bike ready for testing. Turn off the bike, 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 retightening the stem faceplate bolts as necessary.
3. Use a quality torque wrench to check how tight your stem faceplate bolts. The standard recommended torque value is 6 Nm. If they aren’t tight enough, tighten them to 6 Nm.
4. Brace your front wheel. Roll your bike 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.
5. 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. (45 kg) of total force.
6. If your handlebar did not pivot, it’s tight enough and you can skip the section below.

If your handlebar can pivot like this, your stem faceplate bolts need tightening.

Accurately tighten stem faceplate bolts
If you detected any pivot in the handlebar, re-tighten the faceplate bolts to a maximum of 9 Nm.

1. Loosen each stem faceplate bolt. They should be loose enough so that you can adjust your handlebar angle to your preferred position.
2. Tighten each of the bolts with an Allen wrench a little at a time, moving among the bolts in an “X” pattern, until the handlebar is stable.
3. Use a quality torque wrench to tighten each of the bolts to 9 Nm.
4. Reinstall your battery and test the bike fully before riding it.

When tightening the stem faceplate bolts, tighten each a little at a time, moving among the bolts in an “X” pattern.

WARNING:  Incorrect assembly, maintenance, or use of your bike can cause component or performance failure, loss of control, serious injury, or death. Even if you’re an experienced bike rider, you must read and understand the entire manual and any documentation provided for subcomponents or accessories before riding. If you are not sure you have the experience, skills, and tools to correctly perform all assembly steps in the manual and the assembly video at www.radpowerbikes.com/assemble, consult a local, certified, reputable bike mechanic.

1. Unpack the bike. Open the bike box and, with the help of another person capable of safely lifting a heavy object, remove the bike from the bike box, placing it upright on the back wheel and front fork protector plate. Carefully remove the packaging material protecting the bike frame and components, and keep the packaging materials in case you want to ship the bike. Otherwise, recycle these materials, especially cardboard and foam, wherever possible. Remove the small box from the bottom of the bike box and carefully set out the contents. Ensure all of the following pieces are included with the bike:
   • Front wheel
   • Headlight and mount
   • Manual
   • Charger| • Assembly toolkit
   • Pedals (left and right)
   • Keys (two, identical)| • Handlebar stem faceplate hardware bag
   • Front wheel quick release (in fork protector plate)
   • Fenders (rear fender partially installed; front fender packed above rear fender)
   • Fender mounting hardware bag
   ---|---|---

If anything is missing, please contact Rad Power Bikes.
We also recommend the following (not included) for assembly and maintenance:

• Flat-side cutters
• 15 mm pedal wrench
• Bicycle grease| • Clean shop towel or paper towel for cleaning excess grease
• Bike pump with Schrader valve and pressure gauge
• Torque wrench (3-60 Nm) with Allen bits
• A strong friend
---|---
2. Ensure that the folding mechanisms are fully closed. Use caution to keep fingers, clothing, and other objects away from the folding parts and potential pinch points. Always check that these latches are locked before moving or riding the bike.
a. Close the stem riser’s folding mechanism. The stem riser (the vertical part of the bike that holds up the stem and handlebar) comes folded to save room in the box.
Rotate the handlebar stem riser up until the hinge closes. Then fold the stem clasp release lever up and press into the stem until the release lever clicks into place.
b. Check that the folding mechanism on the frame is also latched and securely locked. This mechanism is located just in front of where the pedals rotate. For more information, see the assembly video available at www.radpowerbikes.com/assemble. See “Folding and unfolding your RadExpand 5” on page 23 for more information.

3. Ensure the front fork is facing forward. See the illustration to see what the front fork looks like facing forward vs. backward.
   If necessary, rotate the fork. When the fork is correctly positioned, the brake caliper will be on the rider’s left side (the non-drivetrain side of the bike, without the chain), and cables will pass in front of headtube, not behind it.

4. Install the handlebar following the steps below. For more information, view the assembly video available at www.radpowerbikes.com/assemble.
   a. Locate the handlebar stem faceplate and hardware. Set the bolts and faceplate aside near the handlebar.
   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.
   c. Center the handlebar on the stem. Place the handlebar into position on the stem so it’s centered and so that the handlebar is approximately parallel with the front fork 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 evenly, by moving in an “X” pattern. Ensure the gap between the faceplate and stem is even.
   e. Torque the bolts evenly to the value listed in “Tools and recommended torque values” on page 11. If, in the future, you decide to adjust the angle of the handlebar (e.g., to bring it slightly closer to the seat), be sure to follow the same procedures listed here to ensure the handlebar is properly secured.

5. Install the front wheel onto the front fork as explained below. For more information, see the assembly video at www.radpowerbikes.com/assemble.
   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 to either component, which can decrease braking performance. When installing the front wheel, ensure that you don’t touch the brake rotor or pads with bare hands. Wear clean gloves if needed.
   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 washer and the other cone spring in place on the lever side.
   b. Lightly grease the quick-release skewer. Place about half of a pea- size amount of bicycle grease onto the threaded end of the skewer and then wipe it across the rest of the skewer.
   c. Install the skewer through the front wheel hub, starting from the brake-rotor side. 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.
   d. Carefully lift the front of the bike and lower the fork onto the wheel so that the brake rotor enters the caliper, between the brake pads, and the axle enters the fork dropouts fully. If installing the front wheel is difficult, use a 5 mm Allen wrench to turn the inner pad adjustment dial counterclockwise one or two clicks to increase the space between the brake pads. Try to install the wheel again.
   e. Check that the wheel is fully seated in the dropouts, that the wheel axle is level and parallel to the ground, and that the wheel is centered.
   f. Hold the quick-release lever in line with the axle and tighten the thumbnut until the lever can stay parallel to the floor without being held. Use the palm of your hand to close the lever fully, without touching the brake rotor. The quick-release lever secures the front wheel to the bike, so it’s important that the thumbnut is tight enough that the closed lever has adequate clamping force to keep the axle and wheel firmly in place. When you close the lever, there should be enough resistance that it leaves an imprint in your hand.
   Front wheel: thumbnut (1) and quickrelease lever (2)
   g. Prop the bike on the kickstand.
   h. Check the security of the front wheel and quick-release lever. If it’s too easy or too difficult to close, adjust the lever tension by turning the thumbnut one turn, then close the lever. Check the front wheel security on a regular basis: the front wheel should always be fully seated in the dropouts of the front fork, and the quick-release lever should always be properly secured.

6. Check the security of the rear wheel. The rear wheel security and hardware torque should also be checked on a regular basis (see “Tools and recommended torque values” on page 11 ). Either wheel can become loose or unsecured with normal use.
   WARNING:  An improperly secured front or rear wheel can cause loss of control, accidents, serious injury, or death. Check that both wheels are properly secured during assembly and before each ride.

7. Perform a handlebar twist test to ensure the front wheel and handlebar stem are securely connected. Instructions for doing so are in “Handlebar twist test” on page 32.

8. Install the front fender and headlight.
   a. Locate the fender and mounting hardware.
   b. Remove the headlight mounting hardware from the top of the fork.
   c. Pass the fender from the back of the front wheel, under the fork, as shown.
   d. Install the fender/headlight mounting hardware through the headlight bracket, fender, and fork as shown above. Pass a washer over the bolt end, pass the bolt end through the headlight mounting bracket and the fender mounting point, and then pass the bolt through the mounting point on the fork. 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 recommended torque values” on page 11.
   Pass the fender from the back of the front wheel
   e. Locate the fender mounting hardware. Pass a split washer and a flat washer over each bolt end.
   f. Secure the fender mounting arms. Pass a fender arm eyelet over the mounting point on the bike and thread in the bolt by hand. Repeat with the other fender arm.
   g. Check that the fender and headlight are centered, then torque the fender mounting arm bolts according to the value in “Tools and recommended torque values” on page 11.

9. Complete the installation of the rear fender.
   a. Start on the non-drivetrain side of the bike (the side without the chain). You will need the bag of fender mounting hardware from the previous step. Pass the last split washer and flat washer onto the last bolt, and then pass that bolt through the eyelet of the fender mounting arm into the mounting point near the rear dropout. Tighten by hand.
   b. Secure the other fender mounting arm. On the drivetrain side of the bike, the eyelet of the fender mounting arm will share a mounting point with one of the derailleur bash guard bolts. Locate the derailleur bash guard, and remove the left of its two bolts (the one farthest toward the back of the bike). Take that bolt with its washers, and pass it through the fender mounting arm eyelet, back through the bash guard, and into the mounting point. Tighten by hand.
   c. Torque the rear fender mounting arm bolts on both sides of the bike according to the value in “Tools and recommended torque values” on page 11.
   Securing the rear fender mounting arm with the derailleur bash guard
   

10. Check the bash guard position. The bash guard 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 bash guard is too close to the bike, do the following:
    a. Ensure that the axle nuts are torqued to the value listed in “Tools and recommended torque values” on page 11.
    b. Gently pull the bash guard away from the bike, by hand, until the derailleur can operate correctly.

11. Plug in the headlight connector. Line up the internal notch and pins with the external arrows, and press directly together without twisting.
    Headlight pointing slightly downward to not blind others
    

12. Adjust the headlight angle slightly downward so it won’t blind oncoming traffic. Using the tools listed in “Tools and recommended torque values” on page 11, loosen the angle adjustment bolt and locknut, angle the headlight downward, and tighten securely. Do not overtighten.

13. Install the pedals.
    a. Locate the right-side pedal, 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.

d. Place a pea-size or slightly smaller amount of bicycle grease onto the threads of the left pedal.
e. Carefully thread the left pedal onto the left crank by turning counterclockwise (toward the front of the bike). The reverse threaded left pedal is marked with an “L,” should have an “L” sticker attached, and has notches on the pedal axle. Thread slowly and gently by hand without cross- threading or damaging the threads. See the “Left pedal installation” illustrations.
f. Tighten each pedal using a pedal wrench to avoid damage caused by wider wrenches, as shown in the assembly video at www.radpowerbikes.com/assemble.
g. Torque each pedal to 35 Nm.
h. Wipe off any excess bicycle grease.

---|---|---
Open the quickrelease lever| Insert the seaport, ensuring the minimum insertion
point (circled in orange) goes into the seat tube.| Close the quick-release lever using your palm.
14. Install the seat and seaport. Locate the seat and seaport and then follow these steps:
a. Remove the seat and seaport from the seat tube (the part of the frame that holds the seaport): Open the quickrelease lever on the seat tube and gently pull the seat and seaport out.
b. Apply a thin layer of bike grease to the seaport using a clean shop towel rag, and then wipe off any excess grease.
c. Make sure the quick-release lever on the seat tube is open (see the first illustration at “Installing the seat and seaport” above) and that the quick- release clamp opening is aligned with the notch in the seat tube (see the dotted lines in the illustration).
d. Insert the seaport into the seat tube as shown in the middle illustration at “Installing the seat and seaport” above. Make sure that the minimum insertion point etched onto the seaport goes into the seat tube (it should not be visible). Secure with the quick-release lever, as shown in the third illustration at “Installing the seat and seaport” above. 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 while the lever is open. You can fine-tune the position and angle of the seat later, according to directions in “Adjusting for comfort and safety” on page 12.
DANGER:   Overextending the seaport can cause it to break or fall off your bike, which will put you at very high risk of serious injury or death. Avoid this danger by inserting your seaport into the seat tube far enough that the minimum insertion point is no longer visible.

15. Inflate tires. Check that the tire beads and tires are evenly seated around the rims. Use a 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. Do not overinflate or underinflate tires. For more information, see “Tire and wheel care” on page 31.
16. Complete all steps in “Adjusting for comfort and safety” on page 12, including checking that all hardware has been tightened according to the values in “Tools and recommended torque values” on the next page.

Tools and recommended torque values

The tool sizing listed below is a general guide, but it is possible that the head of a particular bolt on your bike 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 recommended torque 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 www.radpowerbikes.com/help.

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 bike fitting professional such as a certified, reputable bike mechanic who specializes in bike fit.
Adjusting the seat height
An ideal seat height for most riders allows them to be comfortable and get the best pedaling efficiency. When the rider is seated, they should be able to place the ball of their foot on the pedal at its lowest position while their leg is almost fully extended, with the knee slightly bent. The seat should never be so high that the rider must rock side to side or fully straighten their legs while pedaling. And the seat must never be pulled out so far that the minimum insertion point is above the seat tube (see illustration).Seaport out TOO FAR The minimum insertion point on the seaport must be inserted into the seat tube.
Depending on a rider’s preference, ability, and amount of experience with bike and bike riding, lowering the seat so the rider can put one or both feet on the ground without dismounting from the seat may offer a safer and more comfortable experience while operating the bike.

Open the quickrelease lever| Insert the seaport, ensuring the minimum insertion point
(circled in orange) goes into the seat tube.| Close the quick-release lever using your palm.

1. Open the seaport quick-release lever.
2. Slide the seaport in or out of the seat tube to a height appropriate for your leg length and preference. Do not extend the seatrout beyond the minimum insertion marking etched onto the seaport (see the “Seaport out TOO FAR” illustration).
3. Align and close the quick-release lever fully. The quick release clamp opening should align with the notch in the seat tube. 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 quickrelease lever.
4. Try out your seat fit, and repeat steps 1–3 if the seat position needs a bit more adjusting.

Adjusting the seat angle and horizontal position
Many riders will 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. To change the angle and horizontal position of the seat:

1. Use a 6 mm Allen wrench to loosen (but do not remove) the seat adjustment bolt on the clamp located underneath the seat.
   Seat adjustment bolt with Allen wrench

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 the top of the seat rail clamp is aligned directly over the bottom of the clamp so that the seat adjustment bolt will clamp the seat rails properly. Then, while holding the seat in the desired position, use a 6 mm Allen wrench to tighten the seat adjustment bolt securely to the torque value listed in “Tools and recommended torque values” on page 11.

WARNING:  A loose seat clamp or seat adjustment bolt can cause loss of control, bike/property damage, serious injury, or death. Prior to first use, be sure to tighten the seat clamp via the seat adjustment bolt properly. Regularly check to make sure that the seat adjustment bolt is properly tightened and the clamp is secure on the seat rails.
Adjusting the 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 center position in 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. To change the angle, loosen the stem faceplate bolts just enough to allow the handlebar to pivot, and position it as you prefer. Re-tighten the stem faceplate using the method described in the assembly instructions. Sit on the bike and test the positioning, making sure the handlebar can turn freely without touching your body. Be sure the gap between the faceplate and stem are even and torque all faceplate bolts according to the value listed in “Tools and recommended torque values” on page 11.
Fine-tune the brake lever positioning
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 recommended torque values” on page 11.

TIP! Another way to maximize hand comfort while riding is to ensure your handlebar grips are angled so that the wide section of the grip is positioned directly under the outside part of your palm while your wrists are in a neutral position and you have 2-3 fingers resting on the brake levers. This allows you to distribute your weight over a larger portion of your hand. 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: carefully insert a screwdriver between the handlebar tubing and the grip, pry the grip away from the handlebar slightly, then use a paper towel or squeeze bottle to apply the alcohol into the gape
Fine-tune brake lever feel
The “feel” of the brake levers is controlled by the brake cable tension, which determines how far the brake levers need to be squeezed for the brake pads to press against the brake rotor. We recommend that the brake cable tension be such that squeezing the levers halfway between the starting position and the handlebar grip results in a firm lever feel, indicating that the brake pads are pressing against the brake rotor.
If needed, you can make fine adjustments to the brake cable tension by rotating the barrel adjusters at the brake lever housings and/or at the brake calipers.
For more information on brake lever feel and brake cable tension, please see the resources in our Help Center at www.radpowerbikes.com/help.
**DANGER:   A brake lever that can touch the handlebar grip when squeezed can result in the brake caliper not pressing the pads into the brake rotor fully or at all, which means that the brake will not function properly or at all. Not being able to brake the bike puts the rider at a high risk of serious injury or death. Always make sure that squeezing the brake lever does not cause it to touch the handlebar grip. Also make sure that a squeeze of the brake lever to halfway between the lever’s neutral position and the handlebar grip results in the brake caliper pressing the brake pads against the brake rotor.
Ensure all hardware is tightened properly**
Ensure all hardware is tightened properly according to the values in “Tools and recommended torque values” on page 11. 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, certified, reputable bike mechanic for help. You can find more information about bike fit and making adjustments to your bike in our Help Center at www.radpowerbikes.com/help.

Before you charge
Before you charge your battery, make sure to first check the battery, charger, and electrical cables for signs of damage. Store and use the charger in a safe place—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 battery malfunction. Position the charger and battery where they’re not at risk for falls or other impacts.
WARNING:  Letting the charger’s plug contact metal objects could cause a power discharge (a spark), which could injure you or create a fire hazard.
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.
Your battery needs to charge at room temperature or a bit cooler (50°F to 77°F (10°C to 25°C)). It generates heat while charging, but it’s designed to air- cool; keep it uncovered and the lights facing upward on a flat, stable, hard surface.
NOTICE: Charging your battery in excessively hot conditions or interfering with its ability to air-cool can damage your battery or charger. Always charge your battery at room temperature: 50°F to 77°F (10°C to 25°C). Charging your battery at low temperatures may slow charging or prevent a full charge. Keep the battery and charger  uncovered, make sure the charger is on a hard, flat, stable surface, and use the charger right-side-up (with charging lights facing upward).
Charging procedure
To charge your battery, mind the advice in “Before you charge” above and then follow these steps.

Keyport & key positions

| Description
---|---
A| Power on, battery locked to frame
B| Power off, battery locked to frame
C| Power off, battery unlocked from frame (for battery installation and removal)

1. Ensure the battery power is off. Align the Keyport with the appropriate off position by inserting the key into the Keyport and rotating to align the key with one of the battery power “off” icons:
   • The “Power off, battery locked to frame” icon (position B in the illustration): Use this position for charging with the battery on the bike.
   • The “Power off, battery unlocked from frame” icon (position C in the illustration): Use this position for charging the battery removed from the bike. Align the key with this position, remove the key from the battery, and then remove the battery from the bike.

4. Plug the charger into a power outlet. Connect the charger input plug (100/240-volt plug) to the power outlet. Charging should initiate and will be indicated by both LED charge status lights on the charger turning red. When charging is complete, one indicator light will turn green and the other will remain red.

5. Unplug the charger from the outlet, then the charging port. Once fully charged, indicated by one charging indicator light turning green (and one remaining red), unplug the charger from the wall outlet first and then remove the charger output plug from the battery charging port. Be sure to pull gently on the plugs, not on the cables themselves.

NOTICE: The charger is designed to stop charging automatically when the battery is full. Nevertheless, leaving your battery charging longer than necessary can cause needless wear. We recommend you remove the charger from the battery within one hour of the green light indicating a complete charge. Store the charger carefully, making sure its plug does not come in contact with liquids, dirt, debris, or metal objects, which can damage the plug and interfere with future operation.
TIP! We recommend you follow these steps when plugging in and unplugging your charger.
To plug in your charger:

1. Start with the charger unplugged from both the power outlet and battery.
2. Plug the charger into the battery.
3. Plug the charger into the power outlet.

To unplug your charger:

1. Start with charger plugged into both the power outlet and battery.
2. Unplug the charger from the power outlet.
3. Unplug the charger from the battery.

WARNING:  Charging your battery with a charger other than one supplied by Rad Power Bikes and designed for your specific bike serial number can cause damage to your bike’s electrical system or create a fire hazard. Only use a battery charger designed for your bike and supplied by Rad Power Bikes.
Estimated charging time
The time the charger takes to fully charge the battery depends on distance traveled, riding characteristics, terrain, payload, battery age, and other factors. The table provides a rough estimate of charge time based on common distances traveled in regular operation.
NOTICE: The battery may take longer to charge when fully depleted, when very new, and after 3–5 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.

Long-term battery storage
If storing your bike from Rad Power Bikes for longer than two weeks at a time, follow the recommendations below to maintain the health and longevity of your battery.

• Store the battery in a dry, climate controlled, indoor location between 50°F to 77°F (10°C to 25°C).
• We recommend that you store your battery at approximately 40-75% charged. Check the battery’s charge level monthly. If necessary, use the charger from Rad Power Bikes to charge the battery to about 40-75% charged.
• 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.

NOTICE: Incorrect storage of your battery can result in a damaged or non- functional battery. Follow the above recommendations to reduce such risk.

Operation

WARNING:  Incorrect assembly, maintenance, or use of your bike can cause component or performance failure, loss of control, serious injury, or death. Even if you’re an experienced bike rider, you must read and understand the entire manual and any documentation provided for subcomponents or accessories before riding. If you are not sure you have the experience, skills, and tools to correctly perform all assembly steps in the manual and the assembly video at www.radpowerbikes.com/assemble, consult a local, certified, reputable bike mechanic.
How the electrical system works
Your RadExpand is equipped with two ways for a rider to use power assistance from the motor to propel the bike forward: a pedal assist system (PAS) and a twist throttle.
HOW PEDAL ASSIST WORKS
The rider can engage the pedal assist system (PAS) while pedaling, and it will call up assistance from the motor to help propel the bike forward.
Pedal assist uses a cadence sensor built into the drivetrain of the bike. The cadence sensor detects when the rider revolves the pedals and signals the electric motor to provide the level of pedal assistance (0-4) that the rider has selected.
HOW THE THROTTLE WORKS
The throttle is located on the right side of the handlebar. The rider can use it with a twist of the throttle grip to propel the bike forward without pedaling.
To engage the throttle while riding, slowly and carefully rotate it toward yourself. The more you twist, the more powerfully the motor will propel the bike forward. Once you release the throttle or apply the brakes, the throttle will no longer propel the bike forward. Always keep one hand on the brake lever and be prepared to squeeze the lever to disengage the throttle if needed, or turn off the bike to prevent accidentally engaging the throttle.
Some bikes 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 bike regulations, rules, and traffic laws where you ride.
Battery key positions
Familiarize yourself with the Keyport and key positions before riding the bike. Always remove the key before getting on your bike to ride it.

Keyport & key positions

| Description
---|---
A| Power on, battery locked to frame
B| Power off, battery locked to frame
C| Power off, battery unlocked from frame (for battery installation and removal)

• Any time the battery is in key position A, (power on, battery locked to the frame) the power button on the LED display will turn the bike on and off, and the battery cannot be removed.
• If the battery is in key position B, (power off, battery locked to the frame) no buttons or controls can be activated, the bike will remain off, and the battery cannot be removed.
• Any time the battery is in key position C, (power off, battery unlocked from the frame) the battery must be removed from the bike before moving or riding the bike. Ensure the key is removed before sliding the battery out of the mount.

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

Note: Some bikes may come with slightly different components. Such changes help ensure uninterrupted shipping. Our engineers rigorously test each component to guarantee quality and compatibility.

  CAUTION: Using walk mode inappropriately can cause you to lose control of the bike, causing bike damage or injury.
  Use walk mode only while dismounted from the bike, with both hands on the handlebar, and with at least one hand on a brake lever so that you can quickly cut off power to the motor if necessary.
  Start-up procedure
  After the bike has been properly assembled according to the assembly video, all components are secured correctly, a certified, reputable mechanic has checked the assembly, and you have read this entire manual, turn on the bike and select a pedal assist level following the steps below:

  1. Familiarize yourself with the key positions.
     The “Keyport & key positions” illustration shows the Keyport in position B, in line with the small circle icon with and “X” through it. In key position B, the battery power is off and battery is locked to the frame.
     Keyport & key positions
     | Description
     ---|---
     A| Power on, battery locked to frame
     B| Power off, battery locked to frame
     C| Power off, battery unlocked from frame (for battery installation and removal)

  2. Check that the battery is locked securely. Ensure the Keyport is aligned with the circle containing an “X,” in the “Power off, battery locked” position (B) as explained above. If needed, insert the key and align with the “Power off, locked” icon (B). Remove the key and carefully use both hands to pull up on the battery to test that the lock is secure.
     CAUTION: Getting onto the bike 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 bike.

  3. Turn on the bike. With the battery locked in place, insert the key and turn clockwise to the open circle icon, which is the “Power on, battery locked to frame” position (A), as shown in the image above. Remove the key by pulling directly backward without twisting so the key position remains in the “Power on, battery locked to frame” position. Locate the LED display (near the left handlebar grip). Hold down the power button for approximately two seconds until power is delivered to the LED display and the headlights turn on.

  4. 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 the previous page.

  5. Select your desired level of pedal assistance (PAS) from 0 through 4 using the up and down arrows on the LED display. Level 0 provides no pedal assistance, level 1 provides the lowest amount of pedal assistance, and level 4 provides the highest amount. Start in PAS level 0 or 1 and increase PAS levels one at a time as you get comfortable.
     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.

  6. Begin riding carefully. With the proper safety gear and rider knowledge, you may now operate your bike from Rad Power Bikes. Begin by pedaling on flat ground, clear of obstacles and people, with the bike 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.
     NOTICE: While you’re getting to know your bike, don’t ride with cargo (see “Carrying cargo ” on page 25 for more information). Review, understand, and follow the safety information in “Ride as safely as possible” on page 34.

  7. 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 bike, 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.
Brake light features and operation
The RadExpand is equipped with a taillight/brake light that is integrated into the electrical system. When you turn on your bike, both the headlight and taillight will illuminate to make you more visible to other vehicles. Any time the bike is powered on, squeezing one or both brake levers on the handlebar will activate the brake light, causing the taillight to illuminate additional areas.
NOTICE: Flashing lights may not be legal in some areas. It is your responsibility to know and obey all applicable laws where you ride your bike.
Battery capacity display
The display on the handlebar of your RadExpand features a battery capacity gauge (like a fuel gauge on a car). This gauge calculates the remaining battery charge based on the current battery power output (instantaneous voltage reading), and can fluctuate while riding as power demand and/or output changes.
Once only one bar is illuminated, users should charge the battery as soon as possible. At lower states of charge, the bike may limit power output to make the remaining power last a little bit longer. When the battery is fully depleted, the last bar will begin to flash, alerting the user that they’re about to lose all electrical power. Any time your power is off or depleted, you can still propel your bike by pedaling it.

Driving range
We suggest that you select a lower pedal assistance level when you’re getting to know your RadExpand and travel routes. Once you become familiar with your range requirements and the capabilities of your bike, you can adjust your riding characteristics if you desire.
The table in this section provides range estimates under example conditions to help owners 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):| •Hilly terrain
•Windy| •Light pedaling
•Heavy payload| •High pedal assist level, high throttle use
---|---|---|---
35 mi (56 km):| •Flat terrain
•Not windy| •Light pedaling
•Normal payload| •Low pedal assist level, minimal throttle use
45 mi (72 km):| •Flat terrain
•Not windy| •Moderate to heavy pedaling
•Normal payload| •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.

• Whenever possible, avoid applying full throttle when the bike has slowed to very low speeds, has stalled, or stopped.
• Pedal to assist the motor when climbing hills and accelerating from a stop.
• Reduce your power consumption whenever possible.
• Do not climb hills steeper than 15% in grade.
• Avoid sudden starts and stops.
• Accelerate slowly.

Folding and unfolding your RadExpand 5
NOTICE: Use caution to keep fingers, clothing, and other objects away from the folding mechanisms and potential pinch points on your bike.
Always check the folding mechanisms to ensure they’re locked before you ride or move your bike.
Follow the procedures below to fold and unfold your RadExpand 5. Demonstrations of this process are available via the Rad Power Bikes Help Center at  www.radpowerbikes.com/help.
FOLDING

1. Stand at the left side of the bike and ensure the crank arms are parallel to the ground.

2. Open the frame locking mechanism (it’s located just forward of the pedals).
   a. Unseat the locking lever. Press upward on the small, triangular locking clasp on the locking mechanism and, at the same time, pull the mechanism’s quick-release lever out and toward the back of the bike. See the illustration.
   b. Unhook the back of the locking lever to release the locking mechanism.

3. Fold the frame. Turn the front wheel slightly left and fold until both wheels are side by side. Rest the bike on the frame stand under the cranks.

4. Secure the frame with the Velcro strap if desired.

5. Fold the stem riser (the vertical part of the bike that holds up the handlebar).
   a. Stand on the left side of the bike so that you can see the folding mechanism clearly.
   b. Press upward on the release button in the center of the locking lever (see illustration). While the button is pushed all the way up, pull down on the locking lever until it comes to rest roughly parallel with the stem. The stem will still be locked. At this point, use one hand to steady the handlebar before you start to fold the stem.
   c. Push the locking lever down further to ensure the latch bolt releases the top part of the stem riser (see illustration). The locking mechanism will be fully open now.
   d. Gently fold the stem riser so that its top rests against the bike frame.

6. If you need to move the folded bike, tilt it onto the front wheel and roll carefully. You can also lift and carry it carefully either alone or with help.

UNFOLDING
Reverse the folding steps listed above to unfold the frame and secure the frame locking mechanism.
WARNING:  Riding your bike with either of the locking mechanisms not fully secured can cause damage to the bike, serious injury, or death. Before each ride, check to ensure that locking mechanisms on the frame and on the stem riser are fully closed and locked.
Parking, storage, and transport
Please follow these tips to ensure your bike is well cared for when you’re not using it.

PARKING AND STORAGE

• Park in accordance with local rules and regulations, especially if you’re in a public place.
• 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 bike systems to dry out. When any bike is exposed to wet conditions, it will need a more frequent maintenance schedule to prevent rust and corrosion and to  ensure all systems work safely. See “Guard against rust, corrosion, and water damage” on page 32 for more information.
• Avoid parking or storing your bike in direct sunlight, which can cause damage to the display.
• Do not park or store your bike in excessive heat, such as inside of a parked car on a hot day. Always store your bike within this temperature range: -4°F to 140°F (-20°C to 60°C).
• Switch the power and any lights off to conserve battery power. Remove the key from the bike and ensure the battery is locked to the frame in the off position or use the key to remove the battery and bring it with you for security.
• Register your bike with Bike Index, 529 Garage, or a regional bike registry (ask your local bike shop for recommendations) to increase the chance you’ll get your bike back in the unfortunate event it’s stolen.
• Lock up your bike to reduce risk of theft. You can purchase a lock from our website at www.radpowerbikes.com or consult a local, certified, and reputable bike shop.

TRANSPORTING

• When pushing or carrying the bike, turn off the power to avoid accidental acceleration from the motor, e.g. by mistakenly twisting the throttle. Another option is to keep the bike powered on and use “walk mode”—see “Electrical controls and operation” on page 20 for more information.
• Only use racks (i.e., a bike rack for your car or other vehicle) designed for the size and weight of your bike. Pay particular attention to whether the rack can accommodate the width of your bike tires. Racks are available for purchase at www.radpowerbikes.com.
• When carrying your bike on a rack for transport, remove the battery, and place/wrap it securely inside your vehicle, making sure it can’t roll around and that its plugs and contacts are protected. This will reduce the weight of the bike, make lifting and loading it easier, and keeps your battery safer.
• 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.
• Before using public transportation (buses, trains, etc.) to transport your bike, check with the relevant transportation authority for any rules that might pertain to bikes, including rules governing weight limits, tire widths, lithium-ion batteries, etc.
• Avoid transporting bike(s) from Rad Power Bikes on a vehicle rack during rain, which may cause water damage to the electrical components. See “Guard against rust, corrosion, and water damage” on page 32 for more information.

Carrying cargo

Carrying cargo can help you have more fun on your bike and replace trips you’d otherwise make with a car, which we think is rad. It also involves additional risks, which require special attention and care. 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 bike with cargo.
Rad Power Bikes provides a wide range of accessories to make it easier to carry cargo. Your RadExpand is not designed to carry passengers, and its rear rack is not compatible with the Thule Yapp child seat.
For more information on optional accessories for your bike, please go to www.radpowerbikes.com.
DANGER:   Only one person—the rider—should be on the RadExpand at a time. Transporting a passenger (any person in addition to the rider) on the RadExpand can result in serious injury or death to either or both the rider and the passenger. The RadExpand is not designed for carrying passengers, and its rear rack is not compatible with Thule Yapp child carriers.
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 bike.
Weight limits
The total maximum weight limit (payload capacity) of the RadExpand, listed below, includes the weight of the rider as well as clothing, riding gear, cargo, accessories, etc. Always hold onto the bike when cargo is being loaded or in place.
Total maximum payload of the RadExpand: 275 lb. (125 kg)
Rear rack maximum payload: 55 lb. (25 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 www.radpowerbikes.com/help.
WARNING:  Never exceed the payload limit of any accessory or component of your bike 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.
Carrying loads (cargo) safely
Follow these recommendations to maximize safety when using your RadExpand to carry cargo.

• 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 bike. Extra weight will increase the time it takes to slow the bike when braking.
• Practice riding with light cargo in a flat, open area that’s free of obstacles before attempting to ride with heavier loads, and/or in wet or hilly conditions.
• With extra weight on your bike, 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.
• Load cargo as low as possible to keep the bike’s center of gravity low and improve stability.
• Hold onto the bike when loading and carrying cargo. The kickstand is not designed to be used for loading cargo. Do not assume the bike is stable and balanced when using the kickstand.
• 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.
• When carrying heavy loads, plan your routes to avoid challenging hills and other hazards.
• It is always the rider’s responsibility to ensure cargo loaded on the bike will not interfere with the rider’s ability to safely operate the bike.

WARNING:  Failure to ensure that cargo can’t interfere with the rider’s control of the bike can lead to serious injury or death. The rider is always responsible for securing loads, loose straps, and other items.
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.
WARNING:  Loading cargo without holding onto the RadExpand can cause the bike to tip, leading to damage or serious injury. The optional kickstand is designed to hold up an unoccupied, unloaded bike on a hard, flat, stable surface, not to support the weight of a rider or cargo. Always hold onto the bike when loading or unloading cargo.
WARNING:  Using the front brake by itself can cause excessive stress on components, damage to the bike and parts, loss of control, injury, or death. Always apply the rear brake before applying the front brake, using both brakes for all operations.
Carrying pets
Rad Power Bikes understands that you may want to bring your pet along on your bike adventures, and we think that’s rad. We urge you to take great care to protect your furry friend and yourself. To check out the pet accessories that we have tested for safety and compatibility with our bikes, please visit www.radpowerbikes.com. We cannot recommend any pet carrier or restraint system that we have not tested for compatibility and safety with your bike from Rad Power Bikes.
WARNING:  Transporting a pet using any bike puts you and your pet at risk of injury or death, especially if the pet distracts you, affects your balance, interferes with moving bike parts, etc. It’s impossible to anticipate every situation that can occur while riding with a pet. If you carry a pet on any bike, you assume any and all inherent risks.

Maintenance

Follow these maintenance guidelines to ensure your RadExpand is safe and fun to ride.
Check and service your bike regularly
On any bike, certain parts need to be replaced periodically due to wear, and sometimes parts become damaged for various reasons. Check your bike before each ride by  following the directions in “Safety checklists” on the next page. Have your bike regularly serviced by a certified, reputable bike mechanic. See “Recommended service intervals” on page 29 for more information.
Components of any bike are subject to higher wear compared to the components of bikes without power assistance. This is because bikes 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, suspension forks, spokes, wheels, and the battery.
If you need to replace a part on your bike, visit www.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 bike model.
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 bike may void your warranty, create an unsafe riding condition, result in bike/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.

Checking brakes & motor cutoff switches
All vehicles, including your RadExpand, need reliable brakes. Test your brake levers, brakes, and motor cutoff switches for proper functioning before every ride. If anything seems wrong, take your bike to a local, certified, and reputable bike mechanic, refer to our Help Center (www.radpowerbikes.com/help), or contact Rad Power Bikes Product Support.
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 bike. Touching the brake rotor with bare skin can also transfer natural oils to the rotor, which can decrease braking performance. Do not touch the brake rotor, especially when it’s in motion or after you’ve been riding your bike. 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.

1. Test the brake levers.
   a. Fully squeeze each lever, and ensure neither the front nor rear brake lever touches the handlebar grips.
   b. Ensure both brake levers are properly lubricated. If they are, they’ll be reasonably easy to squeeze without feeling as though there’s grit in the mechanism. When you release them, they will immediately go back to their original position.
   c. Make sure each lever is properly oriented and firmly secured to the handlebar.

2. Test each brake.
   a. Squeeze the left brake lever to lock the front brake, and then try to push the bike forward using the handlebar. The front wheel should not spin.
   b. Squeeze the right brake lever to lock the rear brake. Again, push against the handlebar to try moving the bike forward. The rear wheel should not spin.

3. Test the motor cutoff switches. The front and rear brake levers contain motor cutoff switches, which cut off power from the motor whenever the brakes are applied.
   a. In a clear, open area, turn on the bike. With appropriate safety gear and clothing, sit on the bike.
   b. Squeeze the left brake lever to engage the front brake.
   c. Lightly apply the throttle. The bike should not move since the brake is applied.
   d. Release the throttle.
   e. Release the brake.
   f. Test that the throttle now operates with the brake not engaged.
   g. Release the throttle.
   h. Perform steps “a”–”g” again, this time with the rear brake lever (on the right side of the handlebar).

Tire and wheel care
The tires and inner tubes that came with your bike 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 range stamped onto the tire sidewall. For additional information about tire pressure, please consult our Help Center at www.radpowerbikes.com/help.
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 should 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 certified, 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 RadExpand, 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 bike again. Otherwise, you risk bike/property 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:  Aftermarket tires or inner tubes not provided by Rad Power Bikes may not be compatible with your wheels or the performance requirements of your bike. 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 bike frame. For safety, and if required by law, ensure replacement tires have sufficient reflective sidewall striping.
For more information on tire or tube replacement, visit www.radpowerbikes.com/help or contact Rad Power Bikes Product Support.
Handlebar twist test
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.

1. Brace the front wheel. Stand at the front of the bike, facing the handlebar, and brace the front wheel between your feet and lower legs.

2. 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.

3.  Ensure the handlebar and wheel stay properly aligned. The handlebar and handlebar stem should be tightly secured, and the handlebar should be perpendicular to the front wheel.

4. 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.

5. If needed, align the handlebar and stem and torque the stem clamp bolts evenly. Instructions for doing so are in
   “Assembly instructions for the RadExpand” on page 4. Be sure to torque the stem clamp bolts evenly to the specification listed in “Tools and recommended torque values” on page 11. After torqueing the stem clamp bolts to the proper specification, perform the twist test again. If the handlebar still moves, contact Rad Power Bikes Product Support.

WARNING:  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 certified, reputable bike mechanic to check your work and/or secure those components to the bike properly.
Guard against rust, corrosion, and water damage
WARNING: Damage to your bike’s electrical system caused in any manner, including water intrusion, can lead to battery failure, electrical system malfunction, or electrical fire and consequent property damage, injury, or death. Follow all recommendations to minimize chance of water damage. If you have any questions, contact Rad Power Bikes Product Support.
Like any vehicle used outdoors, your RadExpand needs care to ensure it isn’t damaged by the elements. Follow these steps for a long, healthy life for your bike:

• Store under shelter and in an upright position; avoid leaving the bike in the rain or exposed to corrosive substances such as water, salt, or de-icing substances. If exposed to rain, dry your bike afterward, and apply an anti-rust treatment to the chain and other unpainted steel surfaces.
• To clean your bike, turn the bike and battery off and wipe the frame with a clean, damp cloth. If needed, apply a mild, noncorrosive 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 bike. Wipe down your bike frequently and wipe or spray all unpainted mechanical parts with anti-rust treatment.
• If painted metal parts become scratched or chipped, use touch up paint or nail polish to prevent rust.
• Never immerse or submerge the bike or any components in water or liquid, which can damage the electrical system.
• Avoid riding on the beach, in coastal areas with high-salinity fog, or on surfaces treated with salt or de-icing compounds.
  Doing so exposes your bike 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.

If this happens, we recommend that you cease operation, take a short video of the light(s) flashing if possible, and then go to the Rad Power Bikes online Help Center (www.radpowerbikes.com/help) for more information. The following errors are the most common and can aid in troubleshooting.

Ride as safely as possible

Ride Rad by taking the sensible measures outlined in this section to maximize your safety. Bicycling 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 a bike, you assume responsibility for those risks.
WARNING:   Incorrect assembly, maintenance, or use of your bike can cause component or performance failure, loss of control, serious injury, or death. Even if you’re an experienced bike rider, you must read and understand the entire manual and any documentation provided for subcomponents or accessories before riding. If you are not sure you have the experience, skills, and tools to correctly perform all assembly steps in the manual and the assembly video at www.radpowerbikes.com/assemble, consult a local, certified, reputable bike mechanic.
Be thoroughly educated about your bike before riding it
Practice riding your bike, braking, shifting gears, and using the throttle and pedal assist systems in a controlled location before venturing into traffic or other risky conditions.
The electrical system on your bike (see “Electrical controls and operation” on page 20) offers various levels of power assistance and lighting for different operating conditions and user preferences. Be sure you understand these features before riding. The throttle should provide smooth acceleration when gradually applied. If the pedal assistance, throttle, or lighting is functioning abnormally, intermittently, or not at all, please discontinue using your bike immediately and contact Rad Power Bikes Product Support for assistance.
Take extreme care getting to know and learning to control the pedal assist and brake systems. Your RadExpand is probably heavier than other bikes you’ve ridden, and it will handle quite differently from lighter bikes, especially when you’re accelerating or decelerating. Learn to maintain a comfortable stopping distance from all other objects, riders, and vehicles at different speeds, conditions, and with varying payloads.
Age and ability requirements
WARNING: This bike is not to be operated by anyone under the age of 16. Children under the age of 16 may lack the necessary judgment and skill to safely operate the bike, potentially resulting in damage to the bike, 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.
Riders 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 riding any bike.
**DANGER:    Riding any bike 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 bikes and 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 bike. Such laws may cover required helmets and safety gear, required lights and reflectors, required hand signals, where you can legally ride a bike (bikes and bikes 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 bike, 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 bikes.
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.
Safety check before each ride
Before each ride, you must check your bike to ensure everything is working properly. Follow the instructions on the “Safety checklists” on page 27 and ground your safety checks in a solid understanding of bike maintenance, which is explained in “Maintenance” on page 26, a section that includes an important chart, “Recommended service intervals” on page 29, which you should follow as well.
If you are ever unsure how to check or maintain your bike or if you find any problems with it, take it to a certified, reputable bike mechanic or contact Rad Power Bikes Product Support.
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.
WARNING:  Using the front brake by itself can cause excessive stress on components, damage to the bike and parts, loss of control, injury, or death. Always apply the rear brake before applying the front brake, using both brakes for all operations.
Always use a low pedal assist level until you are comfortable with your RadExpand and confident about controlling its power, weight, and responsiveness (e.g., during start-up, turns, and braking) at different speeds, in different conditions, and with whatever payloads you might carry.
Riding with your headlight on will make you more visible in any conditions. The headlight will turn on when the bike 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.
WARNING:  Crossing train tracks or similar grooved or raised surfaces at a diagonal can make the surface “grab” or deflect your wheel, causing your bike 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 bike 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.
ROAD RIDING**
When riding on streets, obey the same road laws as all other road vehicles as well as local rules governing bike or bike usage.
Sharing the road with other vehicles presents many hazards. Always take these precautions:

• Expect the unexpected such as opening car doors or cars backing out of driveways.
• Be extra careful at intersections and when preparing to pass other vehicles or other cyclists.
• Ride predictably, in a straight line, and with the flow of traffic. Never ride against traffic.
• Use correct hand signals to indicate turning, and do so well in advance of turning.
• Ride defensively. To other road users you may be hard to see.
• 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.
HOT OR COLD CONDITIONS
Riding, parking, or storing your bike in excessively hot conditions can cause damage to the display and other components. Do not park or store your bike in direct sunlight for extended periods. For more information on safe and recommended temperature ranges for your battery, see “Battery information” on page 15.
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.

• Wear reflective and brightly colored clothing.
• Slow down.
• Use familiar routes with street lighting if possible.
• Ensure tire wall, pedal, and other reflectors are installed and unobstructed.
• Ensure headlight and taillight/brake light are functioning correctly and unobstructed. Use them.

WET CONDITIONS
This electric bike 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. If you must ride in wet conditions, following the guidelines  below can mitigate risk somewhat.

• Decrease riding speed to help you control the bike in slippery conditions.
• Brake earlier since it will take longer to slow down than in dry conditions.
• Take care to be more visible to others on the road, following the tips in “Low-visibility conditions” on the previous page.
• 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 recommends 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 bike 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
We strongly advise that you wear a properly fitting, certified bicycle safety helmet while riding your bike, which may be required by law in your area.
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, certified, and 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 bike’s reflectors, blocking or removing the headlight or taillight, or removing the bell.
  DANGER:    Riding any bike 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 responsibility to familiarize yourself and comply with the laws, rules, and regulations where you ride.
