It is the responsibility of the rider to ensure all parts are in working order prior to riding this electric bicycle.

What Never To Do When Riding

• NEVER ride without wearing an approved helmet, which must meet
• lUSA/European (CPSC/EN) standards. Always comply with the local laws lland ordinances.
• NEVER ride on the same side of the road as oncoming traffic.
• NEVER carry a passenger as this bicycle is designed for a single rider only.
• NEVER hang item(s) over the handlebar as this could interfere with steering or catch in the front wheel causing a crash.
• NEVER hold on to another motor vehicle or bicycle.
• NEVER ride too close to another vehicle—stay aware and keep your distance.
• WARNING! Wet Weather Riding: Your bike’s brakes do not work as well under wet or icy conditions as they do under dry conditions. The braking distance in wet weather will be longer than that in dry conditions. Take special precautions in wet weather to assure safe stopping. Ride slower than normal and apply your brakes well in advance of anticipated stops.

WARNING! Night Riding: Do not ride at night. If you have to be on your e-bike at night or in low-light conditions, always comply with laws and regulations (local and otherwise) for bicycle lighting. Use approved headlights (white), taillights (red) properly affixed to your e-bike in addition to all-around
reflectors. For additional safety, wear light colored clothing with reflective stripes, or safety yellow or safety orange clothing. Check that the reflectors are firmly secured in the correct position and clean and not obscured. Damaged reflectors must be replaced immediately.

WARNING! The seat post must be inserted at least up to the minimum insertion mark, or further so the insertion line is no longer visible (Fig. 4).
If not, the seat post may bend or break, possibly damaging the bicycle or causing injury.

WARNING! Handlebar stem minimum insertion mark on traditional quill stem must NOT be visible above the top of the headset. If the stem is extended beyond the minimum insertion mark, the stem may break or weaken the fork steering tube, possibly damaging the bicycle or causing an accident (only for bike equipped with a quill stem).

Routine Maintenance Check and Lubrication

WARNING! As with all mechanical components, your bicycle is subjected
to wear and stress. Different materials and components may react to wear or fatigue in different ways. If the design life of a component has been exceeded it may suddenly fail, possibly causing injuries to the rider. Any types of cracks, scratches, or change of coloring in highly stressed areas indicate that the life of the component has been reached and it should be replaced immediately.
Always inspect your bicycle before every ride.

WARNING! Use only genuine replacement parts, particularly for safety- critical components, installed by a professional bicycle mechanic. To keep your electric bicycle functioning well, the following routine maintenance lubrication is necessary (refer to Fig. 5)

Half-Yearly: Remove, clean, and lubricate chain, derailleur(s), cog set, and all cables. Check and replace as required.
Weekly (or as needed): Wash bicycle with warm soapy water. Dry with a soft, nonabrasive cloth. Do not use strong chemicals or abrasives. Do not use a high-pressure washer. Inspect your bicycle while cleaning.

WARNING! Every six months, your pedal electric assistance bicycle should be professionally checked to ensure that it is in correct and safe working order. It is the responsibility of the rider to ensure all parts are in working order prior to riding.

6. Rotate the handlebars (and fork) to face forward.

7. Examine your new bike for any visible damage which may have occurred during shipping.
   

8. Step 2: Fender, Headlight and Front Wheel Installation
   2.1 Installing the Front Fender and Headlight

9. Unwrap both the fender and the headlight.

10. Locate the long bolt, washer, and nut which will either be in the parts bag/box or inserted in the top of the fork. If it is threaded into the top of the fork arch, remove it using the 5mm hex wrench.

11.  Slide the tab at the top of the fender in front of the fork arch hole at the back. Place the light mounting bracket on top of the fork tab in the same position. Insert the bolt through both and snug tight with the 5mm hex. (Fig6)

12. Position the fender struts to the mounting tabs on the fork. It is okay to squeeze inward as these braces are designed to be pliable. Using the 4mm hex and 8mm open end wrench, unthread the mounting bolts. Run the bolt the nut onto the back of the bolt and snug tight with the 4mm and 8mm wrenches. (Fig. 7)

13. Check that the fender and light are level and straight and tighten the fork arch mounting bolt using the 5mm hex wrench. We will tighten the struts after installing the front wheel, which is up next.

14. Remove the plastic dropout protector from the metal shipping axle.

15. Unscrew and remove the metal shipping axle from the fork dropouts. You can discard or save this device in case you ship or transport your bike with the front wheel removed. Suggest you inflate the tire to make centering the wheel in the fork easier (point 4 below).

16. Loosen the axle nuts on the front wheel. Lift the front of the bike and insert the front wheel into the fork dropouts (a helper can make this easier). Insert the tab of the safety washers into the small holes on the outside of the fork dropouts (some suspension forks to not have a hole. For these make sure the nut is fully seated in the dropout reses.

17. Inspect the wheel to make sure it is centered in the fork. Tighten each axle nut a little at a time (17mm or adjustable wrench), alternating between sides until each axle nut is properly tightened.

18. Step 3: Seat Assembly (Refer to Fig. 8)
    3.1 – Assembling the Saddle onto the Seatpost:

19. Loosen the seat clamp nut.

20. Insert the seat post into the seat against the seat clamp limit and seated into the rails of the saddle.

21. Re-tighten the seat clamp nut (hand tight).

22.  Insert the seat post into the frame seat tube and rotate the saddle until the top of the saddle is level to the ground. You after Step 3.2. Do not sit, or test saddle until completing Step 3.2 WARNING! The seat post must be inserted into the seat tube at a depth where the minimum insertion line is not visible!
    Inserting the Saddle/Seatpost Assembly Into the Frame Seat Tube, Quick- Release Seatpost Clamp:
    

23. Open the seat post quick release lever (Fig.9). Apply a small amount of depth so that the minimum insertion line is no longer visible. NOTE: The lever should require some force to close. If it closes too easily and does not hold the clamping force by loosening or tightening the adjusting nut on the side opposite the lever.
    quick release lever. The tightness of the lever is adjusted by rotating the adjustment nut opposite the quick. Turn the nut by hand to adjust the tension while holding the lever stable.
    

24. Step 4: Handlebar & Handlebar Stem Assembly (Refer to Figs. 10 & 11)
    The handlebar has been pre-assembled together with brake levers, shifter levers shorter cable to the left (front brake). (NOTE: In some areas, such as the UK, the cables are required to be arranged in the opposite way).

Adjustable stem, a standard quill stem, or a threadless stem (Refer to Fig. 10). Regardless of stem type, always check that all the bolts are tight before riding. Respect the stem type and follow the instruction below:

1. For Quill Stem: Insert the handlebar stem into the fork steer tube to the minimum height line that is marked on the side of the handlebar stem. It may be necessary to loosen the stem Expander Bolt so that the stem can slide into the fork tube, until you get your desired height of the handlebar stem. For Threadless Stem: Slide the stem over the fork steer tube.
2.  Align the handlebar stem with the front wheel (See Fig. 11). Securely tighten the stem bolt(s). Note: Some models require a 6mm hex key. (Tightening torque: 18N.m or 14foot lbs.torque).
3. positioning the Handlebar:
   • Loosen the stem handlebar clamp bolt (Quill) or hex bolts (Threadless).
   • Position the handlebar at the desired angle. Make sure the handlebar is in the center of the stem handlebar clamp.
   • Tighten the handlebar clamp bolt (tightening torque: 18N.m or 14footlbs.lbs).
4.  Be sure that your handlebar and stem assembly is properly tightened before riding. The handlebar and stem should not rotate in the stem up or down or in the fork.
   

Step 5: Installing Pedals (Refer to Fig. 12)
The pedals are marked with either a “R” (Right) or “L” (Left) on the threaded end of the pedal axle.
Screw the pedal marked by” R” into the right side of the crank assembly (chain side of bicycle). Turn the pedal (by hand) in the clockwise direction. Tighten securely with a 15mm open-end, 15mm pedal specific wrench, or adjustable wrench (tighten to torque: 34N.m or 26 lbs.).
Screw the pedal marked by “L” into the left side of the crank assembly. Turn the left pedal (by hand) in the counterclockwise direction. Tighten securely with a 15mm open- end, 15mm pedal specific wrench, or adjustable wrench (tighten to torque: 34N.m or 26 lbs.).

Pedal Identification

Step 6: Brake Adjustments
The brakes on your bicycle should be correctly adjusted from the factory. However, it’s important to check the function of your brakes before your first ride. The following instructions are not exhaustive. We strongly suggest you take
your bike to your place of purchase, professional bike shop, or certified e-bike mechanic for assembly, adjustment, and maintenance.

Basic Disc Brake Adjustment
The following instructions are not exhaustive. We strongly suggest you take
your bike to your place of purchase, professional bike shop, or certified ebike mechanic for assembly, adjustment, and maintenance.

A. Brake Lever and Brake Pad Travel Adjustment
You can adjust the amount of braking leverage by adjusting the brake lever travel and by the closeness of the brake pads to the brake disc.

Brake Lever/Cable Adjustment
To adjust the travel of the brake lever, loosen the Locking Collar A1 (away from lever body), turn/unscrew the Adjusting Barrel A2 (what the cable enters) left/counterclockwise which tightens cable tension and increase lever travel & leverage, this will bring the caliper brake pads closer to the disc (Fig. 13).
If the pads are rubbing against the disc, reverse the process. If you have tuned the Adjusting Barrel to its maximum and the lever travel is still excessive you will have to adjust the space between the pads and the disc. Tighten the Locking Collar up to the lever body.

Once the correct amount of travel has been reached, center the brake Caliper on the disc by adjusting screw C (Fig. 14). When the brake pads are centered on the disc the wheel should spin freely with no rubbing. Upon applying the brake(s), there may be a slight amount of noise until the pads “bed” in, this should stop after your first ride.
Make sure there is no oil or grease on your hands or on the disc which can degrade brake performance.

• Checking Brake Pad Wear, Pad Replacement

• Pads that are 1mm thick (or less) need immediate replacement (Fig. 15).

• To install new pads, remove the brake caliper from the fork or frame by unscrewing hex bolts D (Fig. 16). Unscrew (left/counterclockwise), the smaller hex bolt inside hex bolt B (Fig. 17). Lift up and pull the inner pad downward, using the protruding tab. Slide a thin slot screwdriver under the outer pad and lift it up. Hold the screwdriver in this position and remove the pad with a pair of long-nosed pliers.

• Remove the springs from the worn-out pads and fit them onto the new pads. Replace the new pads, keeping them slightly inclined into the seat of the Caliper.
  Check that the spring hooks correctly onto the small piston. (When pulling downwards the pads should not come out). Refit the Caliper to the fork (or frame for rear brake).

• Turn adjuster screw C (Fig. 14) until the pads are centered on the disc and the wheel spins freely. Again, there may be some noise from the brake until it “beds” in. You may have to adjust the cable tension and lever adjustment –
  follow previous Step A. Brake Lever and Brake Pad Travel Adjustment.

• We strongly advise you have your brakes periodically checked and maintained by your dealer or a professional bicycle mechanic.

Step : Derailleur Gears Maintenance and Adjustment
The gears/derailleur(s) on your bicycle should be correctly adjusted from the factory. However, as cables do seat and stretch, it’s important to check the function of your shifting after your first ride. Note that it’s not unusual for your shifting system to need some adjustment after being used a few times.

We strongly recommend you have your e-bike serviced by your dealer or professional bike shop/mechanic.
To ensure long life and efficiency for your drivetrain system, it must be kept clean and properly lubricated. Before attempting any adjustments, make sure you understand the drivetrain components functions and feel confident to attempt such maintenance.

•  Left shifter controls the front derailleur and chain wheel(s); Right shifter controls the rear derailleur and rear cogset.
• The largest/larger rear sprockets on the cogset are the low [speed] gears used for hill climbing and low speed technical riding; the smallest/smaller rear cogs are for cruising and high(er) speed and downhill riding.
• NOTE: For good shifting and riding experience, follow these 4 actions:

1. Shift only when pedaling (forward), do not shift when stopped.
2. Do not use hard, aggressive pedal pressure while changing gears.
3. Never back pedal when changing gears.
4. Never force the gear shifting levers.

• Rear Derailleur Adjustment
  There are two limit adjustment screws on the rear derailleur – High/”H” and Low “L”. Looking from the rear of the bike forward, the limit adjustments center the chain on the high/large and low/small rear cogs which prevents the chain from going over the large cog and into the wheel/left (the “H” or high adjustment screw) or into the frame/ right (the “L” or low adjustment screw).

First, the derailleur cable tension needs to be correct
Position the shifter(s) so the chain is on the smallest rear cog and largest front sprocket – check for cable slack at point “B” (Refer to Fig. 18). If there is slack, loosen the cable nut or hex bolt, pull the cable with pliers and retighten the cable nut/bolt while pulling cable taut (tightening torque: 5-7N.m or 4-5 lbs.)

High/Large Cog (“H”) Limit Adjustment
Turn the “high limit” adjust screw marked “H” on the rear derailleur so that, again looking from the rear, the upper guide pulley is below the vertical plane of the center of the top/large cog.

Low/Small Rear Cog (“L”) Limit Adjustment
Turn the “low limit” adjust screw marked “L” on the rear derailleur so that, again looking from the rear, the upper guide pulley is below the vertical plane of the center of the low/small cog.

1. Operate the shift lever to shift the chain from top gear to 2nd gear.
   • If the chain will not move to the 2nd gear, turn the cable adjusting barrel on the rear derailleur to increase the tension (counterclockwise)
   • If the chain moves past the 2nd gear, decrease the tension (clockwise)
2. Next, with the chain on the 2nd gear, increase the inner cable tension while turning the crank forward. Stop turning the cable adjusting barrel just before the chain makes noise against the 3rd gear. This completes the adjustment. Make sure the drivetrain is clean. We suggest “dry” lubricants for most applications.

Step : Check Before Riding

Make sure the wheels are tight and secure. Tighten the front and rear hubs nuts securely. (Tighten torque: about 30N.m for front wheel, about 25 to 30 Nm. for rear wheel).
For Quick-Release (QR) hubs/axles, make sure the QR levers are in the locked/closed position. Before riding, lift the front of the bicycle so that the front wheel is off the ground, lightly bounce it to the ground and give the top of the tire a few downward strikes. The wheel should not wobble or come off and there should be no rattling. Do the same for the rear wheel.

• As with the battery, hub, display and other electrical parts – Never strongly shake, slam/drop, or throw the Controller – damage is likely.
• As with the battery, the best operating temperatures for the controller is: 5F-104F (-15°C to +40°C).
• The controller should be used in normal working temperature range from -15°C to +40°C.
• WARNING! NEVER open the controller box. Any attempt to open the controller box, modify or adjust the controller will void the warranty. Please ask your local dealer or authorized service specialist to repair your bike.
