Warning: As with all mechanical components, the bicycle is subjected to wear and high stresses. 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 form of crack, scratches or change of coloring in highly stressed areas indicates that the life of the component has been reached and it should be replaced.
Warning: It is important to use only genuine replacement parts for several safety-critical components.
4.1To keep the electric bicycle functioning well, the following routine maintenance and lubrication is necessary for you.

• Half Yearly – Remove and clean, lubricate the chain, derailleur gears and all cables. Check and replace as required.
• NB – Wash cycle weekly with warm soapy water and dry it by rubbing with a soft cloth.
  Warning: When the rim becomes part of the brake system, it is very important to check the rim wear monthly and adjust the brake shoes accordingly to make the clearance at 1-1.5mm from the track of rim. The wear of rim may destroy the braking and result in personal injury to the rider or others.

Assembly Instruction

Here is some important information for electric bicycle assembly, which is very useful for your maintaining your electric bicycle, and especially helpful when you purchase our e-bikes which is partly assembled and packed in a carton.
Step 1: Preparation:
Take the electric bicycle and parts out of the carton and detach all parts that are tied to the frame. Be careful not to scratch the frame or cut the tire when removing the wrapping. And please do not rotate the handlebar either until disassembly, otherwise, it may break the cables. Then carefully examine the carton for loose parts and make certain that no parts are left.
Step 2: Seat Assembly (refer to fig.4)

1. Loosen the seat clamp nuts(both sides)
2.  Insert the seat post into the seat clamp. The seat post must extend at least 1/4 inch(6-7mm) above the top edge of the seat clamp.
3. Re-tighten the seat clamp nuts on both sides(hand tight).
4. Push the seat post into the seat tube of the electric bicycle frame and rotate the seat until the tip of the seat is directly above the top tube of the fra me.THE SEAT POST MUST BE INSERTED INTO THE SEAT TUBE AT A DEPTH WHERE THE MINIMUM INSERTION LINE IS NOT VISIBLE!!!
5. Open the seat post quick release lever(Fig. 5). Insert the seat post into the seat tube to a sufficient depth so that the minimum insertion line is no longer showing.
6.  When you are satisfied with the height of the seat post, close the sea post quick release lever. The tightness of the lever is adjusted by rotating the adjustment nut opposite the quick release lever. Turn the nut by hand to adjust the tension while holding the lever stable.
   Step 3: Handlebar & Handlebar Stem Assembly(refer to fig. 6 and 7)

•  As a usual situation, in our factory, the handlebar has been pre-assembled together with brake levers, shifter levers and grips. Be sure that the longer cable is fixed to the right lever (rear brake) and the shorter cable to the left (front brake), or according to your local rule and practice (Note: In some area, such as UK, the cables are required to be arranged in the opposite way).
• Since your cycle may be fitted with an adjustable, a standard stem or an A-head stem(refer to fig.6 ), you must always check that all the bolts are tight before cycling. Based on the situation of the standard handlebar stem, please follow the instruction below:

1. Push the handlebar stem into the fork tube (head of the frame ) to the minimum height line that is marked on the side of the handlebar stem. It might be necessary to loosen the expander bolt so that the stem can slide into the fork tube, until you get your desired height of the handlebar stem.

2. Align the handlebar stem with the front wheel(see fig.7). Tighten securely the expander bolt with an adjustable wrench.
   Note: Some models require a 6mm allen key.(Tightening torque: 18N.m or 14 foot lbs.torque)

3. Loosen the handlebar clamp bolt and nut from the stem.

4. Position the handlebar at the desired angle. Make sure that the stem is in the center of the handlebar

5. Tighten securely the handlebar clamp bolt (Tightening torque: 18N.m or 14 foot. lbs)

6. Be sure that your handlebar and stem assemblies are properly tight before riding. The handlebar should not rotate in the stem. When you straddle and grip the front wheel between your knees, the handlebar should not be able to turn when you apply pressure horizontally. Refer to (fig. 7).
   Note: Under the situation of the A-head stem, you make a similar operation as the above. Compression bolt tightening torque: 23N.m or 17 foot lbs. torque; stem clamp bolt tightening torque: 12N.m or 9 foot. Lbs

Step 4 Attaching Pedals(refer to fig. 8) :

1. The pedals are marked with either a “R” or “ L” on the threaded end of the pedal axle.

2. Screw the pedal marked ”R” into the right side of the crank assembly (chain side of electric bicycles).
   Turn the pedal (by hand) in the clockwise direction. Tighten securely with an adjustable wrench or the plate wrench special for pedals(Tightening torque: 34N.m or 26foot.lbs).

3. Screw the pedal marked “L” into the left side of the crank as semble. Turn the left pedal (by hand) in the counterclockwise direction. Tighten securely with an adjustable wrench or the plate wrench special for pedals(Tightening torque: 34N.m or 26foot.lbs)

Step 5 Front wheel installation：

1. Cut the wrapping rope, remove the front wheel, and remove the front fork protection lever and the front wheel protection cover.
2. Make sure that the front wheel is in line with the rear wheel, then start the installation. First, pull the wheel upwards, put the disc brake pad into the front brake caliper, and then use 15 wrenches to tighter the front hub fixing screw.
3. Adjust the adjusting screw of the disc brake to make the disc brake rotor without obvious friction

Step 6 Brake Adjustments:
The brake on your electric bicycle should have been adjusted correctly in our factory, however, as cables do stretch, it is important to check the adjustment of your brakes after your first riding. Most brakes will need some adjustment after being used a few times.
6.1 Basic Disc Brake Adjustment
The notes that follow are not exhaustive. If you need further assistance, please take your cycle to your local dealer or a professional cycle shop.
a. Brake Lever and Brake Pad Travel Adjustment

• You can alter the amount of braking pressure by altering the travel of the brake lever and by the proximity of the brake pads to the brake disc.
• To alter the travel of the brake lever adjust screw A (see fig. 9), unscrew screw A reduce the amount of lever travel and by tightening it increases the lever travel. If you have fully unscrewed screw A and the lever travel is still excessive you will have to adjust the space between the pads and the disc.
•  Tighten screw A (Fig.9) up to the brake level. Go to Fig.11 and insert an allen key into the smaller hole inside allen key hole B. Rotating the allen key clockwise pushes the outer brake pad forward by approx.0.8mm After each turn, check the braking performance.
• Once the correct amount of travel has been reached, centre the brake Calliper on the disc by adjusting screw C(Fig.12).when the brake pads are centered on the disc the wheel should spin freely, though there may be a slight amount of noise until the pads “bed” in.
• If your cycle came from, or has recently been overhauled by a professional repair shop. you should be able to maintain good braking performance by adjuster screw C (refer to Fig.12)
• Once the correct amount of travel has been reached, center the brake caliper on the disc by adjusting screw C (fig.12). When the brake pads are centered on the disc the wheel should spin freely, though may be a slight amount of noise until the pad bed in. b.Brake pad wear and replacement
• When you check your brake pads due to falling performance, check their thickness. If they are less than 1 mm (Fig. 13), they will need replacing.

• To fit new pads, remove the brake caliper from the fork or frame by unscrewing Allen bolts D(Fig.14). Unscrew (anti-clockwise), the smaller Allen bolt inside Allen bolt B(Fig.11). Lift up and pull the inner pad downward, using the protruding part. 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 and adjuster screw C(Fig.12)until the pads and the disc are centered and the wheel spins freely. Again there may be some noise from the brake until it “bed” in.

Step 7 Derailleur Gears Maintenance and Adjustment
To ensure that your derailleur gear works efficiently and to prolong its life, it must be kept clean and free from excessive dirt built up and should be properly lubricated.
Note: If the specific instruction manual is provided accompanied by your bike, please follow it.

Before Adjustment, please make sure of the following details:

• The right shifter controls the rear derailleur and sprocket.
• The largest rear sprocket generates low gear for hill climbing; the small rear gear sprocket develops high gear ratios for speed work and downhill riding.
• The small chain ring produces low gear ratios while the larger front chain ring produces high gear ratios
• To operate your derailleur gear system efficiently and reduce damage, wear and reduce noise to a minimum, avoid using the maximum crossover gear ratios of large  chainring/large rear sprocket, small chain ring/small rear sprocket

Note: For positive gear selection, observe these four precautions

1. change only when pedals and wheels are moving in a forward motion
2. reduce pedal pressure while changing gears
3. Never backpedal when changing gears
4. Never force the gear levers

7.1Rear Derailleur Adjustments:
Move the shifter all the way forward (toward the seat) and with the chain on the smallest rear sprocket and largest front sprocket, check for cable slack at point “B”. If there is slack, loosen the cable nut or screw, pull on the cable end with pliers, and retighten the cable nut or screw while pulling the cable taut(tightening torque: 5-7N.m or 4-5foot.lbs)
7.2 Top Adjustment
Turn the “H” adjusting screw(or top rear adjustment screw) on the gear mechanism so that, looking from the rear, the guide pulley is below the outline of the top gear.

7.3 Low Adjustment

• Turn the “L” adjusting screw (or low gear adjustment screw) so that the guide pulley moves to a position directly below the low gear.
• operate the shifting 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 to increase the tension 1(counterclockwise).
• If the chain moves past the 2nd gear, decrease the tension 2(clockwise)
• 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 Be sure to perform oil maintenance at each part of the transfer mechanism. The optimum oil is dry molybdenum oil or the equivalent.

The back derailleur :

Step 8: Tighten the front and rear hubs nuts securely.(Tighten torque: about 30 N.m for the front wheel, about 25 to 30 N.m for the rear wheel )Before riding, lift the front of the bicycle so that the front wheel is off the ground and give the top of the tire a few sharp downward strikes. The wheel should not wobble or come off
Step 9 Tire inflation instruction:
9.1 After the bicycle is assembled, please check whether the air pressure of the front and rear tires is within the normal value.
9.2 When refilling tires, you must refer to the inflation reference range on the side of the tire for refilling, generally between 20PSI (140Kpa).

SECTION II MANUAL FOR ELECTRIC PART

The model instructed in this manual is made with “start aid”. This electric assistance system will help riders to save their energy, while they enjoy their easy sports.
Here is the function of the so-called “smart aid”: when you long press the down button for display for seconds, the bike can be started at speed of 6 km/h. After the bike moves forward, you can easily pedal on and release the “start aid” button.
Also, you can pedal 3/4 round of the chain wheel to start the motor without using the “start aid” button.
