As an usual situation, in our factory, the handlebar have 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 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 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 assembles 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 A-head stem, you make the similar operation as the above.

Step 5 Front wheel installation：
1）Cut the wrapping rope, remove the front wheel, 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 installation. First pull the
wheel upwards, put the disc brake pad into the front brake caliper, and then use 15 wrench 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 follows 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.

9
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 increase 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.
Fig.9 Brake Lever Adjustment
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.
B
smaller keyhole inside main hole
Fig.11 Disc brake pad adjustment Fig 12 Disc brake pads adjustment
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.
Fig.13 Fig.14
C

10
To fit new pads, remove the brake calliper from the fork or frame by unscrewing allien bolts D(Fig.14).
Unscrew (anti-clock wise), 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 with 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 generate low gear for hill climbing; the small rear gear sprocket develop high
gear ratios for speed work and downhill riding.
The small chain ring produce low gear ratios while the larger front chain ring produce 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 chain ring/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 back pedal when changing gears
4) Never force the gear levers
7.1Rear Derailleur Adjustments:
Move the shifter all the way forward (toward 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 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.

11
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(counter
clockwise).
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 make noise against the 3rd
gear. This complete 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 front wheel, about
25 to 30 N.m for 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).
