Precautions before riding
Dear users, for your safety and to prevent safety accidents, please do the following checks before
riding. If there is any abnormality，please repair it in time or find a professional repair!
(1)Inspection of power supply circuit and lighting circuit:
Check whether the power supply circuit, lighting circuit and device are damaged; Turn on the
power supply, operate the lighting switch, check whether the headlights and taillights are on, and
whether the brightness of the headlights and taillights is normal;
Check the front and rear brake handlebars respectively to check whether the stop lamp is on
and whether the motor is powered off;
Operate steering lamp switch to check whether the steering indicator and turn signal are
working properly.
(2)Check of brake device:
Check whether the front and rear brakes can work normally; Check the braking effect of the
front and rear brakes to ensure that the brakes are normal and effective;
Confirm whether the power-off switch is normal when the rear wheels are off the ground with
double support of the whole vehicle;
Please check the fastening status of each axle to ensure that the front and rear axles and
handlebars are fastened reliably.
(3)Check the fastening status of handlebar and front and back wheels:
Shake the handlebar up, down , front, back, left and right to check whether it is loose or
pongee;
Shake left and right front and back wheels to check whether there is looseness; whether the
rotating wheel is too tight or stuck.
(4)Tire inspection:
Check whether the tire pressure is normal. Judge whether the air pressure is appropriate
according to the depression of the ground part of the tire. When the air pressure is abnormal, use
the tire pressure measuring instrument to check and adjust it to the normal air pressure;
whether the tire has cracks or abnormal wear;
Whether the tire is embedded with nails, stones and glass;
When the tire is used to the tread wear mark, the tire should be replaced.
(5)Inspection of reflector and license plate:
Check whether the reflector is missing. If it is found missing, contact the after-sales service
immediately to reassemble the reflector of the same specification and model, and the installation
position should be consistent with the original bicycle .Please do not change the position, modify,
disassemble, etc. privately.
Before each use, check that the function of the reflector is normal and the surface of the
reflector is kept clean.
The Reflector device cannot be blocked by luggage, children chair, clothes and other objects,
otherwise it will cause potential safety hazards.
Check whether the license plate is installed firmly, whether the number is clear, whether there
is any damage or pollution, and if there is any should, reinforce, clean or replace it in time.
Before each ride, please make sure that the following items: whether the frame lock，vertical
tube lock, seat tube locking fastener are locked, whether the brake system is normal, and the
tires are full of gas to ensure riding safety!

Adjustment methods of each part
I.Adjustment of front and rear brake system: (the adjustment method of front and rear brakes is
the same)
1.The rear integrated disc brake(see figure 1); Adjust the upper and lower nuts of the disc brake to
make the spacing between disc brake and brake caliper 1.5-3mm, adjust the height of disc brake,
and then tighten the nuts.
2.Front integrated disc brake (see figure 2): Adjust the A and B nuts of the disc brake and adjust the
height of the disc brake so that the distance between the disc brake and the caliper is 1.5-3mm. If
the distance is deviated, use the C screw to adjust, and then tighten the nut.
Rotate the Adjusting nut to rotate the Adjusting nut forward, the brake becomes tight, otherwise it
becomes loose. When adjusting, hold the brake handle at the same time, so that when the position
of the brake handle is 1/3 of the total stroke, the brake rubber block can be tightly attached to the
brake drum. (See figure 3)
3.Disc brake: (see Figure 7 and 8)
Key points of disc brake adjustment: there is enough clearance between disc brake and brake pad
(there is no interference between the brake disc and the brake skin when rotating, and the best
braking effect is appropriate) adjust the nut, lengthen about brake cable, check whether the brake
handle has been adjusted to the appropriate tightness; Then test ride to ensure effective and
normal braking.
II.Chain adjustment (see figure 4)
1.Loosen the rear axle left and right fastening nuts, adjust the chain regulator, move the rear
wheels back and forth, and tighten the tightness of the chain so that the sag in the middle of the
chain is 10-15mm.At this time, the tightness of the chain should be suitable for go slick, no
abnormal sound.
2.Keep the center surface of the rear wheel basically in the center surface of the frame, and tighten
the rear axle left and right fastening nuts. (Recommended torque is not less than 30N.m)
III.Front wheel disassembly (see Figure 5)
1.Loosen the left and rear fastening thread of the front axle, remove the nut, remove the front
axle, and remove the front wheel.
2.When assembling, align the center hole of the front wheel with the double arm hole of the
hydraulic front fork, penetrate the front axle into the hole, and tighten the left and right fastening
nuts of the front axle clock wise. After installation, rotate the front wheel, and there shall be no
stuck or loose phenomenon. (The recommended torque is not less than 18N. m)
IV.Rear wheel disassembly (see Figure 6)
1.Pull the motor cable off the connector, turn the car body over(note: Do not touch the handlebar,
head cover, toolbox parts), rotate the rear axle nut, rear brake positioning nut and brake cable in
the counterclockwise direction, unpack the chain joint, and then remove the rear wheel in the
direction of the opening.
Note: To ensure driving safety, brake rubber the working face is worn to 1/2 of brake rubber,
a new brake rubber should be replaced.

Maintenance and Repair
Daily maintenance:
1.The vehicle should be kept clean and clean, and the vehicle should be wiped with dry cloth in
time after being drenched to avoid rusting of parts and short circuit of electrical components.
2.Always check the air storage capacity of the tire to keep it in normal use.
3.The main transmission parts such as front axle, a roar axle, conter axle, front fork, Flywheel and
electric hub should be checked and adjusted frequently to keep the transmission parts flexible
without impact sound and noise; Check the screws and nuts of the whole car, if it is found that it is
loose, it should be tightened in time to prevent the parts from being worn out or causing greater
damage and fracture due to looseness.
4.The braking part should be checked and adjusted frequently to make it in a flexible state, for
example, the gap between the brake rubber and the gate core should not be too large.
5.Always check whether the operating parts and cable are flexible, and ensure that there is no
stagnation, no stagnation, and properly drip lubricating oil from one end of the hose slowly, and
pull the wire rope at the same time, feel that the wire rope slides lightly in the hose.
6.Electric bicycle moving parts should be often injected with a small amount of lubricating oil to
reduce wear and keep riding light, as shown in the following table:
Correct use and maintenance methods of motor, controller and battery:
1.The motor should be kept clean, no foreign matter, corrosive liquid, gas, etc. should enter the
motor, and the motor Shell should not be knocked and baked to avoid damage to the motor.
2. All wires should avoid friction and contact with sharp metal, and the wires should be tied firmly
with the frame.
3.The controller is a high-tech intelligent computer memory program password. If the user opens
the repair by himself, the components will be easily damaged. If the controller fails, please go to
the service department to repair it.
4.This battery is a special battery for electric bicycles. When the electric bicycle is not used for a
long time, the battery should be stored after sufficient electricity, and the electric energy should be
replenished regularly to avoid battery vulcanization caused by long-term under power.
5.The battery cannot be near open flame or high temperature heat source, and the battery cannot
be thrown into the fire. Direct exposure to the sun is strictly prohibited in hot and hot weather.
