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

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

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.
