should be chec ed and ad usted fre uently to eep the transmission parts e ible without impact sound and
noise Chec the screws and nuts of the bicycle, 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.
Note that the tightening tor ue of front wheel, handlebar core screw rod, saddle pipe clamping Bolt and
saddle clamping Bolt shall not be less than18N.m The tightening tor ue of rear wheel, bottom brac et Cup
and bottom brac et Cup loc nut shall not be less than 30N.m
4.The bra ing part should be chec ed and ad usted fre uently to ma e it in a e ible state, for e ample, the gap
between the bra e rubber and the gate core should not be too large.

Correct use and maintenance methods of motor, controller and battery:
1.The motor should be ept clean, no foreign matter, corrosive li uid, gas, etc. should enter the motor, and the
motor hell should not be noc ed and ba ed to avoid damage to the motor.
2. All wires should avoid friction and contact with sharp metal, and the wires should be tied rmly 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.
battery should be stored after su cient electricity, and the electric energy should be replenished regularly to
avoid battery vulcani ation caused by long-term under power.
5.The battery cannot be near open ame or high temperature heat source, and the battery cannot be thrown
