1, human feeling of speed when riding slowly, Zhizhong strong sense of→ before and after adjustment (1) the front brake or brake (up gates) with the rotating parts of the friction brake and the rotating parts clearance, both to make the rotation flexibility, but also to ensure the brake ** can be good.
(2) the chain too tight → adjust rear axle front and rear position
(3) front and rear axle profile and axis components and cap too tight or worn parts, → loose fasteners, or replacement of worn parts.
(4) The front and rear tire under-inflated → tires inflated to the foot.
2, the battery is fully load conditions, the two red lights extinguished
(1) The charger output voltage is low → troubleshooting charger repair method.
(2) Battery charging time short → recharged to extend the charging time.
(3) The battery pack or single capacity decreased> battery box maintenance troubleshooting.
(4) electrode damage or poor contact → replace the electrode.
In motion to stop when the fast slowly, unable to feel
(1) seven pin connector poor contact → change the seven-wire.
(2) Hall power-off brake poor contact → change Hall power brake handle.
4, the battery is fully display full bright light load wheel rotation weakness
(1) gear wear slip → change gears.
(2) wheel hub motor winding part of the short circuit → Replace the motor.
(3) bicycle assembly problems or component wear → Replace the damping rubber.
5, power-driven irregular stall
(1) The controller and electric wheel connector is loose or bad electrical bike → re-seated the connector or replace the plug-ins.
(2) wheel motor carbon brushes troubleshooting → ??poor contact with the rotor wheel repair method.
6, the electric bicycle drive noise sound
(1) wheel gear short of oil → Open the wheels, coated with gear oil.
(2) gear defect → replacement gear.
(3) gear shell bearing damage → Replace bearings.
