Fault phenomenon
Analysis and solution
Motor
Front and rear
1. The motor does not work.
2. The motor is very hot.
1. The front and rear lights do
not illuminate.
2. The front and rear lights are
suddenly powered off during
riding.
1. Check whether the outgoing line of the hub motor is broken or
scratched.
2. Check whether the connection between the hub motor and the
controller falls off or is loose.
3. If the mid motor does not work, replace it.
1. Check whether the connection between the front and rear lights
and the controller is normal.
2. Check whether the outgoing lines of front and rear lights are
broken or damaged.
3. Replace the front and rear lights in case of any damage.
Confirm whether the riding is reasonable, and replace the motor if
it gets very hot during normal riding.
controller
1. Fault occurs during riding,
resulting in sudden stop and
failure to restart
2. The instrument is suddenly
powered off (turned off) when
the E-bike is started.
3. The engine crashes sudd-
enly after long-distance riding
1. The controller or motor Hall is burnt out due to current.
2. Restart to check whether there is any error code abnormality
reported by the instrument, and determine the fault cause according
to the abnormality.
The currents of the controller and battery do not match.
The controller current is greater than the battery BMS current,
resulting in power failure of battery protection. Replace the
controller or battery.
1. As the motor and controller get hot after long riding, the system
stops working. Replace the electronic control system.
2. Long riding leads to the current increase and automatic
protection of the system.
