Battery fault
Battery voltage loss
The battery cannot get charged(The charger green light on)
Even if the customers had not ridden the bike for a long time, the battery should be charged one
time in sixty days to avoid the battery voltage loss. The original charger cannot be used to charge
the battery when the battery voltage is lower than the charger voltage.
The battery voltage loss can lead to the failure to charge the battery through the original charger.
The customer needs to look for a lower voltage charger to charge the battery. For instance,
the customer can try to charge 48V battery deeply one time by 36V charger till the red light turn
to green light, then continuing to charge by original 48V charger to see whether red light of the
charger is on. The issue will be solved after the light turns green. If the issue cannot be solved,
the customer should replace a battery.
Endurance mileage decrease
The battery gets charged fully in a few minutes, but running out shortly. The endurance mileage
is much less than described, which can be caused by the protective board or electric core fault.
The customer should replace the battery to local bike shops staff for help if they fail to do
adjustment.
The battery stops working when the bike climbing
The battery always stops working when the bike goes up the hill, but works normally on flat roads.
This can be caused by the protective board or electric core fault. The customer should replace the
battery.
Motor fault
Charger fault
The display shows error code , which means the motor stops working because the Hall sensor
got burned, or motor overload got burned, or motor gear got damaged with noise. The customer
should replace the motor.
Notice: The customer should check whether the wires loose, the function buttons are in the normal
place.
The customer should rule out the problem caused by controller and display before checking the motor
The red light of charger will be on when charging, while the green light will be on when it stops
charging. The normal charging time is 4 to 6 hours.
