6 Problem with
the display
German /
If there is moisture inside the display, first place
the bike in the sun for a while. If it still does not
work, you will need to replace the display. We
can provide spare parts.
1. Check if the display parameter value is the
default value.
2. If the display parameter value is normal, turn
on the display and long press the "-" button to
check if the 6km/h boost is working. If it is
working, replace the boost sensor. If it is not
working, you also need to check if the display
shows the speed value by idling the pedal. If the
speed value is displayed, you need to replace
the controller. If the speed value is not
displayed, you need to replace the display.
Note: Display failure requires more detailed
judgment to confirm. We recommend that you
contact the seller to solve this problem.
Problem with the display
1. The display does not show any speed/mile-
age -> plug
the motor connector back in. If it still does not
work, replace the motor.
2. The display switches off while driving, then
switches on again and stays on and cannot be
switched off. -> Replace the display.
3. The battery shows full charge, but the display
shows empty charge and flashes constantly. ->
Check the parameters. If it still does not work,
change the display.
