RECOMMENDATIONS AND MAINTENANCE
6.3 Troubleshooting
How do I know how much charge my battery has when it is not connected to the bike?
● By pushing the power button on the battery, LEDs will light up, indicating the remaining capacity.
How can I test my battery capacity?
● Please contact NCM to arrange the return of your battery for testing. If the battery tests above 85% capacity within the
first year (from purchase date) you will be liable for return freight. If it is tested and is under capacity within the warranty
period, your battery will be replaced.
What happens if my battery goes empty while I’m riding my E-bike?
● Assistance will stop when only 1 bar remains on the indicator. Your E-bike can still be ridden without assistance.
Should I always empty my battery completely before recharging?
● There is no need to do a complete discharge every time. We recommend doing a complete discharge every 2-3 months.
What should I do if the rim has a buckle or spokes coming loose all the time?
● Take your bike to a qualified wheel builder or technician for service. The issue may be as simple as adjusting the spoke
tension.
My display turns on, but the motor does not activate. What should I do?
● Check the motor plug from the controller. This is a very stiff connection and will not work unless the plug is all the way in
to the indicator line. The twisting of the handlebar can sometimes cause the plug to pull out slightly if there is not enough
slack in the motor cable.
The display won’t turn on unless the battery charger is plugged in?
● Please refer to the display manual for error code definition and if needed, report the error code to NCM.
How come competitors’ motors make a different sound?
● NCM uses a different internal structure than some competitors. As a consequence, we have a slightly higher frequency
and better torque.
