Electrical System (Throttle/Display/Cutoff)

Electrical System Features

The front and rear brake levers contain safety power cutoff switches, which disable the hub motor’s assistance when applied. Both levers should be checked for correct operation. The throttle should provide smooth acceleration when gradually applied. If the throttle, brake lever cutoff switches, pedal assistance, or lighting are functioning abnormally, intermittently, or not working, please discontinue the use of your ebike immediately and contact the Fission Cycles Support team for assistance.

Error Detection

Our bike from Fission Cycles is equipped with an error detection system integrated into the display and controller. In the case of an electronic control system fault an error code should display. The following error codes are the most common and can aid in troubleshooting. If your bike has an error code displayed at any time it is recommended that you cease operation and contact Fission Cycles immediately.

Error Code Definition: 

  • 21 Abnormal Current

  • 22 Throttle Fault

  • 23 Motor Phase Fault

  • 24 Motor Hall Fault

  • 25 Brake Switch Fault or Brake Applied While Turning On

  • 26 Under-voltage Protection

  • 30 Communication Fault

The electrical system powers several components on your ebike that control different operating conditions and user preferences. It is critical that you familiarize yourself with all aspects of your ebike’s electrical system and check to see if it is working correctly before every ride.

 If you are not confident in your ability to successfully and safely perform all steps, we recommend having the work performed or checked by a local, certified, and reputable bike mechanic.
