Does this product fit your bike?
Check the model, battery voltage, motor connector and matching display. Connector colour alone is not sufficient.
Use and operation
The controller manages electrical operation between the battery, controls and motor. The correct type depends on the bike’s configuration and connected components. Compare connectors and label specifications as well as the model name.
Preparing for installation
Have the correct version, product information and suitable tools ready before starting. Check the new part before removing the old one. Take photos of the existing mounts and connectors if needed.
What should I check when installing it?
Disconnect power and have a technician check the connections if unsure. After installation, check assistance and brake cut-off operation.
Checks after installation
Check the mounting and operation before using the bike again. If there is play, rubbing, an error message or unusual operation, stop and have the cause checked.
Care and checks
Keep cables free from pinching and secure the controller in its intended position. Check connectors for moisture, damage and loose contacts. Recurring faults require diagnosis; connecting a different controller at random is not a targeted repair.
