Note: This controller is designed for specific models (Kugoo Kukirin M4 / M4 Pro). Using it with incompatible models may result in damage or malfunction.

5. Operating Instructions

The SPEDWHEL Controller functions as the central processing unit for your electric scooter. Once correctly installed, its operation is integrated with the scooter's existing systems (e.g., display, throttle, brakes). There are no direct user controls on the controller itself.

  • Ensure all connections are secure and correct after installation.
  • Operate your scooter according to its original user manual.
  • The controller will manage power delivery to the motor based on throttle input and regulate battery usage.
  • Brake inputs will signal the controller to cut power to the motor.

If the scooter exhibits unusual behavior after controller installation, refer to the troubleshooting section.

6. Maintenance

Proper maintenance ensures the longevity and reliable performance of your SPEDWHEL Controller.

  • Keep Clean: Periodically inspect the controller and its housing for dirt, dust, or debris. Clean with a soft, dry cloth. Avoid using liquids directly on the controller.
  • Check Connections: Regularly inspect all wiring connections to ensure they are tight and free from corrosion or damage. Loose connections can lead to intermittent power or malfunction.
  • Avoid Moisture: While the controller has an aluminum exterior, it is not fully waterproof. Protect it from heavy rain and submersion to prevent internal damage.
  • Temperature Control: Ensure the controller is not exposed to extreme temperatures for prolonged periods, as this can affect its electronic components.
  • Physical Damage: Avoid impacts or physical damage to the controller's housing.

7. Troubleshooting

If you encounter issues after installing the SPEDWHEL Controller, consider the following troubleshooting steps:

  • Scooter Not Powering On:
    • Check battery connection and charge level.
    • Verify the main power connection to the controller.
    • Ensure the display unit is correctly connected.
  • Motor Not Responding / Erratic Behavior:
    • Inspect all motor phase wires and hall sensor wires for secure connections.
    • Check throttle connection and functionality.
    • Ensure brake lever sensors are not stuck in the 'engaged' position.
  • Error Codes on Display:
    • Refer to your scooter's original user manual for specific error code meanings.
    • Common error codes often relate to motor, hall sensor, or throttle issues.
  • Overheating:
    • Ensure the controller is not obstructed and has adequate airflow.
    • Avoid prolonged heavy loads on the scooter.

If these steps do not resolve the issue, it is recommended to consult a professional electric scooter repair service or contact SPEDWHEL customer support.
