3. Opsætning og installation

The installation of the torque center axle sensor requires careful attention and specific tools. It is recommended that installation be performed by a qualified bicycle technician or an individual with experience in e-bike motor systems.

3.1. Kontroller før installation

• Ensure the sensor model is compatible with your Bafang M420, M500, or M600 mid-motor.
• Gather all necessary tools, including a BESST tool for recalibration.
• Disconnect the e-bike's battery before starting any work.

1. Carefully remove the existing central axle from your Bafang mid-motor. Refer to your Bafang motor's specific service manual for detailed removal instructions.
2. Insert the new SPORTARC Torque Center Axle Sensor into the motor housing, ensuring it is correctly seated and aligned.
3. Secure the sensor according to the motor's specifications.
4. Connect the sensor's cable to the appropriate port on the Bafang mid-motor. Ensure the connection is firm and secure.

3.3. Post-installation Recalibration (Crucial Step)

After replacing the central axle sensor, it is mandatory to use the Bafang BESST tool to recalibrate the new torque central axle and the motor. Failure to perform this recalibration will prevent the system from functioning correctly.

Consult the Bafang BESST tool manual for detailed instructions on the recalibration process.

4. Betjening

Once properly installed and recalibrated, the SPORTARC Torque Center Axle Sensor will provide power assist functionality to your e-bike. The sensor detects the force applied to the pedals and signals the motor to provide assistance proportionally, resulting in a natural and responsive riding experience.

• The level of power assist can typically be adjusted via your e-bike's display unit, if supported by your Bafang motor system.
• Ensure all connections remain secure during operation.

5. Vedligeholdelse

Regular maintenance helps ensure the longevity and optimal performance of your torque sensor.

• Rensning: Keep the sensor area clean from dirt, dust, and debris. Use a soft, damp cloth for cleaning. Avoid using harsh chemicals or high-pressure water jets directly on the sensor or motor.
• Inspektion: Periodically inspect the sensor and its cable for any signs of wear, damage, or loose connections. Address any issues promptly.
• Opbevaring: If the e-bike is stored for an extended period, ensure it is in a dry, temperate environment.

6. Fejlfinding

If you experience issues with your power assist system after installing the sensor, consider the following troubleshooting steps:

• No Power Assist:
  • Verify that the sensor cable is securely connected to the motor.
  • Confirm that the e-bike battery is charged and properly connected.
  • Crucially, ensure the sensor has been recalibrated using the Bafang BESST tool after installation. This is a common cause of non-functionality.
• Inkonsekvent Power Assist:
  • Check for any physical obstructions or damage to the sensor or axle.
  • Re-check the recalibration process with the BESST tool.
• Fejlkoder: If your e-bike display shows an error code, consult your Bafang motor manual or the BESST tool documentation for specific error code interpretations and solutions.

If problems persist after attempting these steps, contact a qualified e-bike technician or SPORTARC customer support for further assistance.
