3. Setup and Installation

The BAFANG mid-drive motor controller is a critical component for your e-bike system. Proper installation is essential for optimal performance and safety.

3.1 Controller Version Compatibility

BAFANG controllers come in different versions. It is crucial to identify your motor and controller version for correct replacement or installation.

• Old Version Controller: The physical size and internal components may differ from newer versions.
• New Version Controller: Some new version controllers may lack a speed sensor connection and a light plug. If your motor requires these connections and your new controller does not have them, you may need to order a compatible version.

Note: Before placing an order for a replacement controller, always verify the version of your existing controller to ensure compatibility with your motor.

3.2 General Installation Steps (Refer to your specific motor manual for detailed instructions)

1. Disconnect Power: Ensure the e-bike battery is completely disconnected before starting.
2. Access Controller: Carefully access the motor unit where the controller is housed. This may involve removing covers or other components.
3. Remove Old Controller (if replacing): Disconnect all wires from the old controller, noting their positions and connections. Take photos if necessary.
4. Install New Controller: Connect the new controller to the motor and all peripheral components (display, throttle, brake sensors, speed sensor, light, etc.) according to the wiring diagram provided with your specific motor model.
5. Secure Controller: Mount the controller securely within the motor housing.
6. Reconnect Power: Once all connections are secure and verified, reconnect the battery.
7. Initial Test: Power on the e-bike and perform a functional test to ensure all components are working correctly.

4. Operating the E-bike System

Once the controller is correctly installed, the e-bike system can be operated via the display unit and throttle/pedal assist system (PAS).

• Power On/Off: Use the power button on your e-bike display to turn the system on or off.
• Pedal Assist Levels: Adjust the pedal assist level (PAS) via the display unit. Higher levels provide more motor assistance.
• Throttle (if equipped): The throttle provides instant motor power without pedaling. Use it cautiously, especially at higher assist levels.
• Display Information: The display shows important information such as speed, battery level, assist level, and trip distance.
• Brake Cut-off Sensors: Ensure your brake levers are equipped with cut-off sensors that immediately stop motor power when brakes are applied.

5. Maintenance

Regular maintenance helps ensure the longevity and reliable performance of your BAFANG mid-drive motor controller and e-bike system.

• Keep Clean: Periodically clean the exterior of the motor and controller area to prevent dirt and debris buildup.
• Check Connections: Regularly inspect all electrical connections for corrosion, looseness, or damage. Ensure they are secure.
• Avoid Overheating: Do not operate the motor at maximum power for extended periods, especially in hot weather or steep climbs, to prevent overheating.
• Protect from Water: While BAFANG components are generally water-resistant, avoid submerging the motor or controller in water.
• Software Updates: If available, keep your controller's firmware updated. Consult BAFANG's official resources or a certified dealer for updates.
