2. Safety Information
Before installation and use, please read and understand all safety warnings. Improper installation or handling can lead to damage to the product, e-bike components, or personal injury.
- Always disconnect the e-bike battery before performing any electrical work or installation.
- Ensure all connections are secure and properly seated to prevent short circuits or intermittent operation.
- Avoid pinching or sharply bending the cable during installation to prevent internal wire damage.
- Keep cables away from moving parts and heat sources.
- Warning: Please mind potential fire risk and strictly follow the instruction manual for charging and storage of your e-bike battery. Ensure cable integrity to prevent electrical hazards.
3. Setup and Installation
The EB-BUS 1T1 cable is designed for straightforward integration into your BAFANG central motor system. Follow these steps for proper installation:
- Prepare the E-bike: Ensure the e-bike is powered off and the battery is removed or disconnected.
- Identify Connections: The EB-BUS 1T1 cable features distinct connectors for the motor, display, and front light. Refer to Figure 2 for identification.
- Connect to Motor: Locate the main EB-BUS port on your BAFANG M500, M510, or M600 central motor. Connect the corresponding end of the 1T1 cable (labeled 'Motor' or the main input) securely.
- Connect to Display: Attach your e-bike's display unit cable to the connector labeled 'display' on the 1T1 main line cable. Ensure a firm connection.
- Connect Front Light: If using a 6V front light, connect its power cable to the designated '6V-12V lamp' connector on the 1T1 cable. Note that this output is specifically for 6V lights.
- Cable Routing: Carefully route the cable along your e-bike frame, securing it with cable ties or clips to prevent snagging, rubbing, or damage. Ensure there is enough slack for handlebar movement if the display is mounted there.
- Reconnect Battery: Once all connections are made and secured, reconnect your e-bike battery.
- Test Functionality: Power on your e-bike and verify that the display unit functions correctly and the front light (if connected) illuminates.

4. Operating Instructions
The EB-BUS 1T1 cable is a passive component that enables the functionality of your e-bike's display and front light. Once correctly installed, its operation is integrated with your e-bike's electrical system:
- Display Functionality: The cable transmits data and power between the central motor and the display unit, allowing you to monitor speed, battery level, assist level, and other relevant information.
- Front Light Control: If a 6V front light is connected, it will typically be controlled via your e-bike's display unit or a dedicated light button, depending on your e-bike's specific configuration.
5. Maintenance
Proper maintenance of your EB-BUS 1T1 cable ensures longevity and reliable performance:
- Regular Inspection: Periodically check the cable for any signs of wear, cuts, abrasions, or damage to the connectors.
- Cleaning: Keep the cable and connectors clean and free from dirt, mud, and moisture. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals.
- Secure Routing: Ensure the cable remains securely routed and fastened to the frame to prevent it from getting caught or damaged during riding.
- Connector Care: Avoid pulling on the cable itself when disconnecting; always grasp the connector housing.
6. Troubleshooting
If you experience issues with your display or front light, consider the following troubleshooting steps:
- Display Not Powering On:
- Check if the e-bike battery is charged and properly connected.
- Verify that the EB-BUS 1T1 cable's motor and display connectors are fully seated and secure.
- Inspect the cable for any visible damage (cuts, pinches).
- Front Light Not Working:
- Ensure the front light is a 6V model and is correctly connected to the '6V-12V lamp' port.
- Check if the light is switched on via the display or dedicated button.
- Verify the light's own wiring and functionality.
- Intermittent Functionality:
- This often indicates a loose connection. Re-seat all connectors firmly.
- Inspect the cable for internal damage that might not be visible externally.
If issues persist after these steps, consult a qualified e-bike technician or contact the seller for further assistance.
