BAFANG DPC18 Ebike Display User Manual
Model: DPC18
Introduction
This manual provides essential information for the installation, operation, and maintenance of your BAFANG DPC18 3.5" LCD EBike Display. This display is specifically designed for use with BAFANG BBS01B, BBS02B, and HD mid-motor systems, as well as compatible BAFANG hub motors that utilize the UART protocol with a 5-pin circular connector.
Important Compatibility Note: This display operates using the UART protocol and is not compatible with CAN protocol motors, which typically feature a 5-pin pentagonal connector. Attempting to connect this display to a CAN protocol motor using adapter cables or by modifying connectors will not resolve compatibility issues. Please verify your motor's connector type before installation.

Setup and Installation
1. Unpacking
Carefully remove the BAFANG DPC18 display and its components from the packaging. Verify that all parts are present and undamaged.
2. Mounting the Display
- Choose a suitable position on your ebike's handlebar for the display, ensuring it is easily visible and accessible without obstructing your view or controls.
- The display holder supports handlebar diameters of φ22.2mm, φ25.4mm, and φ31.8mm. Use the appropriate shims if necessary to secure the display firmly.
- Tighten the mounting screws to secure the display in place. Do not overtighten.
3. Connecting the Cables
The DPC18 display connects to your ebike's mid-drive or hub motor system via a 5-pin female circular connector (UART protocol). Ensure your motor system has a compatible male 5-pin circular connector.

- Locate the main cable from your ebike's motor system.
- Align the 5-pin female circular connector of the DPC18 display with the corresponding male connector from your ebike's wiring harness.
- Gently push the connectors together until they click securely into place. Ensure the connection is firm to prevent accidental disconnection during riding.
- Route the cables neatly along the handlebar and frame, securing them with cable ties to prevent snagging or damage.

The integrated light sensor automatically turns on the ebike's headlight and adjusts the display's backlight when ambient light conditions dim. You can also manually adjust the backlight intensity through the display settings (1-5 levels).
5. USB Charging Port
The display features a USB charging port (5V, 500mA) located on the side. This port can be used to charge small electronic devices such as smartphones or GPS units while riding.
Maintenance
- Cleaning: Wipe the display screen and casing with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the screen or plastic components.
- Water Resistance: The display has an IPX5 water-resistant rating, meaning it is protected against low-pressure water jets from any direction. Avoid submerging the display in water or exposing it to high-pressure washing.
- Cable Inspection: Periodically check all cable connections for tightness and signs of wear or damage. Ensure cables are securely routed and not pinched.
- Storage: When not in use for extended periods, store the ebike and display in a dry, temperate environment.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display does not power on. | Low or dead ebike battery. Loose cable connection. Faulty display or motor. | Charge the ebike battery. Check all cable connections, especially the main display cable. Ensure it is fully seated. Contact BAFANG support if the issue persists after checking connections and battery. |
| Display shows error code. | Motor or sensor malfunction. | Note the specific error code displayed. Refer to your ebike motor's manual for error code definitions. Common issues include motor overheating, hall sensor errors, or controller issues. Contact BAFANG support with the error code for assistance. |
| Inaccurate speed or mileage readings. | Incorrect wheel circumference setting. Loose speed sensor magnet. | Access display settings to verify and adjust the wheel circumference. Check the speed sensor and magnet on your wheel to ensure they are properly aligned and secured. |
| PAS levels not changing or motor not assisting. | Loose motor connection. PAS sensor issue. Brake lever cut-off switch engaged. | Check all motor and PAS sensor connections. Ensure brake levers are not stuck in the engaged position, as many ebike systems cut motor power when brakes are applied. |
