Installation Guide
Proper installation is crucial for the display's functionality and your safety. Follow these steps carefully.
1. Handlebar Mounting:
The display comes with a holder compatible with handlebar sizes: 22.2mm, 25.4mm, 28.6mm, and 31.8mm. Select the appropriate mounting position on your handlebar that allows for clear visibility and easy access to controls without obstructing your view or steering.

2. Electrical Connection:
The H6C display uses a 5-pin male waterproof cable. Connect this cable to your ebike controller's corresponding 5-pin female connector. Ensure the communication protocol of your controller is UART No. 2, as this display is only compatible with controllers using the same protocol.

- Speed Limit Adjustment: Modify the maximum assisted speed (subject to local regulations).
- Walk-assist Mode: Provides low-speed assistance for walking the bike.
- Cruise Control: Maintain a constant speed without continuous throttle input.
The integrated USB charging port (5V/500mA) can be used to charge mobile devices while riding.
Maintenance
To ensure the longevity and optimal performance of your H6C Ebike LCD Display Meter, follow these maintenance guidelines:
- Cleaning: Wipe the display screen and housing with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the screen or plastic components.
- Protection: While the display is designed to be rugged and waterproof, avoid prolonged exposure to extreme weather conditions or direct high-pressure water jets.
- Connection Check: Periodically inspect the 5-pin connector for any signs of wear, corrosion, or loose connections. Ensure it remains securely fastened.
- Storage: If storing your ebike for an extended period, ensure the display is clean and dry. Store in a cool, dry place away from direct sunlight.
Troubleshooting
If you encounter issues with your H6C Ebike LCD Display Meter, refer to the following common problems and solutions:
- Display Not Powering On:
- Check the main power supply to your ebike.
- Ensure the 5-pin connector is securely and correctly plugged into the controller.
- Verify that your ebike controller is powered on.
- Incorrect Readings (Speed/Mileage):
- Ensure the wheel diameter setting in the display's menu is correctly configured for your ebike's wheel size.
- Check the speed sensor connection on your ebike.
- Display Shows "Fault Prompt" or Error Code:
- Consult your ebike controller's manual for specific error code interpretations.
- Common issues include motor, battery, or sensor malfunctions.
- Display Not Communicating with Controller:
- Crucial: Confirm that your ebike controller uses the UART No. 2 communication protocol. This display is only compatible with controllers using this specific protocol. If your controller uses a different protocol, the display will not function.
- Check for any damage to the 5-pin communication cable.
- USB Charging Not Working:
- Ensure the ebike system is powered on.
