Setup and Installation
Follow these steps carefully to install your electric bike controller kit.
1. Controller Mounting
- Identify a suitable location on your bicycle frame for the controller. Ensure it is protected from direct impact and excessive moisture.
- Use the provided screws and nuts to securely mount the controller. The aluminum alloy housing is designed for heat dissipation, so ensure adequate airflow around it.
Figure 2: Controller dimensions: approximately 150mm (5.9in) length, 60mm (2.4in) width, and 35mm (1.4in) height. These dimensions help in selecting a suitable mounting location.
2. LCD Panel Installation
- Attach the UKC1 LCD panel to your handlebar using the provided clamps and washers. Position it for optimal visibility and easy access to the control buttons.
- Ensure the panel is securely fastened and does not obstruct steering or braking.

3. Wiring Connections
The controller features various color-coded wires for different functions. Connect them according to your motor and battery system. Refer to the diagram below for general guidance. If you are unsure, consult a professional.
- Motor Wires: Connect the thick phase wires (usually green, blue, yellow) from the controller to the corresponding motor phase wires. Connect the thinner Hall sensor wires.
- Battery Wires: Connect the thick red wire from the controller to the positive (+) terminal of your battery and the thick black wire to the negative (-) terminal.
- LCD Panel Wire: Connect the multi-pin connector from the LCD panel to the corresponding port on the controller.
- Brake Levers: Connect the brake lever wires to the controller. These typically provide a low-level input to cut motor power when brakes are applied.
- Throttle: Connect the throttle wire to the controller.
- Pedal Assist Sensor (PAS): Connect the PAS sensor wire if your system includes one.

- To power off, press and hold the power button again until the display turns off.
2. LCD Display Functions
The UKC1 LCD panel provides real-time information about your electric bicycle's status:
- Battery Level: Indicates the remaining battery charge.
- Speed: Displays current riding speed.
- Assist Level/Mode: Shows the current pedal assist level (e.g., 1-3 or 1-5, depending on configuration).
- Trip Distance: Records the distance traveled for the current ride.
- Odometer: Displays total distance traveled.
- Error Codes: May display codes if a system error occurs. Refer to the Troubleshooting section.

3. Adjusting Assist Levels
Use the '+' and '-' buttons on the LCD panel to cycle through the available pedal assist levels. Higher levels provide more motor assistance.
4. Throttle Operation (if applicable)
If a throttle is installed, gently twist or press it to engage motor power independently of pedaling. Always use the throttle responsibly and be aware of your surroundings.
Maintenance
- Cleaning: Wipe the controller and LCD panel with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure no water enters the electrical components.
