5. Operating Instructions

Once installed, the controller manages the electric bicycle's motor functions based on user input (throttle, pedal assist) and system parameters.

• Power On/Off: Use the bicycle's main power switch or display unit to turn the system on or off. The controller will activate upon power-up.
• Throttle Control: The controller interprets throttle input to regulate motor speed and power output. Apply throttle smoothly for consistent acceleration.
• Brake Cut-off: When the brake levers are engaged, the controller is designed to cut power to the motor, ensuring safe stopping.
• Display Integration: If connected to a display, the controller communicates essential information such as speed, battery level, and assist mode.

6. Maintenance

Proper maintenance ensures the longevity and reliable performance of your controller:

• Keep Clean: Periodically clean the exterior of the controller with a dry cloth. Avoid using water or harsh chemicals.
• Check Connections: Regularly inspect all wire connections for looseness, corrosion, or damage. Secure any loose connections.
• Environmental Protection: Protect the controller from direct exposure to heavy rain, extreme heat, or prolonged direct sunlight.
• Avoid Impact: Prevent physical impact to the controller, as internal components can be sensitive.
