4. Setup and Installation
This section outlines the general steps for installing the motor kit. Detailed wiring diagrams are provided to assist with electrical connections.
Motor Mounting
- Identify a suitable mounting location on your vehicle frame that can securely support the motor's weight and dimensions.
- Ensure adequate clearance for the motor, sprocket, and chain.
- Use appropriate bolts and nuts (provided in the assembly hardware kit) to firmly attach the motor to the frame. Ensure all fasteners are tightened to prevent vibration and movement during operation.
Electrical Connections
The motor controller is the central hub for all electrical connections. Refer to the wiring diagram below for correct connections. Incorrect wiring can damage the components or lead to unsafe operation.

- Motor Phase Wires: Connect the three thick motor phase wires (typically yellow, green, blue) from the motor to the corresponding motor phase terminals on the controller.
- Battery Connection: Connect the main battery positive and negative terminals to the controller's battery input. Ensure correct polarity. The controller features an XT60 connector for enhanced power connection stability.
- Throttle Grip: Connect the twistgrip throttle to the designated throttle port on the controller.
- Brake Levers: Connect the brake signal wires from your brake levers to the controller's brake input. This enables motor cut-off when braking.
- Hall Sensor: Connect the Hall sensor wires from the motor to the controller's Hall sensor port.
- Other Connections: Connect any additional accessories such as E-lock, 3-speed switch, reverse switch, or indicator lights according to the provided diagram.
After all connections are made, double-check them for security and correctness before applying power.
5. Operating Instructions
Once the motor kit is correctly installed and wired, follow these steps for operation:

- Power On: Turn on the main power switch (if applicable) to supply power to the controller.
- Soft Start: The motor adopts intelligent soft-start technology, ensuring a smooth and safe startup process. Avoid sudden full throttle application.
- Speed Control: Gently twist the throttle grip to accelerate. The controller supports 3-level speed adjustment, allowing adaptation to various terrains and riding preferences.
- Braking: Apply the brake levers to slow down or stop. The electronic brake feature provides sensitive response and cuts off motor power for safety.
- Reverse Function: If connected, use the reverse switch to engage reverse mode. This is useful for maneuvering in tight spaces. The controller ensures smooth reverse operation.
- Power Off: When finished, turn off the main power switch.
Motor Rotation
The motor supports both Clockwise (CW) and Counter-Clockwise (CCW) rotation, allowing for versatile application depending on your vehicle's drive system requirements.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your VEVOR motor kit.
- Cleaning: Keep the motor and controller free from dirt, dust, and moisture. Use a dry cloth to wipe down surfaces. Avoid using water or harsh chemicals.
- Connections: Periodically check all electrical connections for tightness and corrosion. Re-tighten any loose connections.
- Wiring: Inspect wiring for any signs of wear, fraying, or damage. Replace damaged wires immediately.
- Sprocket and Chain: Ensure the sprocket and chain are clean and properly lubricated. Check for excessive wear and replace if necessary. Maintain proper chain tension.
- Motor Housing: Inspect the motor housing for any physical damage or signs of overheating. The 100% copper core motor is designed for excellent heat and cold resistance, but proper ventilation is still important.
