2. Install the Hub Motor Wheel
- Carefully place the new hub motor wheel into the rear dropouts of your bicycle frame. Ensure the motor cable exits without obstruction.
- Secure the wheel using the axle nuts. Tighten them firmly to prevent movement.
3. Install Brake Levers and Throttle
- Remove your original brake levers and grips from the handlebars.
- Install the new brake levers (which include motor cut-off switches) and the twist throttle onto the handlebars.
- Connect the brake cables to your bicycle's brake calipers/mechanisms and adjust for proper braking function.
4. Install Pedal Assist Sensor (PAS)
- Install the pedal assist sensor (PAS) onto the crank arm or bottom bracket area, ensuring it is correctly aligned with the magnetic disc.
- Secure the PAS sensor and route its cable towards the controller.
5. Connect the Controller and Wiring
- Mount the intelligent motor controller in a suitable location on your bike frame, preferably within the provided controller bag.
- Connect all cables to the controller: motor cable, brake lever cables, throttle cable, and PAS sensor cable. Ensure all connections are secure and match the color coding.
- Use the provided cable ties and plastic coil to neatly manage and protect the wiring.

2. Pedal Assist System (PAS)
- The PAS system provides motor assistance as you pedal. The level of assistance can often be adjusted via the display unit (if equipped).
- This system allows for a natural cycling experience with added power, extending your range and reducing effort.
3. Twist Throttle
- The twist throttle provides on-demand power, allowing you to accelerate without pedaling.
- Twist the throttle gently to engage the motor. The battery level display on the throttle indicates remaining power.
4. Brake Levers
- The included brake levers are equipped with motor cut-off switches. Engaging the brakes will immediately cut power to the motor, ensuring safe stopping.
Maintenance
- Regular Inspection: Periodically check all electrical connections for tightness and signs of wear. Inspect brake pads and cables for proper function.
- Tire Pressure: Maintain correct tire pressure as indicated on the tire sidewall.
- Cleaning: Clean the motor and controller with a damp cloth. Avoid high-pressure washing directly on electrical components.
- Battery Care: Follow the manufacturer's instructions for your specific battery model regarding charging, storage, and maintenance.
