Follow these steps carefully to install your BAFANG 48V 500W Rear Hub Motor Kit. It is recommended to have basic bicycle maintenance knowledge or seek professional assistance if unsure.
Figure 6.1: General wiring diagram for the BAFANG Ebike Conversion Kit.
- Prepare Your Bicycle:
- Remove your existing rear wheel.
- Ensure the rear dropout width is compatible (135-142mm).
- Install the Hub Motor Wheel:
- Carefully install the BAFANG rear hub motor wheel into your bike's rear dropout.
- Secure it firmly with the provided nuts and washers.
- Mount the Controller Box:
- Find a suitable location on your bike frame for the controller box, typically near the seat tube or down tube.
- Secure the controller box using the provided plastic straps or mounting hardware.
- Install Brake Levers/Sensors:
- Replace your existing brake levers with the provided e-bike brake levers, or install the brake sensors onto your existing levers.
- Ensure the brake cut-off function is correctly installed and tested.
- Install Thumb Throttle:
- Mount the thumb throttle on your handlebar in a comfortable and accessible position.
- Install PAS Sensor:
- Install the Left Pedal Assist Sensor (PAS) on your bike's bottom bracket, ensuring the magnets and sensor are correctly aligned and spaced.
- Connect 1T4 Cable:
- Connect the 1T4 cable to the controller. This cable typically branches out to connect the display, throttle, and brake levers/sensors.
- Connect Display:
- Mount your chosen display (e.g., 500C) on the handlebar.
- Connect the display cable to the 1T4 cable or directly to the controller if applicable.
- Connect Headlight:
- Connect the headlight to the designated port on the controller or 1T4 cable.
- Connect Battery:
- Securely mount your 48V or 52V battery (purchased separately) to your bike frame.
- Connect the battery to the controller using the XT60 connector.
- Cable Management:
- Route all cables neatly and secure them with zip ties or plastic straps to prevent snagging or damage.
- Ensure no cables interfere with moving parts like wheels or pedals.
- Initial Test:
- Before riding, lift the rear wheel off the ground and power on the system.
- Test the throttle, pedal assist, and brake cut-off functions to ensure they are working correctly.

7. Operating Instructions
Your BAFANG Ebike Conversion Kit offers four primary riding modes, allowing you to customize your riding experience. The 500C display provides essential information and control over these modes.
Figure 7.1: Overview of the 500C Smart Digital LCD Display.
7.1 Riding Modes
- Throttle Mode: Engage the thumb throttle to propel the bike without pedaling. The motor provides power directly based on throttle input.
- Pedal Assist Mode (PAS): The motor provides assistance as you pedal. The level of assistance can be adjusted via the display (typically 3, 5, or 9 levels). This mode extends battery life and reduces rider effort.
- Walk Assist Mode: Provides low-speed motor assistance to help you push the bike when walking alongside it. This is useful for navigating crowded areas or steep inclines off the bike.
- Pedal-Only Mode: The motor provides no assistance, and the bike functions as a traditional bicycle.
7.2 Display Operation (500C Example)
The 500C display allows you to monitor your ride data and control kit settings:
- Power On/Off: Press and hold the power button to turn the system on or off.
- PAS Level Adjustment: Use the '+' and '-' buttons to cycle through pedal assist levels.
- Information Display: The screen shows current speed, battery level, power output, trip distance, and total mileage.
- Settings: Access advanced settings (e.g., wheel size, speed limit, password) through the display menu. Refer to your specific display's manual for detailed instructions on advanced settings.
8. Maintenance
Regular maintenance ensures the longevity and safe operation of your BAFANG Ebike Conversion Kit.
- Cleaning: Clean the motor, controller, and display with a damp cloth. Avoid high-pressure washing directly on electrical components.
- Connections: Periodically check all electrical connections for tightness and corrosion. Ensure waterproof connectors are properly sealed.
- Cables: Inspect cables for any signs of wear, fraying, or damage. Replace damaged cables immediately.
- Motor: The brushless geared motor is largely maintenance-free. Keep the motor housing clean.
- Battery: Follow the battery manufacturer's instructions for charging, storage, and maintenance. Do not expose the battery to extreme temperatures.
- Brakes: Ensure your brakes are functioning correctly, especially the e-bike specific brake cut-off sensors.
- General Bike Maintenance: Continue to perform regular maintenance on your bicycle's mechanical components (tires, chain, gears, etc.) as you would with a standard bike.
