Key Connections:

• Hub Motor: Install the front hub motor wheel into your bicycle's front fork.
• Controller: Mount the controller securely, typically in a controller box.
• Battery: Connect your 48V battery to the controller. Ensure the battery is fully charged before first use.
• PAS Sensor: Install the Pedal Assist Sensor (PAS) on your bike's bottom bracket. Ensure correct left or right side installation as per the diagram.
• Throttle: Attach the thumb throttle to your handlebar.
• Display: If using an optional display, connect it to the 1T4 cable.
• Brake Levers: Connect the brake levers (or brake sensors if preferred) to the system. The kit defaults to brake levers; contact the seller if brake sensors are desired.
• 1T4 Cable: This central cable connects multiple components (throttle, display, brake levers) to the controller.

Ensure all connections are secure and waterproof. The system features durable waterproof connectors for enhanced reliability.

3. Operating Instructions

Once installed, your BAFANG Ebike Conversion Kit offers multiple riding modes to suit your preferences and riding conditions.

3.1 Riding Modes

The kit supports four distinct riding modes:

• Pure Electric Mode (Throttle): Engage the thumb throttle for full electric power without pedaling. Ideal for quick acceleration or when you need a break from pedaling.
• Pedal Assisted Mode (PAS): The motor provides assistance as you pedal. The level of assistance can typically be adjusted via the display, offering a natural riding feel while reducing effort.
• Walking Assisted Mode: Provides low-speed motor assistance (e.g., 6 km/h) to help you push the bike when walking alongside it, useful for navigating crowded areas or steep ramps.
• Physical Riding Mode: The motor is disengaged, and the bike operates as a traditional bicycle, relying solely on pedal power.

3.2 Digital Display (Optional)

If you have opted for a digital display, it provides essential information and control over your ebike system. Displays can track speed, battery life, mileage, and allow adjustment of pedal assist levels. Some advanced displays offer Bluetooth connectivity for GPS navigation and smartphone integration.

Refer to your specific display's manual for detailed operation instructions, including power on/off, mode switching, and settings adjustments.

4. Maintenance

Proper maintenance ensures the longevity and optimal performance of your BAFANG Ebike Conversion Kit. Regular checks and care are essential.

4.1 General Care

• Cleaning: Clean the motor, controller, and other components with a damp cloth. Avoid high-pressure washing directly on electrical parts.
• Connections: Periodically check all electrical connections for tightness and ensure they are free from dirt or corrosion. The kit features IPX5 waterproofing, but proper care extends component life.
• Cables: Inspect cables for any signs of wear, fraying, or damage. Replace damaged cables immediately.
• Fasteners: Ensure all bolts and fasteners on the motor, controller, and other mounted components are secure.

4.2 Battery Care (Optional Component)

While the battery is an optional component purchased separately, proper care is crucial for its lifespan and safety:

• Charging: Use only the charger provided or recommended by the battery manufacturer. Do not overcharge.
• Storage: Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, maintain a charge level between 40-60%.
• Water Exposure: Although many batteries are weather-resistant, avoid submerging them in water. If the battery gets wet, ensure it is completely dry before charging or using.
• Security: Utilize the built-in lock mechanism (if available) to secure the battery to your bike.
