2. Compatibility Check

Before proceeding with installation, it is crucial to confirm that the BAFANG mid-drive motor kit is compatible with your bicycle frame. The motor is designed to fit bikes with a standard 68-73mm bottom bracket length and an inner diameter between 34-36mm.

2.1. Bottom Bracket Measurement

Measure the width of your bicycle's bottom bracket shell. The motor is compatible with widths between 68mm and 73mm. Also, measure the inner diameter of the bottom bracket, which should be between 34mm and 36mm.

Image: Bottom Bracket Compatibility. This diagram illustrates how to measure the bottom bracket shell width (68-73mm) and inner diameter (33.5mm-24TPI, between 34-36mm) to ensure compatibility with the BAFANG mid-drive motor. It also shows incompatible coaster brake and carbon fiber bikes.

2.2. Incompatible Bicycle Types

• Coaster Brake Bikes: The BAFANG mid-drive motor is not compatible with bicycles equipped with coaster brakes.
• Carbon Fiber Bikes: Due to potential stress on the frame, carbon fiber bicycles are generally not recommended for mid-drive motor conversions.

2.3. Battery Compatibility

If you are purchasing a battery separately, ensure it fits your bike frame. For downtube shark batteries, use a size guide template to check clearance. For rear rack batteries, verify installation screw holes on your rear fork and check the size of your rear fork (typically A: 150-160MM).

4. Setup and Installation

The BAFANG mid-drive kit is designed for straightforward installation. Follow these general steps. For detailed, step-by-step instructions, refer to the specific installation guide provided with your kit or available online.

4.1. Motor Installation

1. Remove the existing bottom bracket and crankset from your bicycle.
2. Insert the BAFANG mid-drive motor into the bottom bracket shell.
3. Secure the motor using the provided lock nuts and mounting plates.
4. Install the chainwheel and cranks onto the motor spindle.

4.2. Component Wiring

Connect all peripheral components to the main 1T4 cable harness. The system uses waterproof connectors for durability.

• Connect the display to its designated port.
• Attach the throttle to its connector.
• Install and connect the brake levers or brake sensors. If your bike cannot use the default brake levers, contact support for brake sensors.
• Mount and connect the speed sensor to the rear wheel.
• Connect the battery to the motor's power cable. Ensure the battery is securely mounted.
• Optional accessories like headlights, taillights, and gear shift sensors should also be connected to their respective ports on the 1T4 cable.

4.3. Brake Lever or Brake Sensor

The kit typically comes with brake levers that integrate a motor cut-off switch. If your bicycle's existing brake system (e.g., hydraulic disc brakes or integrated shift/brake handles) is not compatible with the provided levers, you may need brake sensors. These sensors attach to your existing brake cables and provide the motor cut-off function.

Image: Brake Compatibility. This image shows examples of mechanical disc brakes and rim V-brakes as compatible, while shift-integrated brake handles and hydraulic disc brakes are typically incompatible with the standard brake levers, requiring brake sensors.

5. Operating Instructions

Once installed, your BAFANG ebike kit offers various modes of operation to enhance your riding experience.

5.1. Display Operation (750C Display)

The 750C display provides essential riding information and allows you to control the motor's assistance levels. It features a 3.2-inch IPS screen, a USB port for charging devices, and Bluetooth functionality.

• Power On/Off: Press and hold the power button to turn the system on or off.
• PAS Level Adjustment: Use the up/down buttons to select your desired Pedal Assist System (PAS) level (typically 0-9). Level 0 provides no assistance, while higher levels offer more motor power.
• Information Display: The screen shows speed, battery level, trip distance, and other metrics.
• USB Port: Use the integrated USB port to charge your mobile phone or other small electronic devices while riding.
• Bluetooth Function: The 750C display includes Bluetooth for connectivity with compatible apps or devices.

5.2. Riding Modes

The BAFANG mid-drive system supports multiple riding modes:

• Throttle Mode (Rapid Climb): Engages the motor directly via the thumb throttle, providing power without pedaling. Ideal for quick acceleration or climbing steep inclines.
• Pedal Assist System (PAS Mode - Save Effort): The motor provides assistance proportional to your pedaling effort. You can adjust the level of assistance via the display.
• Normal Bike Mode (Exercise Mode): The motor is off, and the bicycle functions as a standard pedal bike.
