High-Torque Mid-Drive Performance

The 750W BBS02B motor provides high torque through a central drivetrain position, helping deliver strong acceleration and climbing performance.

With a maximum torque rating of up to 160Nm, the motor is designed for demanding e-bike applications where additional assistance is required.

The geared motor uses a 1:21.9 reduction ratio and operates at approximately 130-150 RPM.

CAN Bus Communication

The CAN Bus version provides communication between compatible components, allowing the motor, display and compatible BAFANG battery systems to exchange information.

The battery communication cable can be left unused when a compatible BAFANG communication battery is not being used.

The motor uses an XT60 male power connector, so the battery should have a compatible XT60 female connector.

Chainring Options

The conversion system supports multiple chainring configurations:

• 44T
• 46T
• 48T
• 52T

The appropriate chainring can be selected according to the intended bicycle setup and drivetrain requirements.

Display Options

Compatible display options include:

• B02N-C
• DZ41
• 860C
• DP C010
• SW102
• Without LCD display

Display availability depends on the selected configuration.

Brake & Gear Sensor Compatibility

The system can operate with or without brake sensors connected.

Brake sensor options are available for different bicycle braking systems. Standard brake levers can be used with compatible cable-operated brakes, while magnetic brake sensors can be used to adapt existing hydraulic brake systems.

The system also supports a gear sensor function where compatible components are fitted.

48V Battery Compatibility

This listing is for the 48V motor version.

The 48V motor is designed for use with 48V batteries with a maximum output voltage of approximately 54.6V.

A 52V battery should not be used with the 48V motor. The supplied specifications state that using a 52V battery with the 48V version can result in an Error 07 over-voltage condition and prevent the motor from operating.

Always confirm your battery voltage before ordering.

Package & Configuration

The exact contents depend on the selected kit configuration and may include:

• BAFANG BBS02B 48V 750W mid-drive motor
• Chainring
• Crank components
• Power cable
• Battery communication cable
• Speed sensor
• Display, if selected
• Brake sensor or brake lever option, if selected
• Gear sensor components, where applicable
• Installation accessories

Battery availability depends on the selected configuration.

Important Notes

This is a 750W high-power conversion system and may exceed the legal power or speed limits for road-legal e-bikes in some countries and jurisdictions. Check applicable local regulations before installation and use.

The motor requires a compatible 48V battery. A 52V battery should not be connected to this 48V version.

The battery is not automatically included unless specifically selected as part of the configuration.

Compatibility depends on the bicycle frame, bottom bracket dimensions, drivetrain, battery, brakes and available mounting space. Confirm your bicycle specifications before ordering.

Professional installation is recommended, particularly when connecting the battery, brake sensors, gear sensor and lighting system.

Actual performance, speed, range and torque will vary depending on battery capacity, controller configuration, gearing, wheel size, rider weight, terrain and riding conditions.
