Torque-Sensor Pedal Assistance

The integrated torque sensor measures the rider's pedalling input and helps regulate motor assistance for a more natural riding experience.

The system is designed to provide assistance in different riding situations, including commuting, recreational cycling and climbing, depending on the selected motor configuration.

Motor Options

Choose the motor configuration that best suits your requirements:

• TSDZ2B 250W: A lower-power option for compatible everyday and commuter e-bike builds.
• TSDZ8 750W: A higher-powered option for builds requiring increased assistance.
• TSDZ16 1000W: A high-power option for compatible performance-focused conversions.

Voltage, torque, controller specifications, display compatibility and battery requirements vary by motor model. Confirm the exact specifications of your selected configuration before ordering.

Four Riding Modes

The supplier lists four operating modes, depending on the selected motor and display:

• Pure Electric Mode: Motor-driven operation where supported by the selected configuration.
• Manual Riding Mode: Ride using pedal power without electric assistance.
• Pedal-Assistance Mode: The motor assists while you pedal.
• Walk/Push Mode: Provides assistance when walking the bicycle, where supported.

Throttle availability depends on the selected configuration and applicable local regulations.

Bicycle Compatibility

The kit is designed for compatible bicycles with 68-73mm bottom brackets.

Before ordering, check:

• Bottom bracket width and standard
• Frame clearance around the motor housing
• Battery mounting space
• Drivetrain and chainline compatibility
• Brake system and electrical connections

The supplier advises that the kit is generally not suitable for fat bikes. It does not support coaster-brake operation.

Battery & Electrical Connections

The supplier specifies XT60 battery connectors as standard.

Battery voltage and capacity must match the selected motor, controller and display. Battery inclusion depends on the chosen kit configuration, despite the supplier's general listing title referring to a battery.

Confirm the exact battery specifications and package contents before purchasing.

Important Notes

Select the correct motor, voltage and battery combination before ordering. The TSDZ2B, TSDZ8 and TSDZ16 are different motor models and may have different electrical and mechanical requirements.

The supplier's general specifications do not establish one universal voltage, torque rating or battery specification for all three models. Confirm these details for the exact configuration selected.

Compatibility depends on frame clearance, bottom bracket dimensions, drivetrain, battery mounting and electrical connections. Professional installation is recommended.

Higher-powered configurations may exceed the legal power and speed limits for road-legal e-bikes in your jurisdiction. Check local regulations before installation and use. A supplied 250W label does not change the motor's actual rated power.

One-year warranty for main components.
