Why choose the little motor- TSDZ2 Mid drive motor?

  • Fits 95% of standard bike frames with 68-73mm bottom bracket built in torque and cadence sensor- this results in much smoother acceleration than any cadence sensor mid drive motor.

  • Easy to install. Kit includes all installation parts and tools.

  • The motor has an extra support mount - resulting in a much more reliable install.

  • 90Nm of torque 

The TSDZ2 Mid Drive Motor - Torque Sensing Pedal Assist: The harder you pedal - the harder the motor works with you. 4 levels of assist provide smoothly integrated power ranging from +36-300%, allowing you to conquer virtually any hill with ease. These kits retrofit most bicycles by replacing the bottom bracket & crankset assembly - to utilise the existing drivetrain & gears for maximum efficiency

The XH-18 Display - The compact left handlebar mount XH-18 features a spring loaded half twist to function as the +\- buttons to adjust the level of assist, as well as cycle menu options. This is a very smooth way to adjust your assist level on the fly. The power button doubles as on/off for the lights with a short press, and the information button toggles the trip/odometer readout. You can also adjust the settings for wheel diameter, change the speed limit, switch between miles or kph, and more.   

48V 500W Version

  • Assisted Speeds up to 45 kmh  (motor does not provide assist past programmed limit on model, 45kmh being the maximum value - while you can set the motor speed limit higher on the 36v models, we recommend the more powerful 48v for speeds up to 45 kmh) Please note: 25 km/h is the legal limit within Australia for on-road use
