TongSheng 48V 500W TSDZ2 with Torque Sensor Mid Drive Motor Electric Bike Conversion Kit

Sold out
SKU TSDZ236V250W-1

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 VLCD-5 Display - w/ Throttle & E-brakes: The VLCD-5 is a larger, centre mounted display with ports and wiring for a throttle, e-brakes, and an external handlebar mounted button panel. It also houses a USB port for charging your mobile device (installation/use of the throttle, e-brakes, and/or external button panel is optional).
