Why choose the little motor- TSDZ2B 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.
• 80Nm of torque
• The TSDZ2B 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 & crank set assembly - to utilize the existing drivetrain & gears for maximum efficiency.
• The VLCD-5 Display - w/ Throttle & E-brakes: The VLCD-5 is a larger, center 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).

What improvements have been made when comparing the new TSDZ2B to the old version?

• The upgraded TSDZ2B now features an all-in-one reduction gear kit, which cannot be separated, making it more robust and stable.
• Additionally, the one-way needle bearing has been replaced with an all-in-one nylon gear in the new TSDZ2B version, providing increased torque with an external clutch.
• Moreover, the new bi-directional freewheeling clutch enables you to ride your bike as a regular bicycle when the power is depleted.
