The TongSheng mid drive motor is our new addition to the range. This new motor allows for an easy way to convert your bike to an ebike. This motor can do up to 45kmph! This 500W or 750W motor is packed with features. Compared to Bafang motors this is also a Torque sensing motor. A torque sensor measures how hard the rider is pedaling to determine how much electric power to push to the bike. The TongSheng Mid Motor gives you more power when you need it most. This innovative motor responds in real time to your pedaling.

The TongSheng TSDZ2B  is the newest model that comes with a two clutch design on the main gear. Main gear disengages from the chain during riding which makes it to ride your bicycle like a mechanical one. The older version (The TSDZ2) only had one clutch design.

Whether you're cruising around town or climbing a steep hill, this motor gives you the boost you need to get where you're going. And because it's a mid-motor design, it's perfect for those who want a more balanced ride. So if you're looking for an electric bike conversion kit that can keep up with your active lifestyle, the TongSheng Mid Motor is the perfect choice.

We also provide a set of spacers to help you adjust the motor to fit your bike.
