Why is TONGSHENG Mid Drive?

Torque Sensing

The TSDZ8 mid-drive motor offers several advantages over the Bafang BBS02 that appeal to electric bike enthusiasts seeking a more natural riding experience and customization options. One of the primary advantages is its torque sensing capability, which allows the motor to not only detect pedaling but also gauge the rider's effort and adjust power output accordingly. This feature provides a more intuitive and responsive ride compared to the constant power delivery of Bafang motors.

Lightweight () for eMTB

Additionally, the TSDZ8 is lighter than the BBS02B, making it a preferred choice for those aiming to maintain a lightweight bike after conversion. Moreover, the TSDZ8 is available in a coaster brake version, making it compatible with coaster brake bikes, which other mid-drive or rear hub motors cannot accommodate. This expands the range of bike options for electric conversion, enhancing the potential for enjoyable rides.

BBS Measurement

HAILONG Downtube Battery

Smaller battery can be better used in the smaller bike frame. All battery comes with the upgraded 30A BMS for multiple protection. The 4A fast charger save half charging time.


Larger downtube battery extend range and also reduce charging times, extend battery life in other word. If your bike frame is large enough to accommodate a larger battery, we highly recommend the Hailong G80.

Rear Rack & Battery
