Why is TONGSHENG Mid Drive?
Torque Sensing
The TSDZ2B 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 (3.5KG) for eMTB
Additionally, the TSDZ2B is lighter than the BBS02, making it a preferred choice for those aiming to maintain a lightweight bike after conversion. Moreover, the TSDZ2B 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
The TSE (TONGSHENG) motors are designed to fit into bottom brackets following the JIS or similar standards such as ISO/English, BSA (British), or threaded types commonly found in the US. These motors have a bottom bracket shaft diameter of 33.5 mm and are available in widths of 68 mm, 73 mm.
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.
HAILONG G80
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
It comes with a red LED tailight, our tailight is the option if you can not find a battery that fits to your frame or you want to get a second battery to very extend the range of your e-bike.
