A DIY mid-drive conversion kit built around TongSheng's BBS02B and BBS-HD motors in 500W, 750W and 1000W versions, with 100, 120 or 160 N·m of torque depending on the motor. The kit includes brake levers, chainrings, thumb throttle, speed sensor, headlight and bottom bracket removal tools, and the battery and display are optional. It fits 68–73 mm, 100 mm and 120 mm bottom brackets with a 33.5–36 mm inner diameter on chain-drive bikes with disc or V-brakes. Compared with hub kits it keeps weight central and drives through the gears, so it climbs better, but it costs more and installs with more work.

Owners of TongSheng mid-drive kits generally report strong climbing and a natural ride through the gears, and praise the completeness of the accessory bundle. Complaints center on installation friction, missing fasteners and the cadence-based assist.
This mid-drive conversion kit turns a standard bicycle into an electric bike. It is a TongSheng CAN bus mid-drive motor kit (BBS02B/BBS-HD) with a 48V, 1000W rating. A battery and a display are optional.
The kit includes brake levers, chainrings, a thumb throttle, a speed sensor, a headlight and bottom bracket removal tools. It fits bikes with a chain drive and either disc brakes or V-brakes, such as mountain bikes, city commuter bikes and recumbent tricycles.
The motor has three riding modes: throttle, pedal assist and standard riding. Top speed is up to 45 km/h. It works with TongSheng batteries and with the 48V e-bike batteries offered with it. If you choose the no-battery option, you need to supply a compatible 48V battery.
