It's finally here: the 48V 500W(nominal) 700W(peak) Tongsheng torque sensored mid motor.

What makes this little motor incredible?

  • Supports up to 58.6V input voltage (hence the TSDZ2B version. Regular TSDZ2 only supports up to 45V peak)
  • Fits 95% of standard bike frames with 68-73mm bottom bracket
  • 30% lighter than a Bafang motor for almost the same power output
  • Built in torque and cadence sensor - this results in much smoother acceleration than any cadence sensored mid motor
  • Easy to install. Kit includes all installation hardware and tools
  • The motor has an extra support mount - resulting in a much more reliable install than a Bafang BBS motor
  • No throttle - this system is a pure pedelec; motivating you to pedal harder and go farther
  • 80Nm of torque is almost twice as much as a hub motor and can help you climb up any hill in your way
