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

Battery choices:

52V 7Ah:  this is the smallest battery pack we have. It fits under the seat of your bike. More information on this battery is available HERE

48V 13.2Ah:  These are made with Samsung 33G cells in a 13 series, 4 parallel configuration. More information on this battery is available HERE
52V 14Ah: These batteries are suitable for 48V systems. These are made with Panasonic/Sanyo GA cells in a 14 series, 4 parallel configuration. The advantage of a 52V over a 48V system is that when the battery is almost empty, the voltage drop won't be as low as a 48V battery, so you will notice more usable range out of a 52V battery. That being said, the drawback of a 52V system is that a lot of 48V motor manufacturers may void warranty if used on a 52V system. More information on this battery is available HERE

 

52V 17Ah: These batteries are suitable for 48V systems. These are made with Panasonic/Sanyo GA cells in a 13 series, 5 parallel configuration. More information on this battery is available HERE
