TQ-HPR50 small, quiet, mighty

The TQ-HPR50 motor is super-efficient with an amazing power-to-weight ratio. Most motors use gears and belts that take up space and can make noise or break. The TQ-HPR50 uses a harmonic pin-ring drive transmission thats small, ultra-quiet and unbelievably natural-feeling.

Removable battery
