TQ HPR® 120S - Lots of power in a little space
The secret behind this powerful little motor is the combination of a patented TQ harmonic pin ring drive combined with an electric motor specially developed for E-bikes. Another unique aspect: With torque of 120 newton meters, the TQ HPR® 120S is in a class all its own. And with a diameter of just 144 millimeters it’s small enough to be easily built into to any bike.
