Compact, powerful - and flexible utilization

The secret of the small power package lies in our combination of the patented TQ Harmonic Pin Ring transmission with the electric motor developed specially  for e-bikes. With a torque of 120 Newton meters, the TQ HPR 120S is unique in its class and, with a diameter of only 144 millimeters, offers the highest torque within the smallest of spaces.

The advantage is always noticeable: the high torque makes an e-bike both more comfortable and more powerful to use. Because the higher the torque, the lower the cadence can be achieved with the same power. This goes hand in hand with a higher power bandwidth, so you don’t have to shift as much. Last but not least, the higher torque also enables more peak power at a higher cadence, which makes riding a lot more fun.

The powerful TQ drives are the result of joint development work and have been in use at M1-Sporttechnik, the first e-bike manufacturer to use them, for over 5 years. Together with our self-developed batteries, our drive system is unrivalled thanks to high-tech sensors.
