TQ-HPR50 E-Bike System

TQ-HPR50 - the e-bike system for the most natural riding experience

The TQ-HPR50 Drive System is much more than just a drive system for e-bikes - it's the beginning of a whole new riding experience. Thanks to the lightweight and completely integrated system, the extremely quiet motor and the most natural riding experience in its class, you'll forget you're riding an e-bike. That's exactly what we've achieved at TQ. A drive system that makes your e-bike look, sound, and most importantly, feel like an analog bike. Only better!

Advanced, Naturally

The lightest, quietest and smallest system in its class. The TQ-HPR50 creates mountain bikes that let you climb every mountain and clock even more downhills. It brings bikes to life that let you have more fun without having to compromise – Advanced, Naturally. We take care of the technology so you can enjoy the ride.

Most silent in its class

Out on your ride, the extremly quiet motor lets you hear what you want to hear – the sounds of nature.


Most natural ride-feel

The compact shape, low weight and finely-tuned motor let you forget that you’re riding an e-bike. It’s the same riding experience as with an analog bike – with the pedal assistance of an e-bike.

Lightweight champion

The low weight turns your bike into an absolute handling-machine that not only lets you conquer the narrowest trails and sharpest hairpins, but also master the steepest climbs with ease.
