The TQ HPR50 e-bike system
The lightest, quietest and smallest e-bike system in its class. The perfect features for more uphill and downhill riding. The TQ-HPR50 brings bikes to life, letting you have more fun without having to compromise – Advanced, Naturally! TQ takes care of the technology so you can enjoy your ride!
At the heart of the system is the 1,850 g HPR50 drive, delivering 50 Nm of torque, featuring patented Harmonic Pin-Ring technology. Combined with the 360 Wh battery, the fully integrated 2-inch display and the minimalist remote unit, this creates the lightest e-bike system in its class, with a total weight of 3,900 g. The entire system is designed to maximise your riding enjoyment without drawing attention to itself.
Technology for the most natural riding experience
The Harmonic Pin-Ring gearbox, or ‘HPR’ for short, is the result of TQ’s decades of experience in developing electric motors. A drive system used in robots, satellites and even Mars rovers. By further developing the patented Harmonic Pin-Ring technology, a drive gearbox has been designed that enables a seamlessly integrated, silent e-bike system.
Conventional mid-drive e-bike motors consist of an electric motor and a combination of gears and planetary gearboxes, which makes them bulky, heavy and noisy. At the same time, more moving parts also mean more things that can break and act as sources of noise.
Thanks to the revolutionary HPR gearbox, TQ is able to build a lightweight and extremely compact motor design around the bottom bracket, consisting of just a few individual parts and making the motor virtually invisible. By eliminating additional gears – which cause friction, noise, wear and potential sources of failure – the drive unit has been made even more efficient. The result is e-bikes that sound, look and ride just like conventional bikes – and are ultimately better! It’s technology you can feel. It’s Advanced, Naturally!
Display
The DISPLAY – elegantly integrated into the frame – is the control centre of your e-bike. Even in the most adverse lighting conditions, all key information – such as battery status, the selected riding mode, available range and much more – can be read clearly. Using the ANT+ sensor, you can easily connect your smartphone or cycle computer to the bike.
Remote
With the handy REMOTE, you have full control over the HPR50 system without having to take your hands off the handlebars. It’s intuitive and easy to use, and you can switch between three assistance modes as well as the information displayed. Should the going get particularly steep, Walk Mode will assist you over the final metres to the summit.
Battery
The BATTERY, with a capacity of 360 Wh, was specially developed for the HPR50 Drive Unit and combines maximum efficiency with a compact design. Weighing just 1,830 g, it allows you to retain the dynamics and appearance of a conventional bike.
Range Extender (optional)
About the size of a 500 ml water bottle, the 900 g RANGE EXTENDER fits elegantly into the frame of your e-bike and fits into any standard bottle cage. Thanks to the Dual Charge Port, it can be charged alongside the battery without having to be removed from the frame first. With a capacity of 160 Wh, it has enough power to turn your after-work laps into epic all-day rides.
