Change the pace
Working alongside one of the world’s leading F1 engineers we have developed a system that harnesses power from an ultra light-weight battery and channels it through a precision-engineered, light-weight motor.
From the pit lane to the Col de la Madone.
HPS harness a deep understanding of the tradition and passion of cycling, combined with F1 precision engineering.
The world’s lightest e-bike motor system, unique by design
We use swiss-engineered components, designed to be used in the most extreme conditions. WATT ASSIST Pro has been developed to the highest standards and rigorously tested in state-of-the-art laboratories. The result is an elegant and compact bottom bracket shell that seamlessly integrates into the frame, housing our light-weight motor system… without compromise.
Key Features
ground-breaking weight
Almost no weight restriction. Balance, weight distribution and handling are not effected by WATT ASSIST Pro.
Wheel options
Unlike some e-bike motors, WATT ASSIST Pro has been designed without compromise, so you can swap out wheels with our Domestique® bike, and change them as often as you want.
The road bike, amplified
No other e-bike comes close to the ride qualities of Domestique®, it delivers the ride characteristics and low weight of a high-end road bike, with the perfect amount of power when you need it.
HPS-sync
There are infinate options to fine tune your HPS Domestique® bike using our control app. An integrated power meter keeps track of your power, giving you the ultimate training tool – use WATT ASSIT Pro for zonal training, adding power when your heartrate raises.
