Revolutionary WATT ASSIST™ Powering your ride.

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.

Key features

The bike is a beautiful thing. We worked tirelessly to maintain the classic lines of a racing bike, without compromise.

Almost no weight restriction. Balance, weight distribution and handling are not effected by the HPS systems.

Watt Assist™ provides a natural feel for riders. It will give you that ‘good day’ on a bike feeling.

35% Advantage with HPS

"This can get addictive"

Using HPS Domestique™ rider Leon Pacini gains a 35% advantage on his local mountain climbs in Monaco, and finds riding with Watt Assist™ pushes him to ride harder and faster, upping his average heart rate by 6bpm while riding.

The world’s lightest bike power assist system, unique by design.

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 and gear box.

We use swiss-engineered components for use in the most extreme conditions. The HPS system has been developed to the highest standards and rigorously tested in their state-of-the-art laboratories.

The result is an elegant and compact bottom bracket shell that seamlessly integrates into any frame, housing our light-weight motor system… without compromise.

Ride like a pro. See what happened when we gave Formula1 legend David Coulthard a WATT ASSIST™ powered bike and let him ride with former Road Race World Champion, Tom Boonen.

Full integration

HPS features ANT+ technology which communicates with Garmin and other fitness displays without wires.

Integration is seamless – Garmin displays the HPS power mode and can be used to change power setting if desired. Battery power level display will be integrated soon.
