Empowered

Our Propulsive Module technology is more than a motor. Meet our all-in-one dual motor system with electric assistance and a stepless automatic gear shift.

Enjoy seamless shifting and reactive assistance, even at standstill or when pushing hard. Wherever you’re at, you’ll maintain a comfortable cadence.
Automatic electric driving gets safer, smoother and more fun

No more complex gear shifting, just high mileage with low maintenance. Keep your head free to focus on the road, not on your bike.

Gen 1
Propulsive
Module

Generation 1. The groundbreaker. It’s quiet, smooth, and efficient, making the Gen 1 Propulsive Module perfect for trekking and city use.

Dual belt drive
The internal transmission is made of two synchronous belts, providing a smooth and silent operation.
Planetary gearset
The heart of the system: combining human input with the power of electric motors to produce a stepless automatic gearshift.
Dual Motor
The operation of both motors is continuously adjusted. This gives you any combination of support level and gear ratio, for a smooth and tailormade ride.
Single PCB
Both motor driver components and the 8 sensors are gathered on a single board for a neat and cost effective integration. It houses a powerful microcontroller operating a motor control 20.000 times per second
