Power Transmission
for Bicycles
Your Drive System Must Make the Most of Every Watt Delivered by the Motor
Your e-bike requires a complete, reliable drivetrain capable of converting every watt produced by the motor into effective propulsion, without unnecessary losses. A poorly designed transmission wastes energy through friction and increases the number of wear components that require replacement. At the same time, demand for French-made drivetrain solutions continues to grow across the electric mobility market.

Our Belt Drive Solutions
Drivetrain System for E-Bikes
We are developing this solution as part of our eBDC France project, recognized through the ADEME innovation program. This complete, next-generation drivetrain is designed and manufactured in France, strengthening our position within the electric mobility value chain. It also contributes to reducing greenhouse gas emissions while promoting local sourcing and shorter supply chains.
Ribbed Belts
Ribbed belts transmit torque through multiple longitudinal ribs rather than a single large contact section. This architecture allows for smaller pulley diameters, a major advantage within the limited space available inside a bicycle frame. As the inventor of the ribbed belt concept, we remain a recognized expert in the calculation-based design and specification of these transmission systems.
