FSA System HM 1.0, the first FSA’s e-bike drive system officially presented at Eurobike last year, is ready for the mass production and will be available for bike frames producers early September.



"The new FSA System HM 1.0 represents the culmination of intensive and unrestrainable R&D and of more than a decade of market research and experience in the e-bike segment having worked as drivetrain partner with many established motor system producers. Likewise, we have supplied drivetrain components for e-bikes to brands including Bianchi, Focus, Pinarello, Cube, KTM, Fantic and Scott, among many others” says Davide Riva, FSA Europe OEM Sales manager & Prod.

The complete system has been developed by FSA in Italy as well as the production of the batteries and battery management system, while deliveries and stock for the market are handled by FSA from its headquarters located in Europe, North America and Asia. “This gives us the opportunity to be very flexible and supply small to medium-size customers,” continues Davide Riva.

The “FSA System” comprises of a rear hub electric-assist motor, a 250Wh battery unit, a further 250Wh expansion battery, with an integrated on-bike control unit.
The compact design and low weight (a full system weighs just 3.98 kg) ensures a sleek integration with e-road, e-gravel and commuter bikes, with a 20-cell, 250Wh battery unit that integrates completely inside the downtube, and an additional 250Wh battery installable within a bottle cage for longer rides. The system is completed with an assistance remote control that integrates into the top tube, and an easily-accessible charge port situated above the bottom bracket.

There are five assistance settings, including an ‘eco’ Green and ‘boost’ Red mode, serving up to a maximum of 250W and 42Nm of torque, while the motor itself features an integrated torque sensor and two-speed sensors, which can adapt easily to different riding styles and changing conditions. When exceeding the EU-mandated limit of 25km/h for electrical assistance (32km/h for the USA), the “FSA System” hub shuts down and presents minimal friction and resistance to the drivetrain, allowing the rider to experience a natural and free pedalling motion. Together with the low total weight and compact integration of the system, as well as a low Q-factor, exactly like on a road bicycle. This allows the e-bike to handle as close to an ordinary pedal-powered bike as possible and can fit XS-sized bike frames and all geometries.

“We have designed our motor system to last, utilising our class-leading expertise in drive train component production. The hub features superior bearing life thanks to our leading know-how in component manufacture, as well as highly resilient waterproofness that helps to ensure long maintenance cycles” concludes Davide Riva.

A dedicated app for FSA System has been developed, available for both iOS and Android devices, which will enable the rider to record ride and usage statistics, display remaining battery life and charge status, as well as feature full GPS turn-by-turn navigation. The app also features a diagnostic centre, complete with chatbot interaction and the facility to communicate directly with FSA’s service centers worldwide. 


There are four accompanying wheelsets that have been developed to incorporate the “FSA System” hub: the Vision Metron 40 SL Disc, Trimax 30 Disc, Team 30 Disc and AGX gravel-specific wheelsets. Further wheelset options are already in development, which will ensure that we offer a complete range of wheels for e-road and e-gravel use.
