FSA (Italy) - Press Release: We are proud to announce the forthcoming launch of our brand new e-bike motor system, the “FSA System”. 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 and smartphone app.

FSA is already the leading provider of e-bike transmission components including cranksets, spiders and sprockets, and the new motor system represents the culmination of more than a decade of research and experience in the e-bike market, having worked as drivetrain partner with many established motor system providers, including Bosch, Brose, Fazua, Polini and Yamaha. Likewise, we have supplied drivetrain components for e-bikes to brands including Bianchi, Cube, Focus, KTM, Pinarello and Scott, among many others.

FSA System’s compact design and low weight (a full system weighs just 4.0kg) 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, while the motor itself features an integrated torque sensor and two speed sensors, which can adapt easily to different riding styles and changing conditions. It provides extremely responsive yet consistent assistance, and is quiet, outputting less than 55 decibels.

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 pedaling 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.

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 center, complete with chatbot interaction and the facility to communicate directly with FSA’s service centers.

At launch, 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.

We have designed our motor system to last, utilising our class-leading expertise in drivetrain 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, reducing the need for servicing. The FSA System is easy to maintain and install, while our network of 40 service centers worldwide supplies comprehensive technical support for dealers and end users.
