FSA launches hub drive e-bike system

Published September 16, 2019

FRIEDRICHSHAFEN, Germany (BRAIN) — Taiwanese component giant FSA has launched its first e-bike motor system, called the FSA System. 

The system includes a rear hub motor, a 250Wh battery unit, a 250Wh expansion battery, and an integrated on-bike control unit and smartphone app.

FSA is a major provider of e-bike transmission components including cranksets, spiders and sprockets. The company said 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."

FSA's full system weighs 4 kg (8.8 pounds) and is designed for e-road, e-gravel and commuter bikes, with a 20-cell, 250Wh battery unit that integrates inside the downtube, and the 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 a 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 has an integrated torque sensor and two speed sensors, which can adapt to different riding styles and changing conditions. The company said the system is quiet, producing a maximum of 55 decibels.

When exceeding the 20 mph, the motor shuts down; FSA said the motor presents minimal friction and resistance to the drivetrain when shut down. FSA said, "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."

At launch, FSA offers 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.

"We have designed our motor system to last, utilizing 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.
