Full Speed Ahead just announced their new FSA System e-bike motor. Meant for road, gravel & commuter bikes, the rear hub drive unit provides a maximum of 250 watts of assist, pulling from a 250Wh battery inside the down tube. Additionally, you can add an second 250Wh battery into a bottle cage for extra range.
2020 FSA System e-bike pedal-assist rear hub motor
E-bike systems are on the rise, and FSA just joined the fray. They were already a supplier of cranksets, spiders, and sprockets to other e-bike manufacturers, and opted to make their own complete system. It’s somewhat reminiscent of the Fazua Evation setup, in that it targets low weight (4kg total), and gets a hidden downtube battery. However, rather than using a bottom bracket motor, it drives a large rear hub that must be built into your wheel.
FSA will offer four initial wheel options: Vision Metron 40 SL Disc, Trimax 30 Disc, Team 30 Disc, and the AGX gravel-specific wheels. That’s another big reason for FSA’s choice of a hub motor, since they can already build it into their Vision brand of wheels, and offer complete wheelsets.
The motor will have five output settings, hitting a maximum output of 250W of pedal assist (and a maximum noise level of 55 decibels). The 20-cell downtube battery has 250Wh of storage capacity, and there’s an optional bottle cage auxiliary battery with the same capacity(not pictured) – very reminiscent of the Range Extender in the latest Specialized e-system. The battery charge port is near the bottom bracket area, and doubles as the power port for the extra battery.
