There are lots of new shifting and drive train options coming from the FSA camp at Eurobike 2022. First was the updated K-Force WE 12-speed groupset, and now E-System; a rear hub electric-assist motor.
The E-System looks to be an OEM-only option we could see popping up on the road, gravel, and commuter ebikes for the upcoming year.
FSA E-System — What is it?
FSA System’s E-System boasts a total of 500Wh (250Wh battery unit + 250Wh RE). The 20-cell, 250Wh battery unit integrates entirely inside the frame. Riders can install the extra 250Wh battery in a bottle cage for longer rides.
Like most ebike systems, E-System has an LED HID push button that integrates into the top tube and an accessible charge port above the bottom bracket.
FSA E-System — What are the ride settings?
There are five assistance settings, one that is neutral and four that are active. The motor features an integrated torque sensor and speed sensors, which FSA claims can adapt to different riding styles and changing conditions. The new FSA E-System boasts a smartphone app with integrated on-bike control for those looking to keep both hands on the bars. The E-System is fully compatible with the Garmin ebike remote and appears to use a band-style strap for easy on/off.
How fast will it go?
FSA explains, “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.”
Does it sound like a motor?
The new flex for ebike motors is the volume output, and the new E-System is relatively quiet, outputting less than 55 decibels.
When will we see it on bikes?
We’re going to have to wait and see. Right now (as everyone knows), the stock is the name of the game, and if you have it, bike manufacturers will spec it. It’s uncertain if we will see this many bikes in North America, but I would bet the European market could see it soon, especially with the high demand for ebike components.
FSA E-System Hub/Motor
The FSA E-System motor adopts an integrated torque sensor with a linear response. It has continuous and stable power and can automatically adjust the speed, ample starting torque, climbing assistance, and anti-brake blocking solid ability. There are reports of the FSA E-System on road and gravel frames that look like 12×142 spacing, but the final spec will most likely be up to the bike manufacturer.
