“F8.11” is a revolutionary invention born to ensure maximum control, comfort and efficiency and is the first ever to come directly from an e-bike concept. It’s a patented sequential electronic gearbox with rotary shift and auxiliary motor built into the gearbox. This system gets rid of any transverse movement inside or outside the motor/gearbox. Full protection is guaranteed by the stress sensor with strain gauge technology to measure torque between primary (chainrings) and secondary gears (sprockets).
