The Powerfly+ FS 4 is a powerful, full-suspension e-mountain bike that doesn't shy away from adventures in the mountains. Trails are softened by a suspension system with 130 mm of front travel and 120 mm of rear travel, and the robust Bosch Performance Line CX motor, paired with a removable, integrated RIB 2.0 battery that is compatible with an additional Bosch PowerMore battery, takes you far out there.
