The Powerfly+ FS 4 is a full-power, full-suspension electric mountain bike ready for high-altitude adventures. The powerful Bosch motor propels you up the steepest climbs, while the generous 800Wh battery supports even the longest rides. The RockShox suspension package (130mm front and 120mm rear) smooths out even the toughest trails, while the Shimano CUES 10-speed drivetrain ensures smooth shifting.
