The Powerfly+ 8 is a rugged full-power hardtail electric mountain bike that's made to conquer your every adventure. Its sturdy alloy frame makes it a versatile choice anywhere from alpine trails to urban exploration, and the powerful Bosch Performance Line CX motor gives you the boost you crave when the track ahead gets steep. It comes ready to roll with parts that make a difference, like Tubeless Ready wheels, a dropper post and an upgraded Shimano SLX and XT blend drivetrain.
