Powerfly 4 is our most affordable electric mountain bike. It's built with parts that hold up, like a smooth-shifting Shimano drivetrain, and a powerful Bosch motor. Plus, it features our user-friendly Removable Integrated Battery (RIB) system that's fully encased in the frame yet doesn't require tools for removal. This bike expands your boundaries and lets you travel to destinations you never thought you'd reach on a mountain bike.
