Trek Powerfly 4 Us 27.5 2021

Powerfly 4 is our most affordable electric mountain bike. It’s built with parts that hold up, like a smooth-shifting Shimano drivetrain, & 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 & lets you travel to destinations you never thought you’d reach on a mountain bike.
