2023 Review of the new Trek Powerfly 4 GEN4 vs. Trek Powerfly FS4 GEN3 vs. Trek Powerfly FS9 GEN3 Trek keeps pumping out the Powerfly electric bikes and each year they keep getting better, with Bosch Smart System and Sram AXS shifting this is the ultimate model!
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.
The Trek Powerfly FS 4 and Trek Powerfly FS 9 Equipped are both 27.5″ / 29″ aluminum frame full suspension crosscountry e-bikes. The Powerfly FS 9 Equipped has better components, a better fork, and a 1 × 12 drivetrain providing a wider range of gears.
