Product Info

Powerfly FS 4 is a full suspension electric mountain bike built to tackle rugged trail adventures. The plush suspension setup soaks up rough terrain, and the powerful Bosch electric drive system boosts your capacity to crush climbs and mile after mile of singletrack.

  • For e-MTB, full suspension is a game-changer: it soaks up rugged terrain so you can ride the Bosch pedal-assist smart system to its full potential
  • Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy to remove the battery without tools, and lets you mount a water bottle cage—even on full suspension e-MTBs
  • The dropper post lets you lower your saddle on the fly so it's out of the way on descents
  • It comes equipped with Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
  • Powerfly FS frames feature a curved top tube that makes standing over the bike easier. Plus, Smart Wheel Sizing means you'll get the fastest wheel that fits—29˝ wheels on larger frames, 27.5˝ wheels on smaller frames
  • You want to get out and explore more trails. You're looking for an e-MTB with trail-smoothing full suspension and the reliable, leg-boosting power of an electric drive system made specifically for the demands of off-road riding.
  • A durable aluminum frame that fully encases a long-range 500Wh battery. The latest from Bosch with smart system Performance Line CX motor, capable of speeds up to 20MPH, including the new Bluetooth® LED remote for easy connectivity and all-in-one navigation and activity tracking through the eBike Flow app. Plus, a 120mm suspension fork, 100mm of rear travel, a 10-speed Shimano drivetrain, and a dropper post.
  • This full suspension e-MTB is comfortable, efficient, and fast on rough terrain. The powerful Bosch electric drive system makes it possible to tackle any climb you encounter and adventure farther than ever.

  • Removable Integrated Battery

      RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security, or just easier charging.


    Bosch Performance Line CX motor

      Bosch Performance Line CX sets the standard for eMTB performance with up to 85Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.


    Bosch LED Remote

      The Bosch smart system LED remote lets you easily change assist modes, activate walk mode, or turn on optional lights. The bright LEDs are easy to see in any light, and show you your battery level and assist mode at a glance.


    Bosch Intuvia 100 display

      The Bosch smart system Intuvia 100 display puts your ride data front and center with a large-font high-contrast display that's easy to read in any weather. You get eBike Lock theft protection, and best of all, it's completey wireless and connects to the remote via Bluetooth.


    Active Braking Pivot

      Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.


    Bosch eBike Flow app

      The new eBike Flow app turns your ride into a personalized experience. Use it to customize your motor's assist behavior, track your ride stats, and integrate your data with apps like Strava and Apple Health. There's even handy features like navigation and service reminders.
