The Powerfly FS 4 is a full-suspension electric mountain bike that's eager to hit the trail. It packs in plush suspension to soak up rough-terrain and a powerful Bosch drive system to boost your capacity to crush long climbs and mile after mile of singletrack. It's equipped with Bosch's latest LED remote and Purion display that pair with the eBike Flow app to give you activity tracking, navigation and Bluetooth connectivity.

You want to boost your mountain biking capabilities with a high-end pedal-assist system. You plan to hit the trail often, and want an upgraded parts spec that'll help you push your limits.

A durable aluminium frame with an ultra-user-friendly Removable Integrated 625 Wh Battery, a powerful Bosch Performance CX (250 Wh, 85 Nm) motor that helps you sustain speeds of up to 20 mph (25 km/h in Europe) and a smart system LED controller and Purion display. Plus, an SR Suntour 100 mm suspension fork, 100 mm of rear travel, a 9-speed Shimano CUES drivetrain, powerful hydraulic disc brakes and a dropper post.

This full-suspension e-MTB boosts comfort and capability on the trail with just the right amount of power to get you through long miles and up steep climbs. Its suspension package cushions rough trails so you can comfortably reach new destinations.
- The Powerfly FS Gen 3 features Bosch's smart system with an LED remote that connects to the Bosch eBike Flow app for over-the-air system updates, customised motor tuning and more
- 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 really 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
- 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

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
The Bosch Performance Line CX sets the standard for eMTB performance with up to 85 Nm 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 centre 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 completely 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.
