Trek Powerfly FS+ 4 800Wh Gen 4 Electric Mountain Bike 2026
The Powerfly FS+ 4 800W is a full-power full suspension electric mountain bike for taking on alpine adventures. Its powerful Bosch motor gives you a boost for soaring up climbs, while a massive 800 Wh battery keeps you going through your longest adventures. A RockShox suspension package (120 mm rear, 130 mm front) smooths out rough trails, while a 10-speed Shimano CUES drivetrain delivers clean-shifts for any kind of trail.
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.
Adventure-ready accessories
The Powerfly Equipped gives you maximum utility thanks to pre-installed accessories. You get a kickstand, front and rear lights, plus mudguards and a rear rack custom made for clean integration.
Bosch eBike Flow app
The new eBike Flow app turns your ride into a personalised experience. Use it to customise your motor's assist behaviour, 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.
Shimano CUES
Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano’s new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette and chainrings.
Shimano LINKGLIDE
LINKGLIDE technology has been specifically engineered for incredible durability while still delivering smooth and decisive shifting – along with a great pedalling experience. Available exclusively on Shimano CUES drivetrains.
