Trek Powerfly FS+ 6 Gen 4 2026

Description

The Powerfly FS+ 6 is a full-power full suspension electric mountain bike built to explore beyond the beaten track. Its Alpha Platinum Aluminium frame blends confident geometry with a FOX suspension package (120 mm rear, 130 mm front) to smooth out rough trails. It comes ready to roll with a 12-speed Shimano XT/SLX drivetrain and the serious stopping power of Shimano 4-piston M6100 hydraulic disc brakes.

It’s right for you if…

Are you itching to get far, far out there? The Powerfly FS+ is your dream ride. This fully-capable e-MTB takes you beyond the beaten track with the trail-smoothing benefits of a full suspension mountain bike for rough roads and light singletrack, and tons of power to make the ups just as much fun as the downs.

The tech you get

An Alpha Platinum Aluminium frame with a Bosch Performance Line CX motor (85 Nm, 250 W), a huge 800 Wh PowerTube RIB 2.0 removable integrated battery and Purion 200 controller. 130 mm front and 120 mm rear suspension from a FOX Float AWL fork with an air spring and RAIL 2.0 damper and a FOX Float Rhythm shock. Tubeless-ready wheels with puncture-resistant 2.4 tyres, a 12-speed Shimano SLX drivetrain for clean shifts, a Bontrager Line dropper post and hydraulic disc brakes.

The final word

The Powerfly FS+ 6 is an electric mountain bike built for discovering what’s beyond the next climb. It features just enough trail-smoothing suspension to boost comfort and confidence, and plenty of power to get you wherever you want to explore.
