Aluminium full-suspension electric mountain bike Trek Powerfly+ FS 6 blue: Bosch CX 800 Wh, Fox 36 140 mm, 25.08 kg

Trek Powerfly+ FS 6 Mulsanne: the Fox 36 for a more playful e-MTB

This version of the Trek Powerfly+ FS 6 gets a 140 mm Fox Rhythm 36 fork from size M, a SRAM Eagle 70 T-Type drivetrain and a 0° stem, for sharper handling. Bosch CX motor, 800 Wh battery and 120 mm Fox Float Rhythm shock: it weighs 25.08 kg in size M according to Trek. Its Mulsanne colourway is a deep, intense blue.

Technical specifications

Who is it for?

For the mountain biker who likes to play with the terrain, pop off small bumps and link corners together, while keeping an e-MTB capable of big rides. It will appeal to anyone who wants a sturdier fork without moving to an enduro bike.

The LVR workshop view

The UDH hanger, discreet but valuable. The UDH hanger, an open derailleur mounting standard, is this frame's discreet asset: it takes the SRAM T-Type drivetrain directly with no intermediate hanger, and is easy to replace after a knock. For the rest, the Alpha Platinum aluminium, the motor protected by the Motor Armor cover and the removable RIB 2.0 battery form a tough base, built to be ridden often.

Put simply: this FS 6 gets tougher up front with a 140 mm Fox 36 from size M and a 0° stem, while keeping 120 mm at the rear. It weighs the same as the FS 6 with Fox AWL fork and Shimano drivetrain (25.08 kg in M): the difference is in the ride, not on the scales.

The Fox 36, with its 36 mm stanchions, Float EVOL spring and GRIP damper, delivers remarkable steering precision in rock gardens and hard-loaded corners. The 0° Rhythm Comp stem lowers the front end slightly, which helps keep weight on the front wheel on steep climbs and in corners alike.

The SRAM Eagle 70 T-Type drivetrain mounts directly to the UDH hanger and offers a very wide-range 10-52 cassette. The Bosch CX assist complies with European rules: 250 W nominal, help cutting out at 25 km/h. Updates are done via the Bosch eBike Flow app.

Which Powerfly+ FS should you choose?

Our take: at the same weight (25.08 kg in M) as the FS 6 with Fox AWL and Shimano, this version gains a 140 mm Fox 36 and the T-Type drivetrain. The FS 8 with XT Di2 steps up to 150 mm for 24.88 kg.
