Who is it for?

For the demanding mountain biker who wants precise electronic shifting, a colour display and a generous fork for descending. It suits regular riders who head out often and far.

The LVR workshop view

Three adjustments to get the most from the 150 mm fork. What this frame brings to the FS 8 is adaptability: Mino Link for geometry, an adjustable ratio for progression, and the ABP pivot to keep the rear active under braking. With a 150 mm fork, these adjustments really come into their own, as they let you balance a more generous front end with the 120 mm at the rear.

	Alpha Platinum (Powerfly+ FS)	Alpha NEXT Platinum (Fuel+ EX 8)	OCLV Mountain (Rail+ 9.7 / 9.8)
Level	High-end Powerfly e-MTB aluminium	Trek's most advanced alloy	Trek mountain bike carbon
Construction	Mino Link, adjustable ratio, ABP	Tubes optimised to the gram	OCLV carbon main frame
Reference bike	Powerfly+ FS 8, 24.88 kg (M)	Fuel+ EX 8	Rail+ 9.8, 23.98 kg (M)
What it means	Fine adjustment, a bike built to last	Lighter, TQ motor	900 g lighter than this FS 8

Put simply: this FS 8 pairs a 150 mm Fox 36 with the only Shimano XT Di2 drivetrain in the Powerfly+ FS range. At 24.88 kg in M, it is 400 g heavier than the FS 8 with SRAM AXS drivetrain and 130 mm fork, the price of its longer fork and its equipment.

The Shimano XT Di2 M8260 shifts electronically, with consistent precision whatever the mud or dust. The wireless derailleur means no cable housing to maintain, and the bar-mounted shifter has a very light action. We take care of setup and updates in the workshop.

The 150 mm Fox Rhythm 36, with its GRIP damper, offers a solid, precise front end, ideal on the steep trails of the Caroux. The Bosch assist stays limited to 25 km/h and 250 W nominal, as on all European e-bikes, and the Kiox 300 is updated via the Bosch eBike Flow app.

Which Powerfly+ FS should you choose?

Model	Motor / battery	Rear / front travel	Drivetrain	Weight (M)
Powerfly+ FS 6 (Fox 36)	Bosch CX / 800 Wh	120 / 140 mm	SRAM Eagle 70 12-speed	25.08 kg
Powerfly+ FS 8 (GX AXS)	Bosch CX / 800 Wh	120 / 130 mm	Wireless SRAM GX AXS	24.48 kg
Powerfly+ FS 8 (XT Di2)	Bosch CX / 800 Wh	120 / 150 mm	Wireless Shimano XT Di2	24.88 kg
Rail+ 5	Bosch CX / 800 Wh	160 / 160 mm	Shimano Deore 12-speed	24.78 kg

Our take: at 24.88 kg in M, this FS 8 weighs 400 g more than the FS 8 SRAM AXS, but offers 150 mm up front. The Rail+ 5 (24.78 kg) steps up to 160 mm front and rear for enduro.

LVR sizing advice

With a 150 mm fork and a 0° stem, this FS 8 keeps a fairly high front end: between two sizes, the smaller one stays agile without losing comfort. The S rolls on 27.5-inch wheels with a 100 mm dropper.

Size	S	M	L	XL
Rider height (cm)	155-165	165-177	177-188	188-195
Inseam (cm)	74-78	79-83	84-89	89-91
Dropper post (mm)	100	170	170	170
Wheels (in)	27.5	29	29	29
