Trek Powerfly+ FS 5 Blue Sage: 12 speeds and 800 Wh, the sweet spot

The Trek Powerfly+ FS 5 is an aluminium full-suspension electric mountain bike that bridges the gap between the FS 4 and FS 6: Bosch CX motor, 800 Wh battery, 12-speed Shimano drivetrain with XT 10-51 cassette and four-piston Shimano MT620 brakes. It runs 120 mm at the rear and a RockShox Psylo Silver RC fork, for 24.58 kg in size M according to Trek. The Blue Sage/Catalina Fog colourway pairs a sage blue-green with a deeper teal.

Who is it for?

For the mountain biker who wants an e-MTB that can progress with them, with a 12-speed drivetrain and quality Shimano brakes, without going top of the range. It is aimed at riders who head out once or twice a week on varied trails.

The LVR workshop view

Adjustable suspension ratio, the frame's trump card. This frame offers an adjustment that is rare at this price point: an adjustable suspension ratio, which changes the way the shock firms up at the end of its stroke. More progressive, it resists landings better; more linear, it makes fuller use of its 120 mm over loose rocks. On the FS 5, which gets a long-travel fork from size M, this setting helps balance the front and rear.

	Alpha Platinum (Powerfly+ FS)	Alpha NEXT Platinum (Fuel+ EX 8)	OCLV Mountain (Rail+ 9.7 / 9.8)
Level	Adjustable e-MTB aluminium	High-end mountain bike aluminium	OCLV Mountain carbon
Construction	Adjustable suspension ratio and geometry	Thinner tubes	Impact-oriented carbon moulding
Reference bike	Powerfly+ FS 5, 24.58 kg (M)	Fuel+ EX 8	Rail+ 9.7, 23.73 kg (M)
What it means	A frame you adapt to your terrain	Weight saving, more discreet motor	850 g lighter than this FS 5

Put simply: the FS 5 is the missing middle step between the 10-speed FS 4 and the FS 6. It moves up to 12 speeds and 4-piston Shimano brakes, and comes down to 24.58 kg in M, 920 g less than the FS 4 800 Wh.

The 12-speed XT 10-51 cassette offers closer gaps than the 10 speeds of the FS 4: you find the right cadence more easily, which makes the assist more efficient. The shorter 160 mm FSA cranks reduce pedal strikes on rocks in technical sections.

The four-piston Shimano MT620 brakes on 203 mm rotors offer welcome power and consistency on long descents. The Bosch assist, as European regulations require, cuts out at 25 km/h with 250 W nominal, and can be updated with the Bosch eBike Flow app.

Which Powerfly+ FS should you choose?

Model	Motor / battery	Rear / front travel	Drivetrain	Weight (M)
Powerfly+ FS 4 800 Wh	Bosch CX / 800 Wh	120 / 130 mm	Shimano CUES 10-speed	25.50 kg
Powerfly+ FS 5	Bosch CX / 800 Wh	120 / 160 mm	Shimano Deore/XT 12-speed	24.58 kg
Powerfly+ FS 6 (Fox 36)	Bosch CX / 800 Wh	120 / 140 mm	SRAM Eagle 70 12-speed	25.08 kg
Rail+ 5	Bosch CX / 800 Wh	160 / 160 mm	Shimano Deore 12-speed	24.78 kg

Our take: at 24.58 kg in M, the FS 5 weighs 920 g less than the FS 4 800 Wh, with 12 speeds and 4-piston Shimano brakes. The FS 6 with Fox 36 weighs 500 g more (25.08 kg) with Fox suspension.

LVR sizing advice

A quirk of the FS 5: size S gets a 130 mm Psylo and 27.5-inch wheels, sizes M to XL a 160 mm Psylo with 29-inch wheels. If you are between two sizes, bear this change of fork in mind; we explain it in store.

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	150	170	170
Wheels (in)	27.5	29	29	29
Fork (mm)	130	160	160	160
