The Trek Powerfly+ 6 Gen 5 moves up a level from the Powerfly+ 4: a 170 mm Bontrager Line Dropper post from size M, a 12-speed Shimano XT derailleur and 4-piston Shimano brakes on 203 mm rotors. A Bosch Performance Line CX motor and 800 Wh battery, for 24.40 kg in size M according to Trek. The Lunar Silver/Mercury finish pairs a lunar silver with a mercury grey.

Who is it for?

For the mountain biker who wants to go beyond tracks and take on real trails, with steep, technical sections on the way down. It is aimed at anyone torn between this and a full-suspension bike who prefers the simplicity and low maintenance of a hardtail.

The LVR workshop view

Alpha Platinum aluminium, built for the big battery. An e-MTB frame has to withstand the motor's torque and the weight of an 800 Wh battery without flexing. Trek entrusts this job to Alpha Platinum, one of its best alloys, with a down tube large enough to swallow the PowerTube and a skid plate that protects the motor from stones.

	Alpha Platinum (Powerfly+)	Alpha Gold (Marlin+)	OCLV Mountain carbon (Rail+ 9.7 / 9.8)
Level	Trek high-end alloy	Alloy of the lightweight e-MTB	High-end mountain bike carbon
Construction	Oversized down tube for 800 Wh	Compact 400 Wh battery	OCLV compaction, reinforced lay-up
Reference bike	Powerfly+ 6, 24.40 kg (M)	Marlin+ 8, 21.89 kg (M)	Rail+ 9.7 / 9.8
What it means	Big battery, hardtail frame	Less battery, lighter weight	Full suspension, different budget

Put simply: this Powerfly+ 6 adds three things to the Powerfly+ 4 that matter on the trail: an 800 Wh battery, a 12-speed drivetrain with an XT derailleur and a dropper post. It weighs 24.40 kg in M.

The dropper post changes the way you ride: with one press of the lever on the bar, the saddle drops by 170 mm and frees up room to shift your hips back on the slopes of the Caroux. It comes back up on its own for the next climb. On a hardtail e-MTB, it is the component that makes technical descents accessible.

The four-piston Shimano brakes, with MT4100 levers and MT420 calipers, bite on 203 mm rotors front and rear: on a bike of more than 24 kg, that braking surface prevents overheating on the long descents towards the Orb. An annual bleed keeps them consistent.

Which Powerfly+ should you choose?

Model	Motor / battery	Suspension (M)	Drivetrain	Weight (M)
Powerfly+ 4 800 Wh (XCM fork)	Bosch CX / 800 Wh	120 mm fork	Shimano CUES 10-speed	24.90 kg
Powerfly+ 6 (Line Dropper post)	Bosch CX / 800 Wh	120 mm fork (100 in S)	Shimano XT / Deore 12-speed	24.40 kg
Powerfly+ 8 (Shimano XT / SLX)	Bosch CX / 800 Wh	Fox 120 mm (100 in S)	Shimano XT / SLX 12-speed	23.68 kg
Powerfly+ FS 4 800 (full-suspension)	Bosch CX / 800 Wh	130 mm front / 120 mm rear	Shimano CUES 10-speed	25.50 kg

Our take: the Powerfly+ 6 brings 800 Wh, a 170 mm dropper and 12 speeds for 24.40 kg in M. The Powerfly+ 8 moves up to a Fox fork and a Kiox 300 display for 23.68 kg; the Powerfly+ FS 4 800 adds 120 mm of rear suspension.

LVR sizing advice

If you are between sizes, go for the smaller one if you mainly want agility on singletrack, the larger one for stability on long tracks. The dropper goes from 100 mm in S to 170 mm from M upwards.

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
Fork (mm)	100	120	120	120
Dropper post (mm)	100	170	170	170

Your questions

Why a dropper post?	To lower the saddle for descents without stopping, and gain confidence on steep slopes.
Are the 203 mm rotors useful?	Yes, they dissipate heat better on a heavy bike on a long descent.
Hardtail or full suspension?	A hardtail is simpler and lighter; a full-suspension bike is more comfortable on rough terrain.
Does the silver grey show the dirt?	It hides the pale dust of the tracks around Béziers well.

The LVR Cycles verdict

A hardtail Powerfly+ ready for real trails, thanks to its dropper post and big brakes. Its lunar silver and mercury grey stay elegant and don't show the dirt much.

Pros
+ 170 mm dropper post
+ 4-piston brakes on 203 mm rotors
+ 800 Wh battery

Cons
- No rear suspension
- Purion controller without a large display
