Who is it for?

For the mountain biker who wants to progress on descents and expects a hardtail e-MTB to genuinely adapt to their build. It is aimed at average-height riders as much as tall ones, each benefiting from a suitable saddle drop.

The LVR workshop view

Alpha Platinum aluminium, shared frame, rethought build. This Powerfly+ 6 keeps the 5th-generation Alpha Platinum aluminium frame, with its RIB 2.0 system that holds the battery in place even when you unlock it. The changes concern the wheels, dropper post, stem and chainset.

	Alpha Platinum (Powerfly+)	Alpha Gold (Marlin+)	OCLV Mountain carbon (Rail+ 9.7 / 9.8)
Level	Top-level Trek alloy	Alloy of the lightweight e-MTB	Trek off-road carbon
Construction	Battery secured by RIB 2.0	Compact 400 Wh battery	OCLV Mountain
Reference bike	Powerfly+ 6, 24.10 kg (M)	Marlin+ 8, 21.89 kg (M)	Rail+ 9.7 / 9.8
What it means	Secure battery, durable frame	Lighter, less energy	Lighter, full suspension

Put simply: at 24.10 kg in M, this Powerfly+ 6 keeps the big battery and RockShox fork of the Line Dropper version, but adopts 23 mm Kovee rims, Gunnison Elite tyres and a TranzX dropper whose travel increases with the size.

A dropper that is too long prevents you from setting the saddle low enough; too short and it doesn't clear enough room on descents. By grading the travel by size, Trek avoids this compromise: a rider on an M gets 150 mm, a tall rider on an L or XL 170 mm. When we hand the bike over, we check that your saddle height falls within the adjustment range.

The 50 mm, 0-degree Bontrager Rhythm Comp stem and 780 mm bar give a fairly low position and good control on descents. The Bosch CX motor remains subject to the European rule: 250 W rated, assist cut at 25 km/h.

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 (TranzX post, Kovee rims)	Bosch CX / 800 Wh	120 mm fork (100 in S)	Shimano 12-speed	24.10 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 (SRAM Eagle 70)	Bosch CX / PowerTube	Fox 120 mm (100 in S)	SRAM Eagle 70 12-speed	23.08 kg

Our take: with the same battery and fork, this TranzX Powerfly+ 6 weighs 24.10 kg in M, 300 g less than the Line Dropper version. The Powerfly+ 8 Eagle 70 moves up to a Fox fork for 23.08 kg.

LVR sizing advice

The TranzX post changes travel with each size: 100 mm in S, 150 mm in M, 170 mm in L and XL. If you are between sizes, the larger one gives more saddle drop and stability, the smaller one makes it easier to put a foot down.

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
Wheels (in)	27.5	29	29	29
Dropper post (mm)	100	150	170	170
