Who is it for?

For the mountain biker who heads out for the day, racks up long climbs and wants to keep some battery in hand until they get home. It will also suit anyone riding in a group with riders on non-assisted mountain bikes who wants to adjust the assist to stay with them.

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.

With 800 Wh, you can stay longer in the higher assist modes or stretch the ride out in eco mode. We don't give a range figure: it depends on climbing, weight, temperature and the mode you choose. A well-stored battery, at half charge and kept away from the cold in winter, retains its capacity for longer.

The 10-51 cassette offers a very wide spread between the smallest and largest sprockets: enough to keep a smooth cadence on the ramps of the Espinouse forestry fire tracks, where the motor works best, then ride fast on the flat. The assist stops at 25 km/h, as European regulations require, with a 250 W rated motor.

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: on big rides, the Powerfly+ 6 keeps 200 Wh in hand over the 600 Wh Powerfly+ 4. The Powerfly+ 8 keeps this battery and adds a Fox fork; the FS 4 800 offers the same energy with full 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

What range can I expect with 800 Wh?	It varies too much with terrain and mode to put a figure on it; we advise you based on your routes.
How should the battery be stored in winter?	At half charge, somewhere dry, at room temperature, and topped up from time to time.
What updates are there?	The Bosch system is updated via the eBike Flow app or in the workshop.
Is the orange bright?	Yes, it is a bold, sunny orange set against a dark black.

The LVR Cycles verdict

The Powerfly+ 6 for big days in the mountains, with its 800 Wh battery and 10-51 cassette. The sunny orange and deep black give it an energetic look.

Pros
+ 800 Wh battery that goes the distance

+ Bright, distinctive orange

Cons
- 24.40 kg in M
- Recon fork less adjustable than a Fox
