Who is it for?

The LVR workshop view

Alpha Platinum aluminium, the foundation of the Powerfly+. Trek groups its alloys under the Alpha name, and Platinum is one of the top grades in the family, just below the Alpha NEXT Platinum of the Fuel models. On this Powerfly+ 4, it forms a hardtail frame that houses the battery in the down tube, protects the motor under a Motor Armor skid plate and routes the cables internally.

	Alpha Platinum (Powerfly+)	Alpha Gold (Marlin+)	OCLV Mountain carbon (Rail+ 9.7 / 9.8)
Level	Top grade of Trek aluminium	Aluminium of the entry-level e-MTB	Trek mountain bike carbon
Construction	Shaped tubes, battery housed in the down tube	Shaped tubes, compact battery	Layers compacted under heat, impact-resistant lay-up
Reference bike	Powerfly+ 4, 23.10 kg (M)	Marlin+ 8, 21.89 kg (M)	Rail+ 9.7 / 9.8 full-suspension
What it means	Tough, takes a big battery	Lighter, less powerful motor	Reserved for high-end full-suspension bikes

Put simply: the Powerfly+ 4 gives you the most powerful Bosch motor in the hardtail range with a 600 Wh battery and deliberately simple mechanics. It is the lightest version of the Powerfly+ 4, at 23.10 kg in M.

The Shimano CUES drivetrain is based on Linkglide technology: thicker cassette teeth and a dedicated chain, designed to last longer than conventional mountain bike drivetrains under the torque of an electric motor. With a 36-tooth chainring and an 11-48 cassette, you keep an easy gear for the ramps of the garrigue and enough top end to ride fast on tracks.

The 2.40 inch Bontrager XT3 Comp tyres offer plenty of air volume to absorb stones, and the SR Suntour XCR 34 air-sprung fork can be set for your weight with a simple shock pump. Its hydraulic lockout firms up the front end on the tarmac links between two trails.

Which Powerfly+ should you choose?

Model	Motor / battery	Suspension (M)	Drivetrain	Weight (M)
Marlin+ 8	Bosch Active Line Plus / 400 Wh	120 mm fork	Shimano Deore 12-speed	21.89 kg
Powerfly+ 4	Bosch CX / 600 Wh	120 mm fork (100 in S)	Shimano CUES 10-speed	23.10 kg
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

Our take: the Powerfly+ 4 is the lightest of the Powerfly+ 4 models (23.10 kg in M), with its 600 Wh battery. If you string together big rides, the 800 Wh adds 200 Wh for 1.80 kg more; if you want an even more natural-feeling bike, the Marlin+ 8 drops to 21.89 kg.

LVR sizing advice

If you are between sizes, the smaller one makes the bike easier to handle when stationary and in hairpins, the larger one more settled on fast tracks. Size S rolls on 27.5 inch wheels with a 100 mm fork; from M to XL, 29 inch wheels and 120 mm.

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
Seatpost (mm)	330	360	400	400

Your questions

Is 600 Wh enough?	For rides of a few hours, yes; real-world range depends on climbing, mode and your weight.
What maintenance does CUES need?	Regular cleaning and lubrication; the Linkglide chain wears more slowly than a conventional chain.
Does the battery come out?	Yes, it slides out of the down tube so you can charge it at home.
Is the fluorescent green discreet?	No, it is a high-visibility green that stands out clearly against the matt grey.

The LVR Cycles verdict

The simplest Trek electric mountain bike to get started: Bosch CX motor, Alpha Platinum frame and a drivetrain built to last. Its matt grey with fluorescent green highlights makes it visible from afar on trails and in town alike.

Pros
+ Bosch CX motor from the entry-level model
+ Very durable CUES drivetrain
+ High-visibility colourway

Cons
- Rigid seatpost, not a dropper
- 600 Wh for very long rides
