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 SR Suntour XCR 34 fork uses an air spring: you set its firmness with a pump according to the rider's weight, so a light rider and a heavy rider alike can get the right sag. The 2CR damping and hydraulic lockout round things off for tarmac climbs.

A small size on 27.5 inch wheels lowers the centre of gravity and makes low-speed manoeuvres easier, which is invaluable when you are new to a bike of more than 20 kg. The larger sizes on 29 inch wheels roll more easily over the roots and steps on the trails of the Montagne Noire.

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 three Powerfly+ 4 colourways share the XCR fork and 600 Wh battery; only the black one changes tyres. If your budget allows, the Powerfly+ 6 adds a dropper post and 800 Wh for 24.10 kg.
