The LVR workshop view

Alpha Platinum aluminium, at the top of the hardtail range. The Powerfly+ 8 keeps the frame shared by all 5th-generation Powerfly+ models and puts everything into the spec. This Alpha Platinum alloy, one of Trek's most advanced aluminiums, takes an 800 Wh battery and 2.60 inch tyres here without any change to the geometry.

	Alpha Platinum (Powerfly+)	Alpha Gold (Marlin+)	OCLV Mountain carbon (Rail+ 9.7 / 9.8)
Level	Premium Trek aluminium	Marlin+ aluminium	OCLV Mountain carbon
Construction	Shared frame, high-end build	Slimmer frame, 400 Wh battery	Moulded under pressure and heat
Reference bike	Powerfly+ 8, 23.68 kg (M)	Marlin+ 8, 21.89 kg (M)	Rail+ 9.7 / 9.8
What it means	The budget goes into the fork and wheels	Lighter, less power	Weight saving on full suspension

Put simply: this Powerfly+ 8 is the best-equipped electric hardtail in this series, with a Fox fork, a Kiox 300 display and 2.60 inch tyres, for 23.68 kg in M. It is only available here in sizes S and L.

The Fox AWL Rail, with its Rail 2.0 damping, 15 mm Kabolt axle and 180 mm Direct Mount brake mount, gives this hardtail a fork that is a notch above. It keeps the front wheel well under control on the loose stones of the garrigue, where a simpler fork would tend to bounce.

The Kiox 300 display shows speed, battery level, mode and ride data, and connects to the Bosch eBike Flow app for updates. The motor complies with the European e-bike rule: 250 W rated and assist cut off above 25 km/h.

Which Powerfly+ should you choose?

Model	Motor / battery	Suspension (M)	Drivetrain	Weight (M)
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+ 8 (SRAM Eagle 70)	Bosch CX / PowerTube	Fox 120 mm (100 in S)	SRAM Eagle 70 12-speed	23.08 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: compared with the Powerfly+ 6 (24.40 kg), this Powerfly+ 8 weighs 23.68 kg in M and gains the Fox fork and Kiox display. The SRAM Eagle 70 version drops to 23.08 kg with narrower tyres.
