The LVR workshop view

Alpha Platinum aluminium, equipped edition for smaller riders. Even in size S, this Powerfly+ gets the full Alpha Platinum frame: an 800 Wh battery housed in the down tube, internal cables and a motor skid plate. The frame mounts take the MIK-compatible rear rack and the kickstand, without clamps or adapters.

	Alpha Platinum (Powerfly+)	Alpha Gold (Marlin+)	OCLV Mountain carbon (Rail+ 9.7 / 9.8)
Level	Superior Trek aluminium	Marlin+ aluminium	Trek mountain bike carbon
Construction	Equipped frame, 800 Wh, size S	Light frame, 400 Wh	OCLV Mountain
Reference bike	Powerfly+ 4 Equipped 800 Wh (S)	Marlin+ 8, 21.89 kg (M)	Rail+ 9.7 / 9.8
What it means	Range and complete equipment	Lighter, kit it out yourself	No urban kit

Put simply: this is the most complete Powerfly+ for a rider from 155 to 165 cm who rides every day. Trek doesn't publish its weight; the XCM fork version, with the same equipped frame and battery, weighs 27.20 kg in M.

The 800 Wh battery spaces out charging for everyday use: depending on your journey, you won't necessarily need to charge every evening. The RIB 2.0 system lets you take it into the office while the frame stays in the bike store, and the remaining charge is shown on the Purion 200.

On an equipped bike, the LT4 Expert tyres with a reflective strip and the mudguards make the difference in winter. The Bosch CX motor, restricted to 25 km/h in Europe for 250 W rated, lets you ride in everyday clothes even on the hilly roads leading into Béziers.

Which Powerfly+ should you choose?

Model	Motor / battery	Suspension (M)	Drivetrain	Weight (M)
Powerfly+ 4 Equipped	Bosch CX / 600 Wh	120 mm fork (100 in S)	Shimano CUES 10-speed	25.70 kg
Powerfly+ 4 Equipped 800 Wh (XCR fork, size S)	Bosch CX / 800 Wh	100 mm fork (S)	Shimano CUES 10-speed	not disclosed
Powerfly+ 4 Equipped 800 Wh (XCM fork)	Bosch CX / 800 Wh	120 mm fork	Shimano CUES 10-speed	27.20 kg
Powerfly+ 4 800 Wh (XCM fork)	Bosch CX / 800 Wh	120 mm fork	Shimano CUES 10-speed	24.90 kg

Our take: in size S, this 800 Wh Equipped keeps the 100 mm XCR fork. The 600 Wh Equipped (25.70 kg in M) is lighter but has less range; the XCM fork version moves up to 120 mm.
