Who is it for?

For the mountain biker discovering e-MTBs who wants a bike that can go anywhere from day one, from wide fire roads to mountain trails. It also suits anyone riding with fitter friends who wants to keep up on long climbs.

The LVR workshop view

Alpha Platinum aluminium, the solid foundation of the Rail+. Trek reserves Alpha Platinum for its most demanding mountain bikes: shaped tubes and carefully finished welds, for a frame that takes repeated knocks. On the Rail+ 5, it gets the same layout as the carbon versions, with a removable RIB 2.0 battery, Motor Armor protection under the motor and adjustable geometry. The extra weight is limited to 1.05 kg compared with the carbon Rail+ 9.7 XT, for a much gentler budget.

	Carbon Rail+ (9.7 / 9.8)	Aluminium Rail+ (5 / 8)	Carbon Slash+ (TQ)
Frame	OCLV Mountain main frame	Alpha Platinum	OCLV Mountain
Drive system	Bosch CX, PowerTube 800 Wh	Bosch CX, PowerTube 800 Wh	TQ HPR60, 580 Wh
Weight (M)	23.73 to 24.18 kg	24.78 to 25.08 kg	21.58 to 21.83 kg
What it means	Lighter chassis, same motor	Gentler budget, robust frame	Gentler assist, livelier bike

Put simply: the Rail+ 5 gives you the Bosch CX motor and 800 Wh battery found across the range, with a simple, reliable Deore and RockShox build.

The Bosch CX delivers 85 Nm as standard, adjustable up to 100 Nm in the eBike Flow app, and its eMTB mode meters the assist according to how hard you press on the pedals. The assist stops at 25 km/h, the European limit for a 250 W rated motor. On the rocky tracks climbing towards the Espinouse plateau, that torque turns a climb you endure into one you control.

The 800 Wh battery slides out of the down tube thanks to the RIB 2.0 system, handy for charging it indoors in winter. The RockShox Psylo Gold and Deluxe Select+ pairing offers 160 mm that is easy to set up, and the four-piston Shimano brakes on 203 mm rotors go the distance on long descents.

Which Rail+ should you choose?

Model	Motor / battery	Rear / front travel	Drivetrain	Weight (M)
Rail+ 5	Bosch CX / 800 Wh	160 / 160 mm	Shimano Deore 12-speed	24.78 kg
Rail+ 8	Bosch CX / 800 Wh	160 / 160 mm	Shimano XT / Deore 12-speed	25.08 kg
Rail+ 9.7 XT	Bosch CX / 800 Wh	160 / 160 mm	Shimano XT / SLX 12-speed	23.73 kg
Rail+ 9.8 GX AXS	Bosch CX / 800 Wh	160 / 160 mm	Wireless SRAM GX AXS	24.18 kg

Our take: at 24.78 kg in M, the Rail+ 5 weighs 1.05 kg more than the carbon Rail+ 9.7 XT (23.73 kg) with the same motor and battery. It is even 300 g lighter than the aluminium Rail+ 8 (25.08 kg), which has better suspension.

LVR sizing advice

If you are between sizes, go for the smaller one if you are new to e-MTBs: a bike of nearly 25 kg is easier to place on the trail when it is shorter. The dropper goes from 100 mm in S to 170 mm from M upwards, and size S rolls on 27.5 inch wheels front and rear.

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
Dropper post (mm)	100	170	170	170
Front / rear wheels (in)	27.5 / 27.5	29 / 27.5	29 / 27.5	29 / 27.5
