Who is it for?

For the mountain biker who often rides alone or in a small group, early in the morning or late in the day, and wants to be easily spotted by other trail users. It will also suit the rider looking for a tough e-MTB for mountain loops.

The LVR workshop view

Alpha Platinum aluminium, built for full power. The Rail+ 8 keeps the aluminium frame of the Rail+ 5 but steps up a notch on the parts that take the hits: a ZEB fork with 38 mm stanchions, wider Line Comp 30 rims and Brevard Pro XR tyres. The welded Alpha Platinum alloy, protected by Motor Armor, handles the 85 Nm of the Bosch CX and the impacts of the terrain without flinching.

	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+ 8 is the aluminium Rail+ equipped for enduro, with the same RockShox suspension as the carbon Rail+ 9.7 XT; it weighs 1.35 kg more than the latter in M.

The Bosch CX delivers 85 Nm out of the box, which the eBike Flow app lets you push to 100 Nm; its eMTB mode adapts the assist to the force you put through the pedals. On the steep ramps leading up to the ridges of the Montagne Noire, that torque keeps your momentum going. The assist remains capped at 25 km/h, the European rule for a 250 W rated motor.

The Line Dropper post ranges from 150 mm in S to 200 mm in L: the saddle drops right out of the way for descending. The RIB 2.0 system lets you take the 800 Wh battery out of the frame, useful for charging it in a heated room in winter rather than in a cold garage.

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 XT Di2	Bosch CX / 800 Wh	160 / 160 mm	Wireless Shimano XT Di2	23.98 kg

Our take: at 25.08 kg in M, this Rail+ 8 is 1.1 kg heavier than the carbon Rail+ 9.8 XT Di2 (23.98 kg); that is the price of an aluminium frame and a simpler spec, with an identical drive system.

LVR sizing advice

The dropper post grows with the frame: 150 mm in S, 170 mm in M, 200 mm above that. Size S rolls on two 27.5 inch wheels, easier to handle for a smaller rider; from M upwards, it runs a 29 front and 27.5 rear setup.

Size	S	M	L
Rider height (cm)	155-165	165-177	177-188
Inseam (cm)	74-78	79-83	84-89
Dropper post (mm)	150	170	200
Front / rear wheels (in)	27.5 / 27.5	29 / 27.5	29 / 27.5

Your questions

Can the motor torque be adjusted?	Yes, from 85 to 100 Nm in the Bosch eBike Flow app.
Where should the battery be charged in winter?	In a heated room; the removable RIB 2.0 battery comes out of the frame easily.
Which sizes for this colourway?	S, M and L, from 155 to 188 cm according to the Trek guide.
Does the fluorescent green fade?	It is a lacquered paint; a protective film preserves its brightness against rubbing.

The LVR Cycles verdict

A tough, powerful aluminium Rail+, made visible everywhere by its fluorescent green. A solid base for riding often in the mountains.

Pros
+ High-visibility green
+ Bosch CX adjustable up to 100 Nm
+ Dropper up to 200 mm in L

Cons
- 25.08 kg in size M
- No XL size in this colourway
