Who is it for?

For the medium-to-tall rider, with an inseam of 84 to 89 cm, who wants an enduro e-MTB ready for serious descents straight away. It will appeal to anyone who insists on a saddle that drops right out of the way on steep slopes and a wide cockpit to hold the bike through the rocks.

The LVR workshop view

OCLV carbon, Trek's signature. Thirty years of know-how sum up OCLV: a stack of pre-impregnated fibres, cured and pressed in the mould until not a single air bubble remains. On an electric enduro bike, the OCLV Mountain version really comes into its own: its lay-up is designed to withstand flying stones and landings, with a heavier load on board than a non-assisted mountain bike. On the Fuel+ LX, it also houses a 580 Wh TQ battery that comes out without any complicated tools, and Trek covers it with a lifetime warranty.

	OCLV Mountain (Fuel+ 9.7 to 9.9)	Alpha NEXT Platinum (Fuel+ EX 8)	Road OCLV (Madone, Domane)
Level	Trek's off-road carbon	Most advanced mountain bike aluminium	Road bike carbon
Construction	Lay-up reinforced against impacts	Hydroformed tubes	Lay-up focused on lightness
Reference bike	Fuel+ EX 9.8 XT: 20.10 kg (M)	Fuel+ EX 8: 21.08 kg (M)	not applicable to mountain bikes
What it means	0.98 kg lighter for the same travel	Tough, a little heavier	Not designed for impacts

Put simply: this Fox-suspended Fuel+ LX 9.8 Eagle 90 is the only Fuel+ LX for which Trek publishes a weight, 20.88 kg in size M. That is 780 g more than the Fuel+ EX 9.8 XT (20.10 kg), in exchange for 15 mm of extra travel at the rear, 20 mm at the front and a coil shock.

In size L, the Bontrager Line Dropper post offers 200 mm of travel: the saddle disappears from under you as soon as the slope steepens, leaving plenty of room to move your hips. Paired with the 800 mm Race Face ERA carbon bar, it gives an open, reassuring riding position on the steps of the Espinouse.

At the front, the Maxxis Assegai in MaxxGrip compound bites hard in dusty corners, while the Minion DHR II MaxxTerra at the rear brakes in a straight line and wears more slowly. The TQ assist, capped at 25 km/h and limited to 250 W rated as e-bike regulations require, lets you climb back to the top without arriving exhausted.

Which Fuel+ should you choose?

Model	Motor / battery	Rear / front travel	Drivetrain	Weight (M)
Fuel+ EX 9.8 XT	TQ HPR60 / 580 Wh	145 / 150 mm	Shimano XT	20.10 kg
Fuel+ MX 9.8 XT Di2	TQ HPR60 / 580 Wh	150 / 160 mm	Shimano XT Di2	19.79 kg
Fuel+ LX 9.8 Eagle 90 (Fox)	TQ HPR60 / 580 Wh	160 / 170 mm	SRAM Eagle 90	20.88 kg
Slash+ 9.9 (mixed 29 / 27.5)	TQ HPR60 / 580 Wh	170 mm fork	SRAM X0 AXS	21.83 kg

Our take: this colourway in L shares everything with the navy blue version, including the 20.88 kg in M. Compared with the Fuel+ EX 9.8 XT (20.10 kg), you gain 15 mm of rear travel and 20 mm at the front, plus an enduro-oriented Assegai front tyre.

Your questions

What build is it for?	Trek designs size L for riders from 177 to 188 cm with an 84 to 89 cm inseam.
Isn't a 200 mm dropper too much?	Not for these measurements; we check the insertion depth when we hand the bike over.
Can the bar be cut down?	Yes, the 800 mm Race Face ERA carbon bar can be cut down in the workshop, after measuring.
Is the grey uniform?	No, a light grey marbling runs through the smoky carbon grey.

The LVR Cycles verdict

A ready-to-ride Fuel+ LX for riders from 1.77 m to 1.88 m, with a saddle that drops by 200 mm and a wide carbon cockpit. The marbled smoky grey gives it a technical, refined look.

Pros
+ 200 mm dropper post
+ 800 mm ERA carbon handlebar
+ Highly distinctive marbled grey

Cons
- Only one size in this colourway
- Aluminium wheels as standard
