Trek Fuel+ MX 9.8 XT Di2 Carbon Smoke: an all-mountain e-MTB that handles like a mountain bike

Quoted at 19.79 kg in size M by Trek, the Trek Fuel+ MX 9.8 XT Di2 is an easy-handling all-mountain electric mountain bike, thanks to its compact TQ HPR60 motor and 580 Wh battery. OCLV Mountain carbon frame, Fox Factory 150 / 160 mm and wireless Shimano XT Di2 complete the package. The Carbon Smoke/Lithium Grey Marble dresses it in a smoky anthracite grey shot through with lithium grey marbling.

Who is it for?

For the mountain biker who loads their bike onto a bike rack, carries it up stairs or pushes it on sections that are too steep, and does not want to wrestle with a bulky e-MTB every time. It is also aimed at lighter riders, for whom a heavy bike quickly becomes hard to place in corners.

The LVR workshop view

OCLV carbon, Trek's signature. Behind the OCLV acronym lies a moulding method Trek has used for more than thirty years: the carbon layers are pressed at high temperature until the air bubbles that weaken a composite are eliminated. The Mountain version of this carbon is calibrated for the impacts of mountain biking rather than for saving grams. It is what allows the Fuel+ MX 9.8 XT Di2 to carry a motor, a 580 Wh battery and a 160 mm fork for 19.79 kg in size M, with the Trek lifetime warranty on the frame.

	Fuel+ (TQ HPR60)	Fuel EXe (TQ HPR50)	Rail+ (Bosch CX)
Motor	TQ HPR60, 60 Nm	TQ HPR50, 50 Nm	Bosch Performance Line CX
Battery capacity	580 Wh	360 Wh	800 Wh
Published weight (M)	19.79 kg	19.33 kg (EXe 9.7)	23.73 kg (Rail+ 9.7)
Who it is for	Riders who want an agile bike and a real reserve	Mountain bikers who put a natural feel first	Big days out and very steep slopes

Put simply: the Fuel+ MX 9.8 XT Di2 is the only Fuel+ MX for which Trek publishes a weight, 19.79 kg in size M, which is 310 g less than the Fuel+ EX 9.8 XT quoted at 20.10 kg. It combines Fox Factory suspension, a Shimano wireless drivetrain and a 580 Wh battery on the range's all-mountain frame.

A lighter bike is felt above all in changes of direction and jumps: the Fuel+ MX lifts, places and manuals more easily than an e-MTB with a big battery. The frame also includes transport protection and a down tube guard against flying stones.

The 580 Wh battery is a deliberate compromise: enough for great mountain loops if you manage the assist, for less weight than an 800 Wh battery. The motor's help cuts out at 25 km/h, with 250 W nominal, in line with the European e-bike rule.

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	Mechanical Shimano XT	20.10 kg
Fuel+ MX 9.8 XT	TQ HPR60, 580 Wh	150 / 160 mm	Mechanical Shimano XT	not disclosed
Fuel+ MX 9.8 XT Di2	TQ HPR60, 580 Wh	150 / 160 mm	Wireless Shimano XT Di2	19.79 kg
Fuel+ MX 9.9 X0 AXS	TQ HPR60, 580 Wh	150 / 170 mm	Wireless SRAM X0 Eagle AXS	not disclosed

Our take: 19.79 kg in M for the Fuel+ MX 9.8 XT Di2, against 23.73 kg for the Rail+ 9.7 and its 800 Wh Bosch battery: nearly 4 kg of difference, in exchange for a smaller energy reserve. The Fuel+ EX 9.8 XT, with less travel, is quoted at 20.10 kg.

LVR sizing advice

If you are hesitating between two sizes, the shorter one makes changes of direction in the woods easier, the longer one inspires confidence on fast, rough descents. Dropper travel follows frame size, from 150 to 200 mm.

Rider height (cm)	155-165	165-177	177-188	188-195	195-203

Your questions

Can it go on a bike rack?	Yes; removing the battery makes the bike even lighter for loading.
Is 580 Wh enough?	For all-mountain riding, yes, if you manage the modes; we advise you based on your routes.
What is the transport protection for?	It limits rubbing on the carbon frame when travelling.
Is the grey light or dark?	A smoky anthracite grey, lightened by paler lithium grey veins.

The LVR Cycles verdict

An all-mountain e-MTB that stays light and playful, for those who often handle their bike and want to keep the riding pleasure of a mountain bike. The marbled smoky grey gives it a very successful technical look.

Pros
+ 19.79 kg in M, a bike that is easy to place
+ Removable battery and transport protection
+ Very elegant marbled grey

Cons
- Smaller energy reserve than a Bosch 800 Wh
- Aluminium wheels and handlebar
