Carbon full-suspension electric mountain bike Trek Fuel+ LX 9.8 XT: TQ HPR60 580 Wh, Fox 38, 160/170 mm

Trek Fuel+ LX 9.8 XT Navy Smoke: Shimano XT and Fox for assisted enduro

The Trek Fuel+ LX 9.8 XT pairs a 12-speed mechanical Shimano XT drivetrain and four-piston XT M8220 brakes with an OCLV Mountain carbon frame powered by TQ (HPR60, 580 Wh). Its Fox Factory 38 and coil-sprung DHX2 suspension offer 170 mm up front and 160 mm at the rear. Trek gives no figure: weight not published by Trek for this version, with the Fuel+ LX 9.8 Eagle 90 at 20.88 kg in size M as a benchmark. The Gloss Navy Smoke/Matte Trek Black combines glossy smoky navy with matt black.

Technical specifications

Who is it for?

For the mountain biker loyal to Shimano, used to the feel of XT brakes and the precision of its derailleurs, who is moving to an enduro e-MTB without changing their reference points. It is also aimed at anyone who likes a machine that is simple to live with, with no derailleur battery to keep an eye on.

The LVR workshop view

OCLV carbon, Trek's signature. Trek builds its OCLV frames by layering fibre plies compacted under pressure, which eliminates air bubbles and gives a uniform material. For off-road use, the OCLV Mountain recipe reinforces the exposed areas; on the Fuel+, it also integrates the housing for a removable TQ battery and protection under the down tube. The result: an electric enduro frame with a reasonable weight, covered by the brand's lifetime warranty.

Put simply: the 9.8 XT combines Fox Factory suspension, with a coil shock at the rear, a mechanical Shimano XT 10-51 drivetrain and XT brakes on 200 mm rotors. Trek does not publish a weight for this version; the Fuel+ LX 9.8 Eagle 90, with the same frame and TQ motor, is quoted at 20.88 kg in M.

The XT M8220 brakes offer progressive bite and a lever with a consistent bite point; on 200 mm rotors, they handle the long descents down to the Orb valley without losing power. Their mineral oil is easy to bleed, something we recommend at the start of every season given the summer heat.

The XT 10-51 cassette and long-cage derailleur deliver crisp shifting even under motor load. The TQ HPR60, limited to 250 W nominal and cutting out at 25 km/h as the law requires, pushes without brutality, which spares the chain and makes traction easier to manage on steep climbs.

Which Fuel+ should you choose?

Our take: between this 9.8 XT and the 9.8 Eagle 90 with Fox suspension (20.88 kg in M), the frame, motor and suspension are identical; what changes is the brand of drivetrain and brakes. Compared with the Fuel+ EX 9.8 XT (20.10 kg), you gain 15 mm at the rear and 20 mm up front.
