Carbon full-suspension electric mountain bike Trek Fuel+ LX 9.8 XT Di2: TQ HPR60 580 Wh, Di2, 160/170 mm

Trek Fuel+ LX 9.8 XT Di2 Navy Smoke: precise shifting under motor power

The Trek Fuel+ LX 9.8 XT Di2 shifts gears without a cable thanks to the Shimano XT Di2 M8260 derailleur, on an OCLV Mountain carbon frame fitted with a TQ HPR60 and a 580 Wh battery. Its Fox Factory suspension offers 170 mm of travel up front and 160 mm at the rear. Weight: not published by Trek for this version; benchmark, the Fuel+ LX 9.8 Eagle 90 at 20.88 kg in size M. Gloss Navy Smoke/Matte Trek Black finish: a deep, lustrous navy, cut through with satin black sections.

Technical specifications

Who is it for?

For the rider who demands crisp gear changes, even mid-climb when the motor is pulling on the chain, and a cockpit free of derailleur housing. It will appeal to anyone who often rides in dust or mud, where a cable always ends up losing precision.

The LVR workshop view

OCLV carbon, Trek's signature. Behind the OCLV acronym lies a moulding process Trek has been perfecting for more than thirty years: heat and pressure for carbon with no porosity. For mountain biking, the Mountain variant is engineered to withstand rock strikes and crashes, which matters on an assisted bike that goes faster and for longer through rock gardens. The Fuel+ LX adds guided internal routing that neatly tidies away the housing and motor wiring, plus the Trek lifetime warranty.

Put simply: compared with the 9.8 XT, only one part changes: the wireless XT Di2 M8260 derailleur replaces the cable-operated model; the Fox 38, DHX2, XT brakes and wheels are shared. No official weight for this version; the benchmark remains the Fuel+ LX 9.8 Eagle 90, 20.88 kg in M.

An electronic derailleur does not get gummed up like a cable: day-one precision stays intact after months of dry tracks and wet sections. On the trails of the Montagne Noire, where you often change gear between accelerations, this consistency is felt with every press of the shifter.

With the TQ assist, 250 W nominal and cutting out at the legal 25 km/h, the chain is under more tension than on a non-assisted mountain bike. Di2 moves the chain crisply and repeatably, which avoids clunks and spares the cassette and chainring on steep ramps.

Which Fuel+ should you choose?

Our take: this model and the Fuel+ LX 9.8 XT differ only in the derailleur, electronic here, cable-operated on the XT. If you also want higher-end wheels and dropper, the 9.9 X0 AXS adds Line Pro 30 wheels, Maven Silver brakes and a Fox Transfer Neo.
