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

Trek Fuel+ LX 9.8 XT Di2 Lichen Green: an assisted enduro bike controlled from your phone

A TQ colour LED display with Bluetooth on the bar, a wireless Shimano XT Di2 derailleur at the rear: the Trek Fuel+ LX 9.8 XT Di2 presents itself as a highly connected assisted enduro bike. Under the OCLV Mountain carbon work a TQ HPR60 with 60 Nm and 350 W peak and a 580 Wh battery, with 160 / 170 mm of Fox Factory suspension. Trek publishes nothing about the weight, which is not given for this version; benchmark, Fuel+ LX 9.8 Eagle 90 at 20.88 kg in size M. The Lichen Green/Keswick Green Splatter throws dark green splashes over a soft lichen green.

Technical specifications

Who is it for?

For the mountain biker who likes to track their data and customise their bike from their smartphone: assist levels, state of charge, control settings. It will suit anyone who rides big day loops and wants to know their battery status at all times.

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.

The TQ display integrated into the cockpit shows the charge and selected mode; its Bluetooth connection links the bike to the Trek Central / TQ app, which lets you adjust the motor's response. We carry out software updates every time the bike comes into the workshop, along with a check of the Di2 derailleur.

On a long ride in the Espinouse, managing your energy well makes the difference: a gentle level on rolling tracks, maximum assist saved for the ramps. The TQ complies with the European framework for e-bikes, 250 W nominal power and assist cutting out at 25 km/h; the electronic drivetrain, meanwhile, keeps up with every change of pace.

Which Fuel+ should you choose?

Our take: with its connected display and Di2, this Fuel+ LX is the most electronic of the 9.8 models. The 9.9 X0 AXS switches to SRAM wireless and Line Pro 30 wheels; the Fuel+ MX 9.8 XT Di2, at 19.79 kg in M, offers 150 / 160 mm.
