2025 Trek Fuel EXe 9.8 GX AXS T-Type - Dark Star
The Fuel EXe 9.8 GX AXS takes an evolved approach to e-mountain biking with a revolutionary motor that packs space-age technology in a tiny but mighty package. It's built on a carbon fibre chassis that's light, stiff and nimble for a lively and playful trail feel. And to keep a good thing going, it's topped off with the wireless shifting technology of a SRAM GX AXS transmission and the silky-smooth suspension of a RockShox Lyrik Select+ fork and SuperDeluxe Select+ rear suspension.

SPECS
It's right for you if...
You want a lively trail bike that feels like a traditional mountain bike in quick, techy terrain, but gives you a little boost in pedal power on the way back up. You want space-age technology everywhere from motor to group set, and upgraded suspension that keeps you floating on the trail. You don't want to lose out on the natural experience of mountain biking, and want a refined motor that quietly assists while you ride.
The tech you get
An OCLV Mountain Carbon frame equipped with a fully encased 360 Wh battery and TQ harmonic pin ring transmission with a smart charging port, integrated LED display and discreet handlebar remote. Plus, a 150 mm RockShox Lyrik Select+ fork with DebonAir spring and Charger 3.1 RC damper, and 140 mm RockShox Super Deluxe Select+ rear suspension. The cherry on top? SRAM's GX AXS transmission that keeps shifts crispy, even under load.
The final word
The Fuel EXe 9.8 is a refined trail bike with just the right amount of power for scorching climbs before turning around to rally though technical and flow trails alike. It's equipped with future-minded technology, like the space-approved TQ transmission and wireless SRAM GX AXS shifting that keeps your cockpit minimalist. Finally, an upgraded RockShox suspension package keeps you floating on the trail even when the conditions get hairy.
