Trek Fuel EXe 9.8 (2025)

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. What you put on your bike matters to you, so you love the Shimano XT drivetrain 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 an easily removable 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 2.1 RC damper, and 140 mm RockShox Super Deluxe Select+ rear suspension. And don't forget the trusted performance of Shimano's clean shifting XT drivetrain.

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 Shimano XT shifting that keeps your cockpit minimalist. Finally, carbon wheels and an upgraded RockShox suspension package keeps you floating on the trail even when the conditions get hairy.
