Fuel EXe 9.8 XT takes an evolved approach to e-mountain bikes with a revolutionary motor that packs space-age technology into a tiny but mighty package. It's built on an OCLV Mountain Carbon 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 carbon wheels, Shimano's clean-shifting and ultra-reliable XT drivetrain, and the silky-smooth performance of a RockShox Lyrik Select+ fork and SuperDeluxe Select+ rear suspension.

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 360Wh battery and TQ harmonic pin ring transmission with a smart charging port, integrated LED display, and discreet handlebar remote. Plus, a 150mm RockShox Lyrik Select+ fork with DebonAir spring and Charger 2.1 RC damper, and 140mm RockShox Super Deluxe Select+ rear suspension. And don't forget the trusted performance of Shimano's clean-shifting XT drivetrain.

The final word
Fuel EXe 9.8 is a refined trail bike with just the right amount of power for scorching climbs before turning around to rally through 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.

TQ-HPR50 – small, quiet, mighty
The TQ-HPR50 motor is super-efficient with an amazing power-to-weight ratio. Most motors use gears and belts that take up space and can make noise or break. The TQ-HPR50 uses a harmonic pin-ring drive transmission that’s small, ultra-quiet and unbelievably natural-feeling.

Range Extender
Give yourself 40% more range with an optional 160wh external battery. It fits in a standard bottle cage and doesn’t require any complicated wiring or special mounts.

Connect, customize, calculate
The Trek Central app seamlessly connects with your bike for custom motor tuning, activity tracking, and more ways to analyze and personalize your ride. You even get navigation features and real-time range calculations.

Removable battery
The 360 Wh battery gives you power for 2-5 hours. It’s concealed in the downtube, but it’s still easy to remove for more convenient charging.

Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

Shimano XT
Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high-performance workhorse you can count on.
