Trek Fuel EXe 8 XT

Fuel EXe 8 is a trail-ready aluminum electric mountain bike that quietly assists you on the climbs so you've got all the power you need on descents. Like its carbon counterpart, it looks and handles like a traditional trail bike, but with the added support of a tiny-but-mighty harmonic pin ring drive system with sleek top-tube display unit and compact remote. It comes ready to rip with upgraded parts where they matter most, like a FOX suspension package, wide Bontrager Line Comp Tubeless Ready wheels, and a Shimano XT 12-speed drivetrain.

• You get all the tech of our top-end light e-MTB without a price tag that makes you say ouch
• Its upgraded FOX suspension package smooths the trail while 12-speed Shimano XT drivetrain shifts clean under load
• Its tiny but mighty TQ motor is tuned for the trail, keeping things quiet so you can stay in the moment, and ramps up power with you for a natural ride feel
• The integrated display, charging port, and controls are simple to use, sleek, and intuitive
• You can tweak your geometry with Mino Link, or add an adjustable angle headset to take even more control

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.

Slack or steep, the choice is yours

Install angle adjust headset cups (sold separately) to tweak the head tube angle a degree steeper or slacker to your liking — all without impacting your bottom bracket height.
