"Fuel EX is a beautifully balanced and capable trail bike. The rear suspension is beautiful; as close to ideal as any bike I've ridden. It's sensitive where you want it to be, firm and crisp where it should be. It feels deep and controls big hits very well, and there's a nice platform for pedaling, and to pump and pop off when you're playing."Read more
"Fuel EX has a few tricks that help it keep a level head when outside of its comfort zone, and to be a cloud on rails when it's in the zone. Everything about the Fuel EX, which was already good at pleasing everybody, is now even better at it."Read more
"Thanks to its burlier components, increased travel, and more aggressive geometry, it has become more of a shredder than ever! More performance, fun, and trail prowess."Read more
"In a world where most new full-suspension mountain bikes are amazing, Fuel EX stands apart as even more than that."Read more
Choose from the lighter 130/140mm Fuel EX Gen 5 with better parts for the price or the more robust 140/150mm Fuel EX Gen 6 with more adjustability.See the bikes

Everything you need (and nothing you don’t).Learn how
Will my bike have a curved top tube?
Smaller frames (XS and S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
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.
RE:aktiv with Thru Shaft gives you unmatched grip and control with a shock that reacts to the terrain faster than anything else out there.
Trek's Straight Shot frame design optimizes the stiffness-to-weight ratio for a more responsive ride. You'll be able to push harder and stay more planted on your line when the going gets rough.
This suspension calculator will help you optimize your suspension settings for your riding weight. Simply follow the steps to find your best set up.
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.
