Overview

It's right for you if...

You're ready to go full suspension, and you want a versatile trail bike at a great value. You want a ride that's sure-footed, capable, and responsive so you can stay in control no matter where you're riding.

The tech you get

A sturdy aluminum frame with a Knock Block steerer stop to protect against spinning bars. A 140mm RockShox Recon Silver fork, 130mm of rear travel with an X-Fusion Pro 2 shock, a durable 12-speed Shimano Deore drivetrain, dropper post, and hydraulic disc brakes.

The final word

You get full suspension performance without the sticker shock. Fuel EX 5 has the same proven frame technology that riders have loved over the years, with parts chosen to keep the price tag low and stoke level high.

See it in action

favorite_borderWhy you'll love it

  1. You get a high-end ride at an exceptional value with frame features like Boost148 and ABP that give you confident handling and room to upgrade parts as your skills grow
  2. It has the capability of far more expensive trail bikes: it shreds singletrack and can even handle the occasional XC or enduro race
  3. The dropper post lets you lower your saddle on the fly so it's out of the way on descents
  4. The RockShox fork's DebonAir spring can easily be adjusted for a specific rider weight, and it's lighter than a coil spring
  5. We expanded our size range to ensure a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝, and sizes M to XL get 29˝ wheels

"A world-class trail bike"

"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."

"Good at pleasing everybody"

"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."

Features

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.

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.

Straight Shot w/Knock Block

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.

Control Freak Cable Management

Boost148/110

Boost148/110

Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
