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 lightweight Alpha Platinum Aluminium frame with internal cable routing, a Straight Shot down tube for extra stiffness in the rough and a Knock Block steerer stop to protect against spinning bars. A 140 mm RockShox Recon RL fork, 130 mm of rear travel with a RockShox Deluxe Select Plus shock, a durable 10-speed Shimano Deore drive train, dropper post and hydraulic disc brakes.
The final word
Full suspension performance without the sticker shock. Fuel EX 5 has the same frame and suspension tech found on our higher-end alloy Fuel EX models. Quality RockShox suspension, a dropper post and a Shimano 1x10 drive train make for an ideal introduction to the world of full suspension trail riding.

favorite_borderWhy you'll love it
- You're getting incredible features and the latest mountain bike innovations at an exceptional value
- It has the capability of far more expensive trail bikes: it shreds singletrack and can even handle marathon races
- The dropper post lets you lower your saddle on the fly so it's out of the way on descents
- The RockShox fork's Solo Air spring can easily be adjusted for a specific rider weight, and it's lighter than a coil spring
- 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!'
'The 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 pedalling, and to pump and pop off when you're playing.'

'Good at pleasing everybody.'
'The 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.'

'An absolute trail rocket.'
'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.'

‘Perfect all-rounder’

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 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.
Trek's Straight Shot frame design optimises 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.

Tubeless Ready wheels and tyres
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. Just add TLR rim strips, valves and sealant.

Mino Link adjustable geometry
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.

Control Freak cable management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout and dropper post lines to be routed through the frame for clean looks and the ultimate custom set-up.
