Our favourite Trek
The Fuel EX proved itself a happy climber and descender. From slabs to roots and square-edge hits, the Fuel EX handled it masterfully. A damn fine trail bike right out of the box, no matter your riding style.

Fuel EX – full-suspension trail bikes to go bigger and faster
Holding the cards to perfect trail days
Shuffling things up and dealing a royal flush of adjustability, capable handling, and a grin-inducing playful ride, the Fuel EX is back and more ready than ever to tame any trail. It packs in longer-travel suspension to broaden the horizons of a trail bike into bigger terrain and faster speeds, with a lively character that begs to be let loose on the singletrack. From lacing lines through tight aspens, to rallying root lattices and barrelling through berms, any trail, any way, the Fuel EX is up to get down.
The Fuel EX is a masterpiece
The Fuel EX absolutely devours chunky terrain while still retaining the ability to tractor up steep climbs. I have become convinced that a bike with long, stable geometry and mid-level travel really can provide the best of both worlds.

Loves to ride fast, both up and down
The Fuel EX is a highly adaptable bike that feels comfortable in a really wide variety of terrain, but doesn’t confuse itself for anything more or less. Bike riders, rejoice.

Ready for anything
The Fuel EX’s geometry feels ready for just about anything. There’s plenty of traction for climbing and a nice fluttery feel on descents, calmly smoothing out the trail chatter.

That 'juuust right' feel
The Mino Link lets you quickly and easily tweak your geometry, so your bike is always tuned perfectly for the terrain and your riding style.
Slack or steep, the choice is yours
Install angle-adjust headset cups (sold separately) to tweak the 64.5-degree head tube angle a degree steeper or slacker to your liking – all without impacting your bottom bracket height.
Business at the front, party at the back
Craving the nimble ride of 27.5˝ wheels but don’t want to sacrifice the speed of a 29er? No need to choose. The Fuel EX is mullet-ready, just throw Mino Link into high, toss on a 160 mm fork and get ready to party.
Adjustable Leverage Rate
Easily adjust suspension progression with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails loaded with square-edge bumps. Flip it to More progressive when you’re riding fast, hitting big features and don’t want to bottom out – or if you want to roll with a coil shock.
Sized for every rider
Whether your head is above the clouds, or you stand at a lower altitude, the Fuel EX’s huge size range provides an outstanding fit for every rider. If you fall between XS and XXL, you’ll be ready to saddle up with size-appropriate wheels and chain stay lengths for a ride that’s fine tuned to you no matter your height.
Geometry
01
The slack and stable 64.5-degree head tube angle complements the longer-travel suspension for more confidence.
02
A steeper, 77.2-degree seat tube keeps you perched for pedalling efficiency on long fire roads and quick, punchy climbs.
03
Longer reach compensates for the steeper seat tube, so you stay comfortable in the cockpit and ready for what’s around the corner.
04
Size-specific chain stays give smaller riders more nimble handling, while taller riders get better front wheel traction on climbs.
New frame, new possibilities
The Fuel EX’s new generation opens up possibilities for riders who want full customisation. Broader shock compatibility allows for more aftermarket upgrades, like coil shocks. A larger 34.9 mm seat tube accommodates larger, more robust dropper posts.
Non-stop suspension
Trek’s exclusive Active Braking Pivot keeps your suspension active while you’re braking (which is often when you need it most).
Clean and easy
Internal routing tunnels eliminate cable rattle and simplify maintenance along with a robust threaded BB. A bolt-on downtube and chain stay guards protect against rock strikes and shuttle damage while muting noise from the trail.
Stow it, don’t show it
Stash your ride essentials with in-tube storage on all models – both carbon and alloy. The included Bontrager BITS bag keeps all your odds and ends organised.

Top Fuel
Sometimes less is more. The Top Fuel is a shorter-travel full-suspension down-country bike ready for all-day pedal-fests. It’s just as happy hammering out miles on smooth-rolling cross-country singletrack as it is dipping over the backside of the mountain to explore off-the-beaten-track adventures.
