2026 TREK FUEL EX 5 Lithium Grey/Trek Black Splatter | Trail Bikes
Fuel your wildest rides
Got an appetite for everything? Meet the Fuel. From fast and loose steeps to side hits, high alpine climbs to rough countryside boulders, the Fuel is a rip-anything trail bike that adapts to however and wherever you ride. Three configurations satisfy any trail rider, whether you’re after the balanced handling of a true trail bike, a playful and poppy ripper, or a long travel crusher. Add in refined frame details and award-winning suspension kinematics and the Fuel delivers the custom-tunable ride you’ve always dreamed of.

Fine tune for full send
Only you can define your perfect trail bike – that’s why select Fuel models are available in three adjustability-packed configurations, all from the same chassis. Start by choosing from the do-it-all EX, the pop-happy MX or the point-and-plough LX, then tweak and tune your build just to your liking. Or, if you’re starting with a Fuel EX model, you can change your set-up with aftermarket links. Whatever your set-up, you’ll get a geometry-corrected ride with the suspension leverage rate to match.

Fuel+ EX
With 29” wheels and 145/150 mm (rear/front) travel, the EX is the classic Fuel configuration. You get the most efficient pedalling and the most balanced handling, making it the right bike for a massive variety of riders and terrain. That’s why the Fuel 5, 7 and 9.7 only come standard as an EX.

Dialled to be different
Many trail bikes allow you to swap 29ers for mullet or roll with different shocks, but most don’t adapt the frame to optimise your new set-up. This means that you end up compromising your ride with suspension that doesn’t feel quite right, off-kilter geometry or a bottom bracket so low it causes pedal strikes on every climb.
The Fuel is different. We don’t just throw on a few new parts and call it a day, because we don’t want your component selection to compromise the geometry or quality of your ride. All three versions of the Fuel start with the same frame, but the magic in these builds comes from interchangeable rocker links and shock mounts that adapt the chassis for your dream build.

Open triangle
An open front triangle gives you loads of room for stashing big water bottles and additional accessories, like frame bags or mini pumps.
Adjustable leverage rate
Tweak your leverage rate with the flip of a chip. Go less progressive for a plusher feel when you’re deep in the travel or more progressive for big features, more bottom out resistance, or running a coil shock.
