Trek Fuel EX 5 Gen 6

Fuel EX 5 is a full-suspension trail bike that's ready to handle it all. With 150mm front and 140mm rear trail-taming suspension, a Shimano 1x12 drivetrain, a dropper post for getting low on descents, and hydraulic disc brakes, Fuel EX 5 hits the mark as a high-value, high-performance mountain bike with exceptional versatility.

• Fuel EX Gen 6 gives you 140/150mm of travel and slack, adjustable geometry for an extra capable ride, plus, in-frame storage on all models — even alloy
• We expanded our size range to ensure a better fit for all riders, and use the best-fitting wheels for each frame size: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝, and sizes M and up get 29˝ wheels
• 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
• Its tubeless-ready wheels and tires will boost traction and help to reduce flat tires on the ride

Internal Storage

Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.

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.

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.

Adjust the sus for full send

Adjust leverage rate with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails with square-edge bumps. Flip it to More progressive when you're hitting big features and don’t want to bottom-out, or when you want to run a coil shock.

Size-specific stays

Size-specific chainstays provide balanced handling to keep the ride nimble for smaller riders and improve front wheel traction on climbs for taller riders.

Business in the front, party in 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. Fuel EX is mullet-ready, just throw Mino Link in high, toss on a 160mm fork, and get ready to party.
