Fuel EX

The perfect trail bike

The world's best-loved mountain bike keeps getting better. Fuel EX continues to set the bar for full suspension trail bike versatility, bringing race-day tech to all-day adventure.

Want a rugged, capable long-travel trail bike, and a nimble XC bike? Get both with Fuel EX. Whether it's your millionth mile on the trail or your first, you'll love this bike.

  1. Doubly stiff: Boost148/110 Wider 148mm rear and 110mm front hub spacing on 29ers creates stronger, less flexy wheels and allows for wider tires, shorter chainstays, and more chainring options.

  2. Smooth, controlled braking Our patented ABP (Active Braking Pivot) keeps your suspension from stiffening up when you're on the brakes, giving you confident, steady control.

  3. Trek suspension package Advanced tech, like ABP (Active Braking Pivot), Full Floater, and RE:aktiv, makes Trek the best-riding full suspension bike.

  4. Short, lively chainstays Thanks to Boost148, we can shorten the chainstays on 29ers from 452mm to 437mm for a more spirited, lively ride.

What people are saying

The bike ate long climbs and crux moves on the way up, blew through technical trail with incredible agility and efficiency, and rallied descents I would have thought out of its league


Trek's new 2016 Fuel EX 29 is one of the fastest, yet most capable trail bikes we've ridden this year. The benefits of the larger wheels were there without sacrificing the bike's ability to play around on the trail. We all agreed that this bike was a blast to ride.
