Reviews

"A world-class trail bike"

"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 pedaling, and to pump and pop off when you're playing."

"Good at pleasing everybody"

"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 at it."

"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."
