2019 Specialized Fatboy SE

If having fun for the sake of having fun sounds appealing to you, "going fat" will change the way you ride forever. The security and control that the wheel system found on our Fatboy SE provides is unparalleled. You get dramatically more traction, grip, and floatation than with traditional mountain tires, all without sacrificing much to climbing efficiency.

The end result is easy to explain—you have way more fun. And to make sure of it, we built the Fatboy with a durable, no-nonsense list of components that are low-maintenance and eager to perform season after season.

- The frame features an M5 alloy construction that provides the ideal blend of efficiency and durability, while the geometry creates a roomy top tube and short chainstays for easy climbing and confident descending.
- Our alloy fork with air-formed legs is lightweight and pairs up perfectly with the fat wheel system to soak up trail chatter and bumps.
- The Shimano 10-speed groupset features a wide gear range that delivers climbing and descending efficiency in spades. On top of this, the one-by setup is notorious for being next to impossible to drop a chain with, plus it provides significant weight savings in comparison to a standard two-by setup.

      I just bought it today and took out in the desert twice. It handles so well over sand....deep sand. The gears are nice and tight and shift very well. I love the new hand grips work well with my arthritic thumbs. Its super fun to ride and nothing slows me down. They say it's not fast but I sure was movin! Broke my record climbing a 1.5 miles stretch.
