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 here 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.
