2020 specialized Fatboy SE
Manufacturer Description
It’s simple: fat tires—really fat tires—equal more fun. Especially if you define fun as insane levels of traction and rides that take you deep into places you never dreamed bikes could go. We built the Fatboy SE with durable, no-nonsense components that perform season after season. A VERY FAT FLAVOR OF ADVENTURE It boils down to a single word: adventure. The Fatboy’s massive tires (26x4.6”) float over rocks, roots, sand, snow, ice…. Let’s put it this way, if it’s part of mother earth, those big tires will roll right over it with a mix of comfort and traction that’s unrivaled. Get out there. • Premium, M5 alloy frame is light on the scales, yet holds up to any adventure. • Alloy fork with air-formed legs pairs perfectly with fat tires to erase trail chatter. • Shimano single-ring 10-speed drivetrain is simple, accurate and reliable.
