Please select options


There is no offseason. The Jamis Roughneck is a true fat bike with 26x4.5” tires on 80mm Sun Ringle MuleFut wheels, giving it the capability to float over snow, sand, and soft mud with maximum traction and ease. Its air-formed aluminum frame and fork make the most of the lightweight material, putting strength where it’s needed and shaving weight where possible. Your terrain options are nearly limitless, with a wide-range Shimano SLX 11-speed drivetrain and powerful, easily serviced TRP Spyke brakes. Plenty of water bottle, cargo, and rack mounts on the frame and fork provide versatility to load up for any expedition. What’s stopping you now?
