Titanium O’Beast

Titanium Fat Bike Purpose Built From the Ground Up

Here at Carver bikes, we pride ourselves on having an eye for the newest developments in the industry and we’re often one of the leaders when it comes to new offerings in the bike world. Our fatbike is no exception…we designed and built up our first demo almost immediately upon the arrival of Surly’s breakout Pugsley. Since those days of obsolete 150mm/100mm fatbike spacing and treadless tires, we have been slowly polishing our frame design and build spec. Now, we’re ready to offer our O’Beast frame and kit in a complete bike that is certain to turn heads. Featuring our 570g Carbon O’Beast fork as well as workhorse componentry, the O’Beast promises to deliver the lightest and most comfortable ride no matter if you’re hitting the trails, putting along on the beach, or doing a long-distance tour across Greenland.

  • 12 sizes from 14″ to 25″
