The fastest human alive topped out at 27 miles per hour. Fastest bear? 35 miles per hour. The takeaway? Bears are fast; particularly this bear, el Oso Dos. We made this bike quick by equipping it with a light, strong double-butted aluminum frame and sleek alloy air-formed fork. We specifically designed el Oso Dos around a rigid platform to shave pounds and let the gigantic tires take care of the suspension — something they do quite well.
Fast, sleek … el Oso Dos is also an out-and-out fat bike, and that means you can ride this bike up and over just about anything and under any conditions.
