El Oso Dos

* Required Fields

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, the Diamondback el Oso Dos. We made this fat bike quick by designing it around a rigid platform to shave pounds. Thru-axles front and rear add stiffness for enhanced steering precision. Let the gigantic tires take care of the suspension — something they do quite well. That means you can ride this bike up and over just about anything and under any conditions, including through snow, sand, mud. Even when the weather gets bearish, el Oso Dos will keep you in the saddle.
