Not sure what it is that draws me to bikes with fat tires. You know, like the Mongoose Beast, Dolomite, and Hitch style bikes. Yes, I know that they are horribly inefficient and have extra weight and rolling resistance. But they just look so cool. So, why not take it up a notch by using your old car tires and pop them on your bike? Well that is just what Mr-Mash did with his instructable. He shows you how to put car tires on an existing bike. The only change I would make is to add an electric motor. More pictures after the break.
