This is an Instructable created by user Mr-Mash detailing how to build a bicycle that rides on car tires. You know, in case that was something you were considering building but weren't sure where to begin. Apparently he started with an old BMX frame, which was heavily modified and widened. Personally, I would have just started from scratch, but that's just me and I have has absolutely zero luck building anything that doesn't fall apart or explode in my face. My parents actually moved so we'd be closer to the hospital.
Keep going for a couple more pics and a video of the bike's first test ride.
Thanks to JTS, who wants a bike that rides on monster truck tires that you can use to drive over traffic at red lights. Now you're talking my language! And that language is gibberish that will never work.
