Weird Bike Wednesday - Bicycle with Car Tires

Here's the ultimate fat tire bicycle. Mr. Mash began the project with an old BMX bike and two car wheels. Then he did some pretty serious modifications. He had to remove the centers of the wheels and put in his three spoke arrangement. He couldn't run a chain from the front sprocket directly to the rear hub, so it was necessary to add an intermediate shaft. Modifications were made to the frame and fork to accommodate the much wider tires. You can get all the details at the Instructables website.

Here's a video of it in action. You will notice the rider isn't going very fast. That's not too surprising when you consider that the average car tire weighs 25 pounds.
