Stop me if you've heard this one before. A man walks into a bicycle shop, hears about a canoe made of cardboard and is inspired to make an awesome, fully-functional cardboard bicycle.
Sound far-fetched? Wait until you hear how his guy actually did it.

Essentially, he made the basic shape for each part with multiple layers of cardboard and then attached another piece around the outside edges to reinforce it.
Then, he sanded and painted all the parts and put them together. Pretty impressive considering his first prototype looked like this:
