Another good title for these bikes would be "Miles and Miles of Smiles. They've certainly brought a lot of smiles to people's faces.
When I made my first two or three small bikes back in the early 80's, I hand formed the handlebars. It was time consuming, and the results were less than perfect.
I thought to myself, "this is ridiculous, there must be a better way". So, I came up with a simple fixture to form the handlebars so that they are all the same in shape and dimension.
