Not that I don't appreciate all the respect. But, I do have an artificial leg, and while it only does probably 25% of the actual work pedalling, it's not like I literally only use one leg.

Here's a creative question though:

I'm building my ss/fixie and I only have one leg. I need a name for the bike that I'll get cut out in vinyl and attach. I figure there has to be a good way to incorporate one leg/one gear. But creatively.
