Foldable bicycle with travel case.

Bicycle commuting rocks. It's healthy, safe, fast, cheap and the only emission is what the biker breathes out. But it does have it's problems. One is that bikes generally have a very awkward shape. If there is no bike rack, or if you want to go somewhere with your bike, you're reduced to lugging a very cumbersome package around with you.
Well what if there was a bike you could fit in your trunk, that was the size of a briefcase, or that you could take on the subway. That sure would be nice.
