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.
