I was in Manhattan the other day and I ran across the Metrocard bicycle, or perhaps just one of many of the Metrocard bikes. This one was about 5 blocks from Grand Central Terminal.

I have read about this bike (or maybe just one of them) and had always thought it was an artistic use of something that many New Yorkers generally find to be disposable.
I wouldn't do this to one of my bikes. But then I don't ride in Manhattan. It was nice to see this bike.
Wish I had my real camera. The picture I took with my phone just doesn't do justice to this bike.
