A few years ago I was at the Israel Day parade in New York and there was a group marching there called something like "Jews on Bikes" or something like that. At the time I remember thinking to my self "Now there is a Jewish organization I can join".
Anyway there are a few Jewish Biker organizations that are now operating. I wish I was a biker. I never really had the time or money to get a bike, but I wish I did. It really is a fantasy of mine. There is an article about them here finally giving them some of the recognition they deserve.
