I had my bike stolen last year in Chicago (my wire chain was cut and bike was gone..Yes, yes I know, it was stupid.). I recently purchased a new bike and had special nuts/bolts put on the wheels and seat that I've read are about nearly impossible to break off. I also purchased a short U-lock (Kryptonite). I don't plan on being in the city biking too much (I live in the suburbs), but I wanted to make sure it was as safe as it could be and any other tips. Glad to be in the community!
P.S. - I would of put this in an appropriate forum but I didn't see one on the main page.
