I haven't purchased a single thing yet, no bike, lock, or anything yet, so paperwork (receipt) should be easy, and I plan on registering the bike with the police ASAP.
Thanks for mentioning that, I'll go with Kryptonite then rather than Onguard.
I'm not hitting the streets of new york, so just commuting to places and riding to school will be what I'm doing. Would any Kryptonite ulock with cable lock do?
