I was joking, I'm merely a situational bike thief when as said friends loose keys, etc..
Old bikes, new bikes doesn't really matter, at least in Amsterdam, nor does the neighbourhood, hell if it's a crazy nice bike, most thief's might assume it's a bait bike from the police. It should look average, and if you have a Brooke's saddle, take that with you. Even crowded places don't help, as you can see in this Neistat video, people do jack shit:
No better then any other expensive brand, i.e. AXA, Kryptonite, etc... I'll snap their heavy cable in seconds.
One more tip: One of the best solutions against stolen wheels is Pitlock or infiniti3D lock nuts, but then even then that doesn't always help, if they want the bike or a part, they will find a way to get it. Such as just sawing straight through your fork.
