Stealing a bicycle isn't Grand Theft Auto like stealing a car. Its also a lot easier to steal a bicycle than a car (although some cars are very easy to break into). Different areas have different crime statistics. In my town when I was shopping for a bicycle twice in the same day I went into a bike shop and someone was there looking for their stolen bicycle to see if someone brought it in. Coincidence? Bikes get stolen all the time here. I wouldn't leave mine locked up out of site for even an hour. If I needed to run errands by bicycle I would sure as hell buy a walmart bicycle for that, and lock it up.
