When you come to live in Amsterdam you soon copy the natives, and make sure your bicycle doesn't get nicked. One tactic for this is to use good locks, another is to ride around on a bike that is just too unattractive to steal, and you don't really care about.
But when you don't care about your ride, you don't care that much either when it breaks down. Especially since repairing it or taking it to the municipal waste yard costs more money than getting another wreck.
Many bicycles are abandoned daily in Amsterdam, and the city removes them from after some time. Those bikes end up in a depot, where their owners still have a last chance to come and look for them. Before the end.
