Things aren't quite as bad in Liverpool where the Citybike thing is still going... possibly because they're such big heavy clunkers that the kids don't want to steal them.
But a number of stations away from the city centre have been abandoned due to the fixtures being destroyed by vandals, which is a shame. One situated in a park near me was ideal for... having a ride round the park, obviously, but it was also on a handy 2-mile route into the city which was great for a quick ride in to the shops. But it was wrecked.
Perhaps ironically, the same park used to have a police station at one entrance - but they closed that.
