You want to see how they "harvest" the bikes in Cambridge!
They have a few guys walking down the road, who crop/pry all the locks off, then another guy picks them up and puts them in the back of a Transit van, which is being driven along slowly.
They just take them all, regardless of what lock you have.
They did the street I was staying on one night. Didn't hear a thing, in the morning, all that is left is a few broken bikes they didn't want, and a few dead locks! 30 plus had gone. My brothers was long gone.
The police said they "knew". No insurance, no crime number, it wasn't worth the hassle...
