Out here in SoCal they find bikes and disassembled bikes by the hundreds or thousands in the homeless camps when they get around to trying to clean them up.
Had an old beater of a Schwinn Varsity with rotten tires and inoperable brakes stolen off a second floor balcony a decade back or so.

I go past a couple of auction yards once in a while and I've noticed over the last several years that they have acres of bikes stacked as tight as they can be put together. I imagine the flow of missing bikes eventually ends up here and the guys taking them across the border have an auction's bill of sale.

LEO property rooms can end up with stacks of bikes (and everything else).
Sometimes they are auctioned individually and sometimes in joblots.
I was going to attend one of the auctions in Memphis in the early 2000s and 4-5 hours before the event it was impossible to get anything like nearby. Worse than it used to be hiking in to the airshow at Edwards back before 9/11 when they still had them on base.
