Years ago I lived in a house in the inner city and at least 3 days a week I would have a bike in the front yard or driveway. I would carefully roll them behind the house being careful of fingerprints. I would then call the police and report I had a new one. They would say thanks and never show up to get the bikes or investigate. Sometimes I would have 6 bikes back there some of them quite nice road bikes. The number would go down as whoever was stealing them and leaving them would re steal them and take them someplace else. I never did figure out who was taking them but it wouldn’t have taken Sherlock Holmes to stake it out and catch someone. There was zero interest on the part of the city. They would tell me if I could bring them down to the impound they would have them there for people reporting a bike missing to look at. I didn’t have a good way to get them there so I said you want them come get them, but they never did. People would grab a bike and ride it close to home dump it in my front yard and then cut thru my back yard to the street behind. I was tempted a few times when a nice bike showed up but no way was I going to keep these bikes. There was no need to ask around the neighborhood about these adult bikes, a kids bike I might and a girls bike might be different. Back in those days bikes were being taken mostly for one way transportation not for trying to sell them.
