Re: "police declined to pursue the matter"
Why are you buying an item to then abandon it in public for the majority of the day?
My husband would take train to nearest station to work, then bicycle the rest of the way in decent weather (the bus was circuitous, crowded, and irregular in schedule). He would buy the cr@piest bike that still worked from a local garage sale, usually around $20 - $30, and a decent but not great lock. He could take the bike inside at work, but had to leave it at the station overnight.
The rules for taking bikes on commuter trains near Chicago involve: must be outside of the rush hours, and then only a few allowed per trip per car on the train (too many bikes when the train got to your station? sucks to be you). So beginning of warm weather he would take an out of rush hour (usually arrange to come in late) train with the bike. Work late and bring the bike when the weather got too cold and snowy.
Bike got stolen once, couple of times the gears were stolen off the bike, but the rest left. Yeah, that's how bad the bikes looked
Worst problem was that despite wearing high-vis vest he got bounced off his bicycle by a numpty turning into the dense traffic without looking for bikers. Fortunately, bruised but not badly hurt. His insurance sent a check that would have bought a VERY nice bike, but Bob still bought a junker and kept riding til COVID and then retirement ended his commute.
