Evanston Police Bike Auction is May 30th. Every year they auction 50-150 bikes to the highest bidder.
Many of the Bikes are clunkers, but some are nice (Cannondales and Treks) Some are former police bikes being retired, some are recovered stolen property that’s unclaimed, some are bikes abandoned by NU students after school year ends & confiscated by the police.
I bought a halfway decent bike there years ago. They usually have a ton of kids bikes.
