I live in the Uptown area of Chicago and decided to take action on a bike that seems to have been abandoned. A 1972 Schwinn Collegiate has been locked to my apartment’s fence for about 6 months (coinciding with a lot of move-outs) and surprisingly the owner left the key in the u-bar. We have bike storage areas, so it seems odd that it would be left there. Even more surprising, the bike has remained undisturbed during that time except by property maintence workers who mulch the area. Over the 6 months in the elements, I’ve watched the tires go flat and the bike collect dust and grime.
I came across this site and looked up the serial number found on the body. There’s a listing of the bike with photos showing it in better condition. Unfortunately, the listing does not have any contact info for the owner. How might I try to get in touch with the owner to see if (1) they abandoned the bike or (2) they simply forgot they left the key in the u-lock for 6 months?
