Can any of you experts help me narrow down the exact make/model/year of this bike? I know it is a Chicago-built Schwinn and most likely a Stingray Lil-Chik but I want to make sure. I also am not sure how to figure out what year the bike is, even though I have the serial number. I tried looking up the serial number on the various Schwinn Serial Number sites but no luck:
Serial Number (KC18525) - I couldn't find that KC was a valid combination so this has me confused. Thanks!
