Need to know what bike I have the serial # is LP9 0246 badge # is 0589
That serial number is consistent with a Schwinn frame produced in Chicago in November 1978. The numbers on the headbadge refer to the 58th day of 1979, which presumably was when the full bike was assembled, so it was probably a 1979 model.
You can find old Schwinn catalogs online at Bikehistory.org, so I suggest you look through the 1979 catalog and see if your bike matches any models there.
