Schwinn Stingray, for sure
+1. I had one with a 2 speed hub you shifted with the pedals, a slick back tire plus a springer front end. Sweet. Bought it for $25 from one of my buddies and his dad almost killed him for selling it so cheap. (The friend who sold it to me is now in the District Attorney's office in Tarrant County, but I think it's been long enough now that he won't file legal actions to retrieve it).
