Just picked this one up today. 1960's Mattel Stallion. All chrome bike including frame, neck and forks. Looks like they will all clean up pretty well. Might need a new rear wheel, though. Missing a few spokes in rear that look like they have pulled through. Not sure how to fix that. Seat is in good shape, no tears and embossed with Mattel logo. Looks all original except the pedals. The tires are original, I think. They hold air, but otherwise are shot. 20 x 1.75 up front and 20 x 2.125 in the rear. Not sure what kind of fenders these had. If anyone knows anything about these bikes, please let me know. New to the bike hobby, open to suggestions on what to do with this one. To Rat or Not to Rat.... that is the question.
