    Doubt it's a '57... Looks like some variant of the 5 speed Stingray or Fastback. Where is the serial, and what's the #? I'm no Schwinn expert, but have had more than my share of Stingrays way back when they were $5-$10 bikes used (around '76...).

    That serial # is confusing to me... The frame sure looks like either a Manta-Ray or a Fastback 5 speed frame. I'd bet money on that... Thing is though, those bikes weren't around 'till mid or late '60s. That brake bridge on the frame you have is intended for a caliper rear brake, which indicates a 5 speed frame, not a coaster brake model. I seriously doubt they made a 5 speed model in '58. The first Stingrays weren't 'till about '63-'64. Are you sure you're reading the # correctly, or that no one has altered that #? It was REALLY common for those to be stolen & parts switched around in the '70s...

    Fastbacks had a straight downtube, so that can't be it.

    Yup; you're right... I wonder what other Stingray variants had the shortie seat stays that stop at the seat tube like that one... I'm sure some Stingray expert will ID it.

    it don't look like the frame or # has been altered and it doesn't have a welded on kickstand also the holes for the nameplate are not like stingray they are like a 50's( the crank has the marking"SA 9 69")the other frame that was found with it was a 20" schwinn with a skip tooth sprocket and had 2 single bars on top.I guess its a mystery for now.thanks for any help now and in the future Junior

    I wonder then if your dating from '58 may be correct... Something tells me that Ashtabula crank is a '69 though. Maybe the frame's a "pre-Stingray"- the Stingray's daddy! Whatever you do, please don't make a "lowrider" bike out of it... That should be a good one to restore as original.
