Re: Need an ID on this Bike
looks like a schwinn panther style straightbar frame. Norm from Venice bikes, silverbear, and sportscarpat have all built up really cool ones.
the handlebars aren't original, and it's hard to tell from the picture what else might not be correct, but it has a skiptooth chain which would put it in the 40's.
schwinn serial numbers are well documented and can pinpoint the bike to the exact day it was made. usually.
at a good price, it's an awesome bike to motorize.
