I built a similar frame 20 years ago from a 24" bike, but sold the frame and never built the bike. this started out as the remains of a 70's Schwinn Varsity I got for 10 bucks. sold the parts I did not need and got the bike for less than free the original Idea was to build it as a 20", but it did not look right with the small wheels, so I put these 26" junk wheels on it and this will be the way I am going to go. if I do ever build a 20", I will do the same thing but cut the seat tube shorter to match a Sting Ray. did some figuring on photoshop...... I just eyeballed everything and started cutting it up and ended up with this: here's where I am now, with some junk mock up 26" wheels. probably going with a banana seat and sissybar. paint will be black and creme with some scallops using the Schwinn stencils you see on ebay. I'd like to put an "off brand" springer on it of some sort, it will have truss rods at the very least. it will be needing some looooong handlebars, I'll probably have to make my own.
