I just picked this bike up the other day in order to resurrect it back to the living. I've tried looking around to figure out what year, and if it would be worth anything if I tried to sell after restoring. It's a 3 speed Schwinn Speedster. The frame serial starts with a K and all the lists that I have seen supposedly starts with an A. Thanks for the help!!!
I was thinking of keeping it and will if I have enough space to. Do you know about what year it is?
Maybe early 60s. I vaguely remember seeing an ad for this model in Boys' Life Magazine, which I stopped getting around 1965. The curved top tube allowed it to be built with a shorter seat tube--a forerunner to compact frames, I guess. It was marketed toward younger teens who wanted a tourer with a Sturmey-Archer hub. Wish I remembered the model name.
I'm pretty sure the camelbacks had 26" wheels; they were just a shorter version of the Speedster. The OP's bike looks to be a '70, based on the five-spoke chainwheel and two-tone saddle. The second letter in the serial number is the key to the year; the 'K' means October.
Even with 26" wheels, I'd still say $50-$75. Where I live, it could be flipped for $120-$140 once it's cleaned up; lots of college girls looking for a short-framed campus bike.
And to answer OFG's question: No kid wants a three-speed. They don't want a road bike, period.
Speaking of tire size, There are the 26" that schwinn uses and there are the 26" that everyone else uses. It's worth learning the difference, here's a link to Uncle Sheldon; http://sheldonbrown.com/tire-sizing.html
