My son is getting old enough now that he needed to pass down his kids bikes and move to a semi-adult size. I took on the challenge of designing a 700c frame for a 4’9″ frame that he could grow into over the next few years. A lot of research and investigation yielded some geometry options. I eventually worked out standover, etc. and the part mix. We finished it off with a mix of chrome logos and orange metallic paint.
