I am not new to bicycles but am starting a new project and could use a quick tip. Here goes; my project starts with a 1960's schwinn 26 inch frame. What I want to end up with is a Krate style bike but big enough for me to fit comfortably and go cruising. My question is this; if I want to use a 20 inch front wheel and a 26 inch rear wheel to retain that hot rod 70's Krate styling, what size of springer front end should I buy? I am afraid that the bike will be off balance from front to back if I use the OEM Krate front end. Any help on the matter will be greatly appreciated. BTW, I saw a pic of a very similar bike on the Ape Hangers only club pics so I know it is possible.
