I had bikes as a hobby as a kid in the 70's and 80's also. My freinds and I used to build chopper bicycles by cutting the forks and putting them together, good times. I'm building one now using a 70's german 20 inch bike with newer parts. I added a pair of 16 inch forks to the 20 inch forks. It came along pretty good, just wish my ape hangers would hurry and get here so I can finish it up.
