I've had this idea in my head for a while. I couple of years ago my wife and I set out to simplify life, in doing so I looked for ways to simplify my cycling. I already rode single speed mtb and this lead to my riding single speed and fixed on the road. I've always loved working on bikes and have enjoyed rebuilding on old road frames into Fixed Gear Bikes. I also have many years working in metal fab, and with my cycling addiction I attended the Brew Frame Building Class in NC to and built a SS MTB back in 2007. Sometime last year I saw a photo of a fixed gear bike made from square still tubing so over the Christmas Holiday I worked and built a frame like that using the things I had learned in the frame building class. I loved the way it turned out and even posted a photo on this forum. I building that frame I began again thinking of how to simplify the frame even more. That when the idea of the Plus bike come in. Here is a photo of the prototype frame on the Jig. This weekend I while researching frame design I came across this. The Cogent No. 18 safety from 1887. Similar to what I have been working on!
