$3600 seems like a lot for something that doesn't have to much research and development. Don't get me wrong, It's a very COOL bike, and I'm not saying it isn't worth it. But, you gotta ride that thing HARD for a year, to find any defects (weakness) in your design. Personally I won't sell a bike that I've built from scratch, or one that I've "radically" changed the geometry on. To many people out there waiting to SUE ya..... I hope you carry "liability" insurance.
