That sounds like one nice seat! Bending ply or snake ply, I will have to make my seat out that stuff. Any thoughts on the main pivot? I like the simple bottom crank design but I want a design that is simple looking, sleek and adjustable angle by a few degrees to account for other riders weights and lengths. Good to see the group is active, very quick replies from you guys is great! I have shown, told a few work mate and friends the web site and they are keen to see me finish my python and ride it.( and a few think am crazy.) How smooth is the ride of these bike with 700c or 26 inch wheel on the road( no off road) would I need suspension? I intend to only use the bike for touring on the road. I'm thinking no suspension to save weight. Thanks guys for your help.
