Very interesting about old designs. Some of those low carbon fiber recumbents look amazing. I am sure they must be fast, cuz they sure look fast. My only question is how are hills. Also recumbents do not use upper body at all.? Another thing if you factor in off-road capabilities. I wonder if any thing made using both upper and lower body in a running style. I did see one of those "stair master " type , 2 wheeler go by once...
