Thanks for the responses so far. I'm sticking to the classic design for this first time. I need to know how that one handles and how well it works in ny terrain; then I might consider an alternative design. Besides, many (most models actually) Brazilian recumbents have small (20 inch) wheels up front. It's not considered a problem per se, even in our less-than-perfect streets and roads.

I believe I've just found the right person to help me with the welding (to do the whole welding work actually). A skilled, experienced welder who happens to be a passionate cyclist and even lives car free! I think I got him really interested.

I'm also on vacations right now so I have plenty of time.

I'm lacking more data and general info from those who have actual experience with box bikes. Please chime in folks!
