Tandem A-bike concept drawing

I was interested looking at the idea of a tandem A-bike type folding bike. As it stands now, it is only a drawing concept, nothing more. Here are some drawings of the design. I have no idea if it would work or not but it is fun to draw it up at least to see if the concept works or not. On paper at least, it works out.

The drawings shown show the drawing of the single seater version and the tandem set-up by basicly copying single drawing and adding 20" on to the bike. I then altered frame to make it into the tandem set-up. A drawing showing the tandem folded up is included on the page.
