On the purely aesthetic side, looks like a nicely balanced frame to me. What's the wheelbase? The position of the bracket between the wheels is like 'the golden section', if anyone is familiar with that? I guess this is perfect geometry for someone. If it's a design to cope with 'Paris-Roubaix' and such, it may have been designed to be used in conjunction with some prototype suspension-handlebar stem which took up a lot of vertical space but not much horizontal space? Just a thought...
