It is beautiful . . .
. . . but, I will agree with others that the step-through makes the bike look structurally flawed.
Removing the bar between the legs will make it easier to get on the bike, especially for those who have physical limitations. Maybe if they borrow an idea or two from Vespa which also doesn't have a triangle frame, they can make this bike work.
My next bike will be a recumbent and I think designers, such as Phillippe Stark, should start from that model if they want to make something truly innovative and practical for a wide range of riders as to age and ability (or disability).
