It looks nice.
The basic problem, in my opinion, is that single speed bikes are being pursued for their appearance, their apparently simplicity of design and their aesthetic, not for their function. After the build and after the very short honeymoon (one hill long) most riders realize that functionality is more important than style.
Now, the thought line I was pursuing the other day was that you get the multi-gear functionality AND the simple, clean aesthetics of a single speed by putting an internally geared rear hub on your bike.
Dah ting is dis, you gotz to haz brakz on dah cycle! And a gear changing cable, too, for an IGH.
