>weightUnless your city sports San Fransisco-tier hills everywhere, not relevant either. And the lack of gears would also cripple a fixie bike in such an environment as well.
A sportier bike would make sense if you live in an area with considerable suburban/urban sprawl, in which case you are disadvantaged against cars. In a built-up, very dense area, your main advantages are not raw speed: it's your ability to squeeze through places and get off the line quicker than cars which have to deal with restrictions that you don't.
In any case, I'm not pushing for a Dutch bike with IGH, enclosed chain, and a 50 lb steel frame. All I'm saying is that there are advantages to step-through bikes in an urban setting, primarily related to ease of use. There are bikes out there which have similar geometry for 2/3 the weight.
