My city commuter is a single speed. I went from 50T-17T to a 50-19T but any change in the gearing and I'd need a larger chain honestly...
It's hard to train hams at city flats with platform pedals. If you want to train them on a bike, steep hill (8-10%) repeats do wonders.
Depending on your riding styles and the distance of your ride, certain muscle masses could work against you. For example, I rarely see good climbers with large quads. Even if they do, most likely they won't last in long climbs. Almost all of the good looking muscles gained from artificial body building are useless in cycling.
