Charge Bikes have a new girls bike in their 2010 / 2011 line called the Hob. It's a pretty ground braking bike for women as it's a single speed bike which can be ridden either fixed or as a free wheel - but it's drop bar and sweep handle bars allow a relaxed sitting position - somewhere between riding a racer and a dutch bike.
Whats also interesting about this bike is the Mixte frame - where the top tube is replaced with two smaller tubes that run all the way to the rear axle. I saw quite a few Mixte's when I was in the US but you don't see too many over here. They have a functional elegance that I rather like.
