Interestingly they don't mention helmets and hair as one possible contributor of the gender gap in bicycle ridership (and motorcycles too). Bicycling is an activity where you should be wearing a helmet for safety, and this is at odds with styling your hair in the morning since that helmet with mess up many styles of longer hair. However, that being said, this data comes from city bikesharing services, which often don't involve helmet usage. I also wonder how much clothing choices impact ridership. Unisex clothing choices (pants, shorts) are more convenient for bicycle riding than skirts and dresses. I'm curious, if you normalize the data to discount women who spend a lot of time on their appearance (particularly their hair) and discount the percentage of women who are not wearing unisex clothes, do the numbers more closely hit a 50-50 distribution. Lastly, I'd love to see what data Google has on bicycle ridership for Google Bikes on its Mountain View campus (relative to the ratio of men-to-women at Google of course)
