Men perform physically dangerous work far more frequently than women.

Riding a bike in a large city is dangerous - I've never done in it New York, but in London altercations between bikes, pedestrians, taxis and buses are quite frequent. There are few real continental-Europe-style bike lanes.

Perhaps same gender differences in appetite for risk also affects one's decision to ride a bike in a large city?

Last summer, in NYC, I was in central park almost every weekend. After I started counting, I counted like eight low-impact bicycle accidents involving twenty-something girls before it started getting cold in September (it averaged to nearly once a week). I'm going to estimate that prior to counting it was about three or four (it had to be more than two), before it struck me that it was getting repetitive. Once I started paying attention, I was kind of surprised at how frequent and consistent it was. None of them drew blood or broke bones or anything, but the ones that I noticed were usually accompanied by a surprised yell, and enough to make people stop and check for concussions. As far as I witnessed, I did not see any similar accidents involving males in their 20's, or adult women of other age groups. On the other hand, lots of 40 and 50 something women are always out riding bikes with their kids and husbands.

Bicycles in NYC are serious business though. I've known people who were slapped with hundreds of dollars in violations and summonses in one sitting. I know one guy who was car-doored on a narrow street and woke up hospitalized and missing teeth. I've also heard similar stories of males and females drunk bicycling home at night that also ended in serious hospital visits.

More often than not, males in their 20's are on skateboards, and certainly falling a lot, but usually with a degree of anticipation and a strategy for absorbing and surviving the fall. Otherwise, males under 40 and not on skateboards seem to be keenly aware of their own lack of athletic inclination and poorly trained physical coordination (myself included; I like my teeth).

I see a fair number of women riding bikes in Washington, DC. I couldn't tell you the proportion of female to male riders. Our traffic is not as bad as in New York or London, but riders do get hit.
