Women don't play a bunch of sorts of any kind, perhaps with exception of tennis. I'm guessing it's because sports are considered to be fun and women are supposed to be more practical. What's the poon of chucking a ball from a to b or cycling around in circles when you cold be doing something more constructive. Perhaps this is why they don't play video games either.

The only sport I see a predominant black contingent is basketball (see the movie White men can jump). The whites of America and Europe are well settled and have disposable incme to spend on sports equipment. The non-whites, although many are well settled (read: worked hard and are well off) still inherited the mentality of their parents who had to work real hard for their kids future. Which means no time or money should be spent n frivolous activities like cycling for pleasure.
