An interesting study looking at the makeup of London cyclists and why some people (and ethnicities) don't cycle. As a side note, there are nearly 2000 comments, and they seem to be largely from insulted white males, which makes a change from the usual 'I nearly got hit by a car/rider yesterday', cyclists running red lights etc. that tends to dominate most comments on cycling articles.
