The naked bike rides have taken place. You can find a lot of videos on line – try Vimeo and Dailymotion, as YouTube is not a good place to find naked people.
Here is one of the best videos of this year’s London ride.
As a bike rider, I’m a coward. I used a bike daily in the Netherlands, where cyclists mostly have their own routes, but one ride on my return to England decided me, and the bike has not been out of the garage since 1998. Perhaps I should get it cleaned and restored, and take it to one of next year’s rides.
