People all over the world ride their bikes to draw attention to different issues, from the environment to personal freedom. I asked a few of the participants why they were doing it and the most common answer was that it was a fun thing to do.
Riders of all ages, genders, ethnic background share a day on their bikes around London.
As the London organizers put it themselves: The World Naked Bike Ride is a peaceful protest that intends to get its messages across by generating public interest. We like other road users and spectators to be pleasantly surprised and take notice. We do not behave badly!
Personally I think it is a great idea. No reason to hide a human body.
