World naked bike ride
annual protest
World naked bike ride is a form of protest. People organize a bike ride, where most of them are naked, or nearly naked, usually in summer. The first bike ride was done in Zaragoza, in Spain, in 2001.[1] The biggest event nowadays is in London. The participants want to give a vision of a "cleaner, safer, body-positive world". They do this using a clothing-optional bike ride.
