A peaceful, imaginative and fun protest against oil dependency and car culture. A celebration of the bicycle and also a celebration of the power and individuality of the human body. A symbol of the vulnerability of the cyclist in traffic. The world's biggest naked protest: 50+ cities and thousands of riders participate worldwide, including more than 1500 in the UK in 2007

This year, rides take place across the UK between June 6th and 14th, and we expect several thousand riders. Sign-up on the main page or click on the city names above for more details.
