Hundreds of men and women have been spotted wearing nothing but their birthday suits as they take part in the world n*ked bike ride.
The unclad cyclists took over city centres all over Portland this weekend, parading through the streets in their hundreds.
They were all taking part of the 12th edition of World N*ked Bike Ride which ultimately intends and aims to highlight the vulnerability of riders to traffic on the roads.
Some riders were completely unclad, some were partially clothed and many were covered in body paint for the 8.5 mile ride.
