The Philly Naked Bike Ride in Philadelphia promotes positive body image.
Hundreds of Philadelphia bicyclists have been caught with their pants down as they saddled up for the annual Philly Naked Bike Ride.
Organisers say about 3,000 riders pedal the 16 kilometre course around the City of Brotherly Love past sights including the Liberty Bell and Independence Hall.
Some riders wear their birthday suits while others sport underwear or just body paint and glitter.
The ride is to promote positive body image, advocate for the safety of cyclists and protest dependence on fossil fuels.
