They went along for the ride. Their clothes did not.

Hundreds of cyclists dressed down for a breezy ride through some of Philadelphia’s main streets Saturday during the 14th Philly Naked Bike Ride.

The eye-catching annual affair began in 2009 and revealed itself as an event to promote body positivity, cycling and fossil fuel reduction.

The event seems to encourage riders to go au natural — and organizers stress there’s no constraints — with participants able to go as “bare as they dare” for the roughly 13-mile journey.

The oftentimes pant-less pilgrimage changes from year to year, but typically takes bikers baring it all on a brisk ride past iconic city landmarks.
