It may be the only bike event all year where participants don't need to suit up.
Saturday marks the tenth anniversary of the World Naked Bike Ride in Chicago, a worldwide event that celebrates bikes, the human form and makes a statement against Big Oil.
The World Naked Bike ride is "a people-powered happening bringing radical attention against oil addiction; It's not primarily a naturist party," the event's website reads.
According to the World Naked Bike Ride website, at least 70 cities and more than 20 countries participate in annual people-powered event.
This year, skaters on both boards and quads are invited to join in the 14-mile trek around town, with at least one demonstration stop planned for a Lincoln Park BP gas station.
With a bare-as-you-date motto, the yearly event encourages riders to "obey police and thank them for their help," according to the WNBR Chicago page. While indecent exposure charges are possible, nudity-based arrests are generally rare.
For Chicago's ride, swimwear and costumes are acceptable gear for those who don't wish to bare all; a body painting party also kicks off at 6 p.m. for those who want something in the way of coverage but don't want to violate the spirit of nudity.
The 10th annual World Naked Bike Ride Chicago is Sat. June 8 from 8 p.m. to 11 p.m. Check-in starts at 6 p.m. at 1025 W Randolph St.
