If you saw a nude cyclist over the weekend, it probably wasn't someone who forgot to do their laundry. Each year, bikers all across the globe participate in the World Naked Bike Ride, a clothing-optional event that seeks to draw attention to cyclist rights and promote positive body image. It's also a showcase of some impressive Chicago tattoos. Take a look at our (probably NSFW) photos from the Chicago ride and thank these brave folks for keeping our city's bike shops in business.
