Dozens of cheeky bike riders startled pedestrians and drivers in one of the Capital's busiest tourist spots Saturday as they rode their bikes naked to "expose" the issue of oil dependency.

About 75 cyclists rode through the ByWard Market as part of the annual World Naked Bike Rides that are held across Canada and 20 other countries.

The nude cyclists were protesting oil dependency, as well as the danger they feel riding their bikes on busy city streets.

Many spectators used their cell phones to photograph and video the event. Although there were many raised eyebrows, many people seemed to see the humour in the bike riders in the buff.

Most riders were careful to wear their helmets.
