Artists, builders, assemblers, and aficionados of the wild and wacky are busily preparing for the 4th Annual Papio Kinetic Sculpture and Art Bike Parade which takes place in Key West on Saturday, May 4 at 5 pm.

Spearheaded by Key West’s Art & Historical Society, the parade includes colorful sculptural floats, tricycles with exotically costumed riders, fantastically decorated bicycles and other moving works of art — all powered by human effort alone.

The weekend-long event, which kicks off on Friday, May 3 and runs through Sunday, May 5, honors Key Largo’s “renegade artist,” the late Stanley Papio, who created whimsical sculptures out of discarded car parts, appliances, and other objects.

The parade, accompanied by a Grand Marshal and marching band, starts at the Custom House Museum on Front Street, winds its way over to Duval Street and wraps up with a post-parade party and live concert at the Key West Amphitheater.

But the end of the parade doesn’t mean the end of the art-filled week-end. Floats and other parade creations will be moved to Fort East Martello Museum, where a special display will be staged until 7 pm on Saturday and from 9:30 am to 4:30 pm on Sunday.
