People's Bike Library of Portland

People's Bike Library of Portland, also known as Zoobomb Pyle or simply "the pile", is a 2009 steel and gold leaf sculpture by local artists Brian Borrello and Rankin Renwick, located in Portland, Oregon, in the United States. It was erected in collaboration with the Zoobomb bicycling collective, and serves as a bicycle parking rack, a "lending library" for weekly bike riders, and a monument to the city's bike culture. The sculpture features a two-story spiral pillar with a gold-plated small bicycle on top; bicycles intended for Zoobomb riders are locked to the pillar and base, which has metal loops serving as hooks.
