Quiet protests for bicycle safety, Ghost Bikes are somber reminders of the inadequacy of urban cycling infrastructure. The simple memorials, bicycles painted white, often festooned with flowers, commemorate bicyclists killed by motorists. The bikes are typically chained near the location of the accident and accompanied by a plaque with the name, age, and sometimes photo of the victim, as well as the date of the accident. The first Ghost Bikes were created in St. Louis, Missouri, in 2003, and have since appeared in over 150 locations around the world. The NYC Street Memorial Project set up GhostBikes.org to document the memorials, which serve not only as markers of loss but as vivid reminders to motorists and cyclists alike of dangerous traffic conditions.
