A ghost bike (also referred to as a ghostcycle or WhiteCycle) is a bicycle roadside memorial, placed where a cyclist has been killed or severely injured, usually by the driver of a motor vehicle.
Ghost bikes are usually junk bicycles painted white, sometimes with a placard attached, and locked to a suitable object close to the scene of the accident.
[2] The ghost bike idea in the United States may have originated with a project by San Francisco artist Jo Slota, begun in April 2002.
[5] After observing a motorist strike a bicyclist in a bike lane on Holly Hills Boulevard, Patrick Van Der Tuin placed a white-painted bicycle on the spot with a hand-painted sign reading "Cyclist Struck Here".
A bike memorial project[15] was started in Durham, North Carolina, in 2013 to commemorate the death of two prominent cyclist[16] and bicycle safety advocates.
