   Often painted entirely in white and locked to a fixed object as close to the accident site as possible, ghost bikes aim to act as both a memorial –they feature the name of the dead rider and other details, whether on a sign or painted to the frame – and a cautionary reminder for cyclists and drivers about what can happen when bike and vehicle come into contact.
