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.[1]
Apart from being a memorial, it is usually intended as a reminder to passing motorists to share the road. 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.
