A bicycle safety device indicates not only the presence of a bicycle but the minimum distance that should be maintained by other vehicles in passing the bicycle. The safety device includes a support member that mounts to the bicycle frame immediately below the bicycle seat on the seat elevation-adjustment-bolt and extends parallel with the side of the bicycle frame and forms a right angle at the end. The parallel member includes reflector means on both of it's sides and an indicating member attached to said parallel support member and extends outwardly horizontal from the side of the bicycle frame a predetermined distance. Said horizontal member may be shaped into two or more arrows to create an illusion of a moving arrow and may be built out of reflector-type sheet metal, and will protect the bicyclist from all four directions, namely, north, south, east and west, because both of said members comprise reflector means on both of the sides.
