Noise producing device

A noise-producing device comprising a body having means for mounting the body to a frame member of a bicycle, a card holder for securing a resiliently flexible card-like member (“card”) to the body such that the card extends freely outwardly from the body, and a resonant chamber in the body for amplifying the sound produced by the intermittent interaction of the free end of the card with a bicycle wheel, and further including a hollow component removably mountable on the body with its interior in communication with the resonant chamber for further amplifying the sound produced by the card, and wherein the means for mounting the body to a frame member of a bicycle comprises an open channel extending into the body in which a frame member can be received.
