Abstract
A noise-producing device comprises a body (12) having a clamp (24) for mounting the body to a frame member of a bicycle or other motorless vehicle with spoked wheels. The device includes a card holder (15) for securing a resiliently flexible card (14) to the body such hat the card extends freely outwardly from the body. A resonant chamber (18) in the body amplifies the sound produced by the intermittent interaction of the free end of the card with the spokes of the bicycle wheel.
