Abstract
An amusement device for a bicycle wheel is disclosed. According to the present invention, the amusement device comprises a whistle, and a means for attaching the whistle to the wheel such that when the wheel rotates, wind passes through the whistle and produces a sound audible to a human ear. The present whistle 10 is a reversible whistle because it will produce a noise when air flows into the whistle from two different directions. The present invention is a double whistle because it funnels air from one direction into two separate whistle elements. The whistle 10 is also a double reversible whistle 10 because it can funnel air into two different whistle elements with air flowing in two different directions.
