The Bike Horn iHorn is made from a vintage bicycle bulb horn. The bicycle bell was invented by John Richard Dedicoat,and patents for bicycle bells appear as early as 1877. A "bulb horn" is operated by squeezing a rubber bulb attached to a metal horn, producing a single note through a metal reed. In some places, bicycle horns are required equipment. In the Summer of 2012, NYPD set up bicycle equipment checkpoints, pulling over cyclists and ticketing them for missing safety equipment, including horns or bells. One can only assume that a The Bike Horn iHorn would meet those safety requirements, while providing hours of listening enjoyment without the pain and annoyance of ear buds. So ride into the sunset with The Bike Horn iHorn.
