I love this fun reinterpretation of the classic bike horn. Lots of fun possibilities for custom sounds or voices. The Horn Bike is an Eco-friendly silicone bicycle amplifier, features an adjustable strap to fit all bicycles and can be set in almost any angle.
“Using the principle of the bugle, concentrating the voice and direct the conduction direction in order to reach the effect of increasing the volume, it can increase 13 db after use and does not need any supplementary electricity, it is absolutely environmental friendly.”
There are a number of different products which I think are pretty great as well including the horn stand and phone cell.
