Although this bike horn is a LOT of fun, it's definitely not a toy. Designed to provide an easily-noticed honk with minimal effort and built to last. Installation takes just a minute or two on virtually any bike or trike handlebars (to help protect bike finish and provide more secure fit, wrap mounting area with vinyl tape or rubber strip.)
