The BioLogic Blast Airhorn puts you in the same sonic range as a standard car horn -- and why not?
Sometimes a bell just isn't enough. This airhorn uses compressed air and can be refilled with any regular bicycle pump. No cartridges to buy. One charge will last you up to 50 blasts.
A quick release mount allows easy removal for use off the bike and prevention of theft.
