The World's Loudest Bicycle Horn

This is the loudest bicycle horn in the world that sounds a piercing tone as loud as a jet engine. The patented horn helps keep cyclists safe even when they cannot be seen with an emphatic 140-decibel warning that penetrates a vehicle’s windows and stops self-absorbed pedestrians in their tracks. The horn operates easily via a remote trigger so there's no need to lift your hand from the handlebar to give distracted drivers or headphone-wearing smartphone users a humongous heads-up. The horn can be switched from a lower-frequency tone that sounds like a car horn for street riding to an oscillating high-pitched chirp recommended for trail riding. Its IP44 splash resistance assures reliable use in rainy conditions. Two included AAA batteries power the horn for 6-12 months and the included mounting bracket fits most bicycle handlebars. 4" L x 2" W x 2 3/4" H. (5 oz.)
