Loud Classic has the power and sound of a car horn and mounts on a bicycle. The Loud Classic horn marks the first generation of Loud Bicycle products. With our signature dual-tone sound and a blaring 125dB to support it, the Loud Classic hosts our signature Loud Bicycle sound. While heavier than the Loud Mini it is lighter than a U-lock. It can attach to the top tube, down tube or stem with 4 hex screws.
