Loud Bicycle horns are loud.

We harness the sound power of a car horn in a package fit for a bicycle. Both of our Loud Bicycle horn models honk at 125 decibels. Every honk contains two distinct and individually-tuned tones.

Our battery life can't be beat.

Loud Bicycle has a fully-rechargeable battery that can last over three months on a single charge, and can plug into any USB port.

Durable. Weatherproof. Water-resistant.

Loud Bicycle horns are for use in all weather, including rain, snow and cold down to 20ºF (-6ºC).

Loud Bicycle is made in the USA.

Our horns are designed in Boston, Massachusetts and manufactured in New Hampshire.

How does it work?

Honking with your thumb is easy and won't interfere with braking. The button attaches easily to either handlebar and the wire plugs into the bottom of the case.

Loud Mini


The Loud Mini is our newest horn. We took trusted components from our Loud Classic, and fit them into an elegant shell nearly half the weight of our Classic, with a USB-rechargeable battery that lasts twice as long – 4 months (480 seconds of honking). The Loud Mini mounts with an easy release mechanism, allowing you to use one horn on several bikes.
