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 Bicycle horns are for use in all weather, rain, snow and cold down to 20F (-6C).
Loud Mini

The Loud Mini is our newest horn. We took trusted components from Loud Classic, and we fit them into an elegant shell that is nearly half the weight of the original Loud Classic – and it is still just as loud and still sounds just like a car.
The USB-rechargeable battery lasts 4 months (480 seconds of honking); that’s twice as long as the Loud Classic.

The Loud Mini fits all handlebars, and with an easy release mechanism, you can use one horn on several bikes. The Loud Mini is water resistant and can be used all day and night, in rain and snow.

Loud Accessories
Our horns come with everything you need: The horn itself, a button with a 2.5 ft. button cable, a mini USB charging cable, and a way to mount the horn to a bike.
Here are a few extras you can add on.

Anti-theft bolts
Leave your Loud Bicycle horn securely on your bike with special anti-theft bolts. These come with the special tool needed to install and remove the bolts.
You will receive the standard bolts in addition to the anti-theft bolts.

Wall charging block
A standard Mini USB charger between 0.5A-0.9A or your computer’s USB port will charge your horn.
Get the Loud Bicycle wall charger and don’t worry about any of that.

Button extension cable
The horn button comes with a 2.5 ft. (76cm) cable which fits most bikes.
You can extend the distance from the button to the horn by an additional 2.5 ft. (76cm) with each cable extension.

Extra bike mount
This accessory for the Loud Mini gets you an extra mounting set so you can quickly swap between bikes without removing and reattaching the mount.

Extra button
Each horn comes with a button, but you can also get an extra one. The extra button works with the Loud Mini and the Loud Classic horns.
