THE WORLD'S LOUDEST CYCLE HORN

According to ROSPA, 57% of cycle accidents occur because the "driver failed to look properly".

Frequently Asked Questions

The Hornit dB140 is 140 decibels making it the world’s loudest horn.

We have upgraded the electronics and some of the components from the old version as well as completely changing the mount system to a Garmin style mount. The internal upgrades are designed to improve performance while the Garmin style mount makes the dB140 rock solid on the bars, easy to remove and interchangeable with other Garmin compatible devices.

Our dB140 is not waterproof, however it is weather resistant and is tested to work even in torrential rain . The IP rating is IP44 meaning that it is counted as splash proof.

The Garmin style mounts are compatible with virtually every diameter of round bar (22-26mm) and 31.8mm road bike handlebars with our 2 included brackets. Unfortunately, if you have flat aero bars then the mounts will not work. They must be round.

    Best in class

    I love this horn... I've had many alternatives but none compare to the shrill sharp sound of this one and it usually gets through headphones and earbuds which normal bells etc just fail to alert .. this one is to replace my first that just stopped working but the beauty is its just a clean swap and I'm back in business

    Useful Tool

    I don’t have to use it often, only when it matters. Alerts other road users really well. Would buy again.
