THE WORLD'S LOUDEST CYCLE HORN

140 decibels is the equivalent sound of a jet engine and 4 times louder than the nearest competitor. You can alert cars, buses, lorry drivers & pedestrians to your presence. It has two sounds - a piercing 'road' mode (140dB) and a lower pitched car horn sound (121dB) for cycle paths. The remote trigger means it is safe and easy to use when braking, while being easy to install and remove thanks to the Garmin style mount, the dB140 fits all bikes. Completely weatherproof (although not submersible), the dB140 is a potentially life-saving accessory when riding in towns and cities.

Two Garmin Style Mounts Included

To ensure a perfect fit with all handlebar sizes two mounts are included - one mount for bars with a diameter of 22-26mm with 4 differently sized spacers and a second dedicated 31.8mm diameter bars (road bikes). You can use your spare mount on a different bike so you can easily swap the dB140 from one bike to another.

Impressive performance

Featuring two horn modes; 140dB and 121dB respectively, the dB140 requires uses 2 x AAA batteries which last for up to 12 months of normal use (6x 1 second blasts per day). The dB140 makes riding in town safer and less stressful: no need to shout, no need to swerve, no more emergency braking.

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.

    attention getting

    It saves me from having to use my voice to get people's attention, which was giving me a hoarse voice. I was in a bad accident one year ago, so I have become extra concerned about avoiding another accident. This seems to be very helpful in that regard. I use it very frequently, anytime I feel that I am in a situation that seems at all sketchy, I sound the horn just to make sure that people are aware of my presence. I was in a bike lane and a bus drifted into the lane, I laid on the horn and the bus miraculously drifted out of the bike lane. I previously tried using a whistle, but this is much better and easier.

    Sound

    I like the volume of the horn. I wish it sounded more like a horn than the squeech that comes out. I have read that you can change the sound. There is no instructions how to do this if it is possible. It would attract more attention if it sounded more like a horn. People do not understand what is going on.

    Looks Good

    From the advertising blurb I thought it might be too loud but it’s not, in fact it’s a little the other way. The note is fairly shrill, it needs a little more power in lower frequencies as against ‘loudness’ but I guess that might require lots of battery power. Mine did not work at first, I had to change the batteries for something more mainstream, Energizer Industrial did the trick. Sometimes the battery compartment shape, designed to prevent the wrong polarity, just stops the batteries making contact.

    Really like this horn. Both settings are loud enough to get the attention of people and vehicles around me when necessary.
