Review: THAT IS LOUD! Loved it - THAT IS LOUD! If you're a commuter, it could save lives! Batter lasts long, easy to install on the bike and it fits a big variety of handlebars, the button works fine, it really alerts people and cars, very loud, the loudest I ever had considering the battery and size. Really recommend it.
Review: Very loud, very good - I have had this for a couple of months now, riding on everything from urban residential roads, to cycle ways and bridle paths. It is an excellent product, very loud (in both sound modes) and seems more than adequate to get the message across to both pedestrians and all other road users. In addition, it's worth noting that the switch (which you put on the handlebar or grip) is easy to use while wearing gloves, something that has been a problem for me with other more conventional bell designs. If you get one of these, put the batteries in and take it outside before testing... you might be surprised how loud it is in your front room!

## Features

- THE WORLD’S LOUDEST CYCLE HORN. 140dB at source the dB140 puts you in control of your safety because it gives you a way to make people know you’re there even when they aren’t looking.
- TWO HORN MODES. “piercing mode” is a high-pitched 140db duo tone, primarily for road use, designed to be heard by car, van and truck drivers as well as pedestrians with headphones. “horn mode” is a 121dB car horn style sound designed to be used to warn pedestrians in parks and on trails.
- 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 to 31.8mm diameter bars (road bikes).
- ENJOY THE RIDE. the dB140 gives you the ability to let other road users know you’re coming and that alone makes cycling much less stressful. No more shouting, fewer emergency stops, and more time spent enjoying the ride.

## Questions & Answers

**Q: I'm buying this for a friend of mine who lives in NYC.  I'm worried it will be stolen off his bike though... is this easily removed and stolen?**
A: Yes, you have to remove it a half turn to pull it off to install batteries unplug the button rotated, 180° and stick it in your pocket unless that person gets mugged it won’t get stolen

**Q: Is it possible to get a longer cord? I want to mount it on my seat post facing backwards so I can alert cars coming up behind me.**
A: No idea why Maurice Pinder would take the time to provide you with false information.

“DB140 EXTRA LONG TRIGGER 150CM (5FT)” Hornit most certainly makes a longer trigger. You can easily purchase the item.

**Q: Is it easy to replace the batteries while the horn is mounted or does the horn need to be removed to get to battery compartment ?**
A: Yes it is easy to replace the batteries.  To change the batteries, unplug the thumb button wire, then turn the horn body 90 degrees (quick release) and lift off the handlebar bracket. Replace batteries, then reverse the above procedure. Re-Plug the thumb button wire. The horn works very well and load enough for people to hear you coming.

**Q: Unit works fine, but it sounds like there's a loose piece of plastic inside that rattles around when I shake the unit?  Is that normal?**
A: No! It should not sound like a rattle. If you are very concerned ask if you can return it for a replacement. 
Even if you are passed the return deadline, a reasonable company will allow for a replacement.

### ⭐⭐⭐⭐ Good but comes with flaws
*by J***N on 10 March 2024*

A well constructed but not waterproof unit. If any rain gets into the unit it will stop working, the button can be replaced quite cheaply from the HornIt website, but the main unit will set you back another £30 (current Amazon price) to replace if it breaks due to water damage. This is the biggest negative feature. Unit comes with "Garmin like mounts" but the official Garmin mounts are too small for the unit and cannot be used so they are not interchangeable. The brackets supplied don't fit every handlebar size, contrary to claims otherwise. The large bracket cannot be used with the supplied spacers underneath, due to how the spacers and larger bracket are designed, meaning the large bracket fits 32mm handlebars only. The smaller bracket fits 22-26mm handlebars, leaving an incompatibility issue for any handlebars measuring between 27-31mm. Unit is clearly designed for road / gravel / touring bikes not MTB, contrary to claims otherwise, as it will not fit most MTB handlebars and the intended use case of the product is to be loud enough for pedestrians to hear over busy traffic. The hornIt on a MTB trail, despite the advertisement, would be, too loud and too aggressive. On a road bike it takes up a significant amount of room of the handlebar. The louder 140db bird chirp like sound seems to cause confusion, a stop and look confused like a squirrel in headlights, in the majority of pedestrians, possibly because it's a sound which is very unfamiliar on the road, but the quieter, still loud enough for busy road use, horn sound most pedestrians respond well to, in the same way as they do to a car horn sound. Everyone knows what a horn sound means. Pedestrians with headphones in who walk into the road like zombies still cannot hear it. It is by virtually all measures better than a bell on the handlebars for its intended use and can be heard over rush hour traffic by both pedestrians, other cyclists and from inside cars in most cases.
