Hornit dB140 Bike Horn | Loudest Bicycle Horn | Adult Electric Bike Bell | V3 |

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!

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.

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.

Best value for the money it's very very loud easy two put on I got this for my mobility scooter it's the best money I have spent on a horn

Amazing performance on this item good quick delivery.

Bought in Jan 2024, was great initially and great product concept. However, it has gradually worked less and less well until now not working at all. Not great for a safety-focused product you need to rely on in London traffic! Not sure if it's the activating button that no longer works or the horn itself. Going to have to buy another horn (since > 1 year), try it, and if it's no good. If it's the button, I'm not sure I can be bothered to undo the neat tape wrapping I've done to hide the wire from the horn to the button.

Good quality, easy to fit, looks stylish, loud you definitely get noticed a quick press to tell people you are there.

Nice product loud and clear and looks great fits well and great value for money
