Hornit dB140 Bike Horn, Upgraded V3 Model, World's Loudest Bicycle Horn for Increased Rider Safety, Remote Trigger and Upgraded Mounting System Included

I'm a daily bike commuter and I've had this for 3 years. It's still working and I haven't even needed to change the batteries yet. It is loud enough to get the attention of drivers with their windows up which is really important. Little metal bells don't cut it with drivers. It has a simple, single-button interface. No switches or apps. I like that a quick tap makes a slightly less loud chirp for warning pedestrians and other bikers, otherwise I just lay on the horn to make sure that cars know I'm there. This is a must if you are sharing the road with cars.

I shopped around for WEEKS and I'm happy I bought this one. Cycling is my main source of commuting, whether for work, fun, or exercise. I live in midtown Manhattan and cycling here is a sport only for the brave or the idiotic. Bike horns (not bells) have saved my life multiple times. When my old horn fell apart (and so did its replacement...), I searched for a new one that met all my requirements. The only thing that worried me about this horn was the fact that it used standard alkaline batteries instead of being USB-rechargeable. I took a risk because it's very hard to find a product that is as loud as this one claims to be, without a bunch of extra nonsense. (I don't want a motion detector alarm! I don't want a remote control! I don't need an LED screen!) I've been using this for about a month and a half now, and have not had to replace the batteries. And trust me, I use this a LOT. I wish there were different noise settings. My old one had five different sounds you could cycle through (no pun intended). But this horn still gives you the option of a quick push (a little chirp) or a hold (piercing siren). The handlebar "remote" is very convenient and easy in an emergency traffic situation. The horn (which sounds more like a siren) is VERY loud. I don't know how to measure or estimate decibel levels, but I know this is loud as hell. This has truly saved me from some potentially horrendous accidents with drivers who do not pay attention to cyclists. I haven't really tested the waterproofness but the light exposure to rain has been fine. THIS IS THE ONE YOU WANT

Overall, a good horn. It is nice and loud. The brackets aren't the best fit, but I made it work. Can't spell of the battery life as I only had it for a month.

Very loud noise maker. Easy installation. Activation button slips a little on the handle bar with a clumsy installation around the brake and shifting handles, but there are solutions for that problem. I use a grocery store vegetable bag and rubber band around the handle bar to solve the moisture problem. I do not like the idea of twisting the horn off the mount every time I leave the bike outside. It is the best device that I have found for getting the attention of oblivious, selfish morons. However, it is not a cure all, some people you can not do anything about, so be prepared. I would estimate the horn gets reactions 80% of the time, much better than without the horn. The horn user should consider courtesy by giving long distance initial warnings, it is loud and startling. Not stolen as of this review date!

Excellent horn! The remote trigger is a nice touch. Used it several times today. My scooter is turning into a beast!

Loud but sounds like an alarm more than a horn. Wish it had more than one sound, especially for the price.

There are two settings. One that sounds like a regular bike horn and one that sounds like an emergency vehicle behind. You is very loud and very high-pitched and will definitely get people‘s attention.

The horn worked well while it worked. it was simple to install, simple to operate and loud enough for my purposes. That said while the product is advertised as WEATHERPROOF it really isn't. And they kind of tell you that, if you're willing to google IP44 which they do tell you the product is. the problem is that if you go look up what IP44 means nobody in their right mind would then call that "WEATHERPROOF" ... because unless you live in the Sahara, weatherproof probably means "you can ride your bike in a downpour and not expect you'll destroy your horn" Personally I find it unacceptable for a company to sell a product that is meant for a bicycle or motorcyle that cannot withstand a downpour or 10.

Un espectáculo te salva la vida se escucha muy fuerte los coches paran y dan paso en las rotondas aun que sean con ventanas subidas. Lo recomiendo muchisimo esta hecho de materiales de calidad se puede montar y quitar fácilmente. Eso si si no lo montes permenente en el manillar la probabilidad que te lo rroban es muy alta asi que no hay que olvidar quitarla cuando guardes la bici en la calle

Bello rumoroso si spostano tutti

Je n'ai pas eu de difficulté à l'installer. Le mode d'emploi était clair d'en mes souvenir. Après plusieurs mois d'usage, rien à signaler d'alarmant. Dommage que qu'on ne peut pas gérer le volume car c'est vraiment fort fort bruyant même pour le cycliste.

Really great horn! Genuinely loud. 2 modes. I would say this is a necessity for safety while cycling. Not too difficult to install. Recommended 👍🏻
