Bike Horn,120dB Bicycle Bells IPX4 Waterproof Bike Bell with 300mAh Battery Operated Electric Horn for Mountain/Road Bike/Scooters Adult and Kids

Perfect volume..:)

Very loud! Tested it in the house and it was like an airhorn. Definitely will get attention of anyone outside.

Got this for my son's ebike. Super easy to install and works well.

EXTREMELY loud, perfectly stable and hasn’t broken, only problem is you can’t spam the button.

Horn is great but it is not water proof!!!! Rusted the battery area and the sound was very low to no good. I could not replace the batteries due to the rusted terminals.

I was looking for a horn I could use on my power wheelchair. People seem to have their heads in the phones these days, not watching where they are walking. I've had people walk straight into my wheelchair or right across my path. Saying "hey" or "excuse me" doesn't seem to work much. When it does, they always say, "I didn't see you." Of course they didn't, because they weren't paying attention. (I'm surprised there aren't more accidents where people with their faces glued to their phones walk into open manholes or walk into moving traffic.) This horn does the trick. It is loud enough to get them to look up from their phone. It also gets people to get out of the way, instead of standing transfixed by the oncoming wheelchair like a deer in headlights. I wish it had a mode where it played an "ah-oo-gah" sound. That would be a little gentler and more humorous than the current strident "wake up, you blunderbuss" sound it currently plays.

Working well

“Esta bocina de bicicleta es súper potente, realmente se escucha fuerte y ayuda mucho a hacerse notar en la calle, lo cual da más seguridad al manejar. El sonido es claro y alcanza buena distancia. El hecho de que sea recargable con batería de larga duración (hasta 30 días) es un gran plus, y además es fácil de instalar y quitar. También me gustó que sea impermeable, lo cual la hace ideal para usar en cualquier clima. En general, es un accesorio muy útil y confiable para ciclistas que buscan seguridad y practicidad. ¡La recomiendo totalmente!”
