Ustris Electric Bike Horn 100-120 DB Electronic Bicycle Bell Waterproof with 4 Sound Modes and Rechargeable Battery for Teenager Adults Mountain Bike/Adjustable

This is a very nice and loud bike horn, I made the mistake of trying it in the house and almost went deaf. it has a switch with two buttons, one button to cycle your tone selection second button to use what tone you selected last/prefer to use without the (tone selection option). essentially being your "favorite horn". I found 2 tones out of the bunch rather loud and useful , I personally didn't care for the other tones as they didn't seem as loud to me. it will definitely get peoples attention weather in car or on the bike path.

Love the way it's loud, loud enough that even a extreme deaf person can hear it ! I scared the crap out of two people the other day ! I bought it for my power wheelchair, because the built in horn on it isn't loud enough !

I just received this bike horn today and it is great. I hated the wimpy horn that came on my E -bike. You had to be right next to someone for them to hear it and I doubt if anyone in a car would hear it. This horn is loud and it sounds like a car horn.

Works great impressively loud

Love the horn, sounds great, battery life is great and a breeze to install.

very loud horn, just wrap rubbrr attachment cord around handle bars and off you go

I like the size, sound, and fit of the horn

Works pretty good. I don't know how long the battery lasts yet. Very easy mounting with just the two straps and they seem to hold very well. I don't think it's a full 120 dB I measured around 95 but that's still plenty loud.

its great wish it had more color options

Mixed Review here. The horn is easy to install, I like that it is rechargeable, and that it is reasonably loud. What I do not like is its not very pleasant to use. I ride on some mixed use trails in the city, where I am often rolling up behind people walking or jogging. I would like a kind of friendly sounding beep, this horn is kind of off-putting. Since buying this, I also ordered a mechanical old school bell, which I think will be more appropriate. I want to chime my presence, not blast people out of my way. Most people I'm encountering are gracious and friendly when they know I'm behind them. The rest are wearing earphones and don't speak English, so a polite "Passing on the Left" isn't really working. We'll try the rocket launchers and the cow catcher next. Stay Tuned!
