Electric Bike Bell

And this one is no exception. It's all about the design. Having one button matters. My previous horn had 3 buttons and the one to sound the horn was in the middle. It was hard to hit reliably without looking as is the case 90% of the time. This ROCKBROS horn is great that way, there's only one button and can be found fast by feel. The next great design feature is the whistle sound. It sounds like a police whistle and gets the attention of drivers. This unit is not as loud as my previous horn but it is adequate. Don't expect this to stay put on the handlebars with only the rubber strap. In my experience, no rubber strap you can pull tight without breaking is strong enough to hold the horn in place when you sound the alarm. Fortunately, this unit rests against my brake lever at an acceptable angle. YMMV. About the lack of rechargable battery, I have come around to it. I think this design holds up to the weather better; especially when transported at highway speeds on a rack. I think that was a factor in the demise of my previous horn.

Gave to my brother. He liked it, but he told the horn isn't that loud.

Easy to install and nice and loud. My daughter likes the multiple tones.

Just received this item, and had to order a replacement. Pressing the button to activate did absolutely nothing. It was DOA! I can see what some complained about regarding charging. There is NO charging port, and apparently no way to change the battery. Apparently this is a self-contained unit and when the battery dies, it is just dead and you have to purchase a replacement. Cannot say that I am happy about that and most likely would not purchase again, due to this. I also would hesitate to recommend the item for purchase, as you do not know how 'fresh' the battery is in it. Your usage period would be totally determined by how fresh the battery was, when you received it. You are essentially rolling the dice here. -------------------------------------------------------------------------------------------------------------------------- UPDATE: In the initial review, above, you pretty much get my initial reaction to this item. I then started looking closely at the item, finding that I could pull back the rubber covering from the item. Well, I kept pulling, to see what was underneath the covering. I found a 'battery tab', where you have to pull a covering item, which had been placed to prevent the battery from making contact and draining. I pulled the covering out, and tried the whistle, now that the battery was making contact. The horn worked!! BTW, there is a battery 'tray', so you CAN replace the battery, when needed. Without instructions it just was not obvious as to what was happening. I imagine others have also returned the item, thinking it did not work, due to the battery being prevented from being operational, until you removed the material preventing the battery from making contact. The replacement that I requested has already been shipped, so I could not cancel it. I will just keep both of them, and just have a spare. I would now give the item a FIVE STAR rating.

This is a good bike horn. It's compact, easy to use, mounts on a wide variety of bars. I found it to work reliably while it lasted. I have one other like it without the Rock Bros label. I'm only giving three stars due to uncertain durability. After about 8 months I needed a battery replacement. Unfortunately when I went to replace them, the horn would no longer work and I threw the horn away. I should have contacted the company but I did not because at the time it was only ten bucks. As mentioned I also have a no name device that looks just like it but without logo. I have replace those batteries once or twice in more than two years and it still works fine. I've tried other devices but they are bigger, clunkier,obnoxious, and quirky. So I'm giving this type another try but if I have a problem again I will contact the company since the price has risen by 40%. If I could give 3 and a half stars I would. As I said it's just a question of durability.

This is great for road cycling, especially when you are dealing with traffic. Very loud horn!

Using this on my electric bike; works great for alerting others on park paths, etc. Easily installed, good value for the money

Not loud enough. It’s a cute little bell and has three different sounds, and a great easy to push button. Attaching it to the bike is also easy. The biggest drawback is it runs on 2 small batteries which are too small to create a loud enough sound to be heard more than 5 feet away.

Everything is good except its silicon strap to tie with cycle steering, instead of silicon it should be of metal , aluminium for longer life, Silicon. Straps breaks due to heat , reuse again and again

Important for rider in park loud sound too

Tinham enviado apenas um. Reclamei. Mandaram o outro. Tudo 100%. Não se compara com um apito, mas chama a atenção das pessoas. Dos carros é impossível ouvir.

I purchased two of these… one worked… the other did not. The one that worked though always moves and is not right against the handle bars. Not very loud either. I’m returning them both.Arrived BROKEN...DO NOT BUY!!!!! They are JUNK! and no communication from the seller. THAT should tell you something!

Sound is low
