Lightweight and easy to install, it’s designed for urban commuters and cycling enthusiasts seeking reliable, attention-grabbing safety in a sleek package. ## Description Product description Review: I've never been disappointed with a ROCKBROS product - 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. Review: Fits and bike and is LOUD with 3 different sounds - So easy to put in any bike with any size bar and LOUD! We used them for our NYC rides and loved them. People heard us coming and we passed more safely. Plus was how they fit any bike ## Features - 90dB BELL: It's enough to alert someone that a bike is coming, can be used in daily commuting. 3 different ringtones available, long press for 3-5 seconds to switch.(Tips: Please replace lossy battery to obtain better effect if after a long time of transportation and storage.) - EASY INSTALLATION: Easy to secure and remove, no tools needed, silicone cover is high-elastic so that to adjust different diameters, fits for most bike handlebars. - SILICONE COVER: This bike bell cover is made of with soft silicone material, which will not damage the bike paint, the water-resistant and dustproof design greatly extends the service life. - SMALL SIZE: Small and portable, weight only 51g, suitable for road bikes, mountain bikes, kids bikes, city bikes or other types.
