The ROCKBROS Electric Bike Horn is a compact safety accessory designed to make your presence known on the road with a powerful 120 dB alert. Its trumpet-shaped housing is crafted from a blend of ABS and PC materials, keeping the device lightweight at just 34 g so it won't add unnecessary bulk to your handlebars. Operating with a simple single-click activation, this horn runs on two replaceable CR2032 batteries. An IPX4 rating ensures it remains functional during light rain or splashes, making it a reliable choice for various weather conditions. You can easily secure it to mountain bikes, road bikes, e-bikes, scooters, or children's bicycles using the included elastic rubber and silicone straps.
