The ROCKBROS EH-2 is a compact electric bicycle horn designed to keep you safe and noticed on the road. It produces a loud 120 dB sound through a trumpet-shaped design, ensuring that drivers and pedestrians can hear you clearly even in noisy urban environments. Constructed from a blend of ABS and PC, the device weighs only 34 g, making it a lightweight addition to your handlebars. It is powered by two replaceable CR2032 batteries and features an IPX4 rating, which means it can handle light rain and splashes during your ride. You can easily attach it to road bikes, mountain bikes, scooters, or children's bicycles using the included elastic rubber straps. The simple single-click activation allows you to alert others instantly without taking your focus off the path ahead.
