The ROCKBROS 340006 is a compact bicycle bell designed specifically for children, featuring a minimalist round shape with a playful print in blue. It produces a clear alert sound ranging from 80dB to 100dB, which helps young riders be heard by pedestrians and other cyclists during their trips. Constructed from a combination of iron and PVC, the bell weighs approximately 58g, ensuring it doesn't add unnecessary bulk to the handlebars. It fits standard 22mm diameter bars, making it compatible with a wide variety of rides, including city bikes, folding bikes, electric scooters, and MTBs. To make the setup simple, an Allen key is included in the package for a secure installation.
