The ROCKBROS 340006 is a children's bicycle bell designed to keep young riders safe and audible in traffic. It features a playful character illustration in blue, making it an appealing addition to a child's bike. Constructed from iron and PVC, the bell is lightweight at approximately 58g, ensuring it doesn't add unnecessary bulk to the handlebars. This accessory produces a clear sound ranging from 80dB to 100dB, which helps alert pedestrians and other cyclists. It is compatible with handlebars that have a 22 mm diameter, making it suitable for a wide variety of vehicles including mountain bikes, city bikes, folding bikes, electric bikes, and electric scooters. For a quick setup, an L-shaped Allen key is included in the package to secure the bell firmly in place.
