A bike horn is a small device attached to a bicycle that produces a loud sound to alert others. It helps cyclists communicate their presence to pedestrians and other vehicles, enhancing safety on the road. Bike horns come in various styles, including squeeze horns and electronic models, making it easy for riders to choose one that fits their needs. Using a bike horn is especially important in busy areas or during low visibility conditions. By sounding the horn, cyclists can prevent accidents and ensure that everyone shares the road safely. Whether you're riding in a city or on a trail, a bike horn is a handy tool for any cyclist.
