Well, there are places where mounting a bicycle bell is not mandatory. People can just say excuse me, and that works. But if you think about it, you may be better off with a bell that is not very loud to annoy the pedestrians. If you are not sure, you can buy a digital horn with different volumes of sound. You can choose a pleasant sound level based on your location. Well, a personalised product like this always comes to the rescue when you get confused about buying a product. But keeping your personal thoughts aside, these bells are a must-have.
