The good book "Google" says:
The Purpose of the Guardian® Bell
Many of us have heard the story about Evil Road Spirits. They are little gremlins that live on your bike. They love to ride, and they’re also responsible for most of your bike’s problems. Sometimes your turn signals refuse to work; your battery goes dead, the clutch needs adjustment, or any of several hundred things that can go wrong. These problems are caused by Evil Road Spirits.
Evil Road Spirits can’t live in the presence of the bell, because they get trapped in the hollow of the bell. Among other things, their hearing is supersensitive, so the constant ringing of the bell and the confined space drives them insane. They lose their grip and eventually fall to the roadway. Have you ever wondered how potholes are formed? The bell has served its purpose.
If you pick up a Guardian® Bell of your own, the magic will work, but if your bell is given to you, the power is doubled, and you know that somewhere you have a special friend helping to look after you.
So, if you have a friend who doesn’t have a bell, why not give them one? It’s a nice feeling for the recipient to know you care. The bell, plus a good preventive maintenance program by the bikes owner, will help eliminate Evil Road Spirits.
