I carry a bell in my saddlebag.
When I go on a long (overnight stay or longer)ride with a group of riders. I will take the bell from my bag and attach it to the throttle of someone that I feel needs or deserves a bell. I tie the bell when no one is paying attention. I will do this unanimously.
I feel the bell is more potent when given this way.
I have given away 4 bells at this time. I plan to keep this tradition going.
