i would advise you to get the loudest, biggest, mother of all bells fitted on your bike.
Everytime one of those jokers trys to rule the road with his bell I wish I had one attatched to my belt buckle to ring right back at them. I hate how the bikers assume that if you are anywhere near where they think they should be or if you are thinking about thinking about stepping toward them even if they are 200 ft. away they ring their bell.
Makes me want to get a loud big mother of all bells fitted on a bike and go for a ride just for the fun of pissing off some Deutschkopfs. Take an air horn. Hook it up to the Dynamo.
Another note. I saw a Donald Duck squeeze horn on one bike. Priceless.
