Well, that seems to be the heart of the disagreement. Some people feel that you can add a motor to a bicycle, and you still have a bicycle. Others feel that when you add a motor to a bicycle, you no longer have a bicycle; the non-motorized aspect of bicycling is fundamental to the definition of what a bicycle is.

I'm sure the laws defining what is and what is not a bicycle are the best that lobbyists money can buy. They can define ketchup to be a vegetable too. I'm not buying that either.
