My old 3-speed beach cruiser was "Edith" and my road bike is "Lexi". I named her Lexi because that sounds like a fast, sleek, beautiful, sophisticated name.

It helps with work excuses too. "Sorry I couldn't make it in for the first part of the meeting. Lexi needed a little extra attention this morning." When you say something like that, people won't say "Who's Lexi?" because they think they're supposed to know and they walk off scratching their heads. I can hear their thoughts "I know she doesn't have a small child. Does she? No - but she doesn't have grandchildren, either. Her niece? Whatever."
