Everyone at work calls my bike "My Wife". I call her Harmony (long story, don't ask.)

I would suggest naming it a name you can't put a face to. For example, you call it "Tabitha" and you meet a "Tabitha" and this "Tabitha" ends up being a huge "B***h", then you have a bike that everytime you ride it, you think of this "b***h".......which now means your bike is a "b***h".
