Between my daughters and myself we have 6 bikes and each has a name. We started naming inanimate objects starting with my first new car. Anyway here is a rundown.

Daughter Olivia: Specialized hard rock 24" = Bubbles
Daughter Maxime: Gary Fisher Piranha = Nemo
Daughter Maxime: Townie cruiser = Townie
Mom: Santa Cruz Superlight = Pip
Mom: Specialized Cirrus Pro = Milly
Mom and Maxime: Crapped out Huffy Cruiser = Crusty

Each name has a story but that would be entirely too long a response.
Of course we name them! They play an important role in our lives for fun, health, school transport and grocery schlepping.

BTW, the Honda Element is "Julius"
