My current road bike is called Cleo, but she's a Genius Cleo 105 so she was named when I got her and has her name painted on her frame:

My first road bike was a red, black and silver Diamondback Interval. She was called Lola (as in Run Lola Run), because she was red and she went fast.

Most of our cars have had names as well. Our last car was an apricot VW Polo nicknamed Piglet. My husband rides an orange and black Peugeot scooter and he agonised for a long time over what to call it. He finally settled on Black Wolf (from Dr Who).
