My mountain bike is "Miss Bike", She's a ball burnished Zaskar who wears pearls, WOMBAT, and has nice manners the way an Irish thoroughbred hunter does- elegant handling with a totally mad glint in her eye going cross country. Yes, she does have an eye, on her head tube.
My road bike is "Road Warrior Barbie"- the paint is pink and green and white interference (sparkly-ish) on a stand up racing geometry. With butterflys all over.
My BMX cruiser is "Little Horse", cause it's a pony version of a bike to scoot around campus on.
