I never name them, but they sometimes arrive at the stable with a name already attached. Only two of the twenty or so currently in residence currently have names: Betsy (an old Schwinn lugged frame converted to fixed gear decades ago, named by by sister-in-law) and Wicked Witch (my mom's Schwinn step-through from the '70s, named by my sister). Since these are the two bikes with the largest baskets, they get the most in-town miles.
