All my bikes are named for ex-girlfriends.
Katrina (the best looking girl I ever dated), is my carbon framed road bike. She’s lightweight and pretty and fun to ride, but she’s high maintenance and prone to break-downs at inopportune moments.
Cheryl (the one I should have married), is my steel framed commuter. She isn’t as attractive or as fun to ride as Katrina, but she’ll let you ride her anytime and take all of the abuse you can heap on her. She never complains and requires very little maintenance even though I ride her more than all my other bikes combined.
Susan, my grocery bike, is an old hybrid I spray painted and put a bunch of cheap Wald baskets on to make her look bad. I try to load her down as often as possible and generally treat her badly. She stays in the garage instead of in the climate controlled workshop with the rest of my bikes. I named her after my ex-wife.
