My green single speed that I built out of used parts is my everyday bike, her name is GiGi Swing.
My blue peugeot commuter is Buddy.
My BMX Haro Backtrail X3 is Lucky...he has an interesting story that comes with the name too.
My 2002 Gary Fisher Big Sur is Marla...I love her
And, I have a 1975 Kabuki Bridgestone ten speed that is too big for me, but in great condition, and I got it for free. Sadly it doesn't have a name yet, but it feels like a Karen to me.
Let me know if you have bikes with names.
