Some of the suggestions that you girls have put up have been amazing! I totally agree with the fashion thing. Matching gloves, coordinated helmet, bottles, etc with girly designs, even if you keep to the white and red, would definitely femme her up a bit A friend of mine has a bike where they powder coated her rims to match, and it looks pretty good.

Other things: Hints of pinks in gear, handlebar grips/tape, bags, etc

I love the custom bell idea! The ladybug one is so cute!
