There is a mindset. An independent mindset that some ladies have that stirs that curiosity. As an example, I would like to share an experience.
We have a daughter that works in S. Korea. A few years back she came home for a year. After arriving, she bought a car. She went to the store and brought back some accessories and bits she wanted to install. She took the parts, looked everything over, came and asked me for the tools (and I mean something like, "Can I get a ratchet with a 7/16" socket, a 1/2" wrench and a Phillips screwdriver?"). I gave her the tools and she went outside. She didn't ask for help and I didn't offer. Not because I didn't want to help her, but that she didn't want my help. She is accustomed to doing things for herself. She wants to do things for herself. She has taken herself around the world and toured Europe with very little help from home. Oh, she uses a bike for transportation in S.Korea, by the way.
My point is that the more independant thinking ladies that are out there may, at some point, want to start tinkering on there own bikes. It adds to that independant feeling. And this proud papa is glad to see it.
