Try to find a local bike shop and chat with some of the people there. Let them know that you’re clueless and not ready to buy a bike but are trying to figure out what you need. Maybe make a smaller purchase like a helmet to support them in return for advice.
They may even let you test-ride a thing or two!
As long as she has a personality to back up her looks, sure. A little bit of marketing to get a sale works well in my experience.
