on a moe level,
Does she ride a bicycle? Has see ever?
Yes? Good. No? not so good.
Yes: Samuel Johnson "The Great Cham of Literature" regarding Dreams of Avarice, er see above post.
No: Get a couple of mountain bicycles and ride together. Then entertain thoughts of a motorsickle. Why? You'll be able to observe her spacial intuition while she is in action. Which will afford you the words you will use to discuss her two wheel desires. Mountain biking is great fun and a great way to intimately ride.

in public.
Good luck.
