You walk into the custom frame builder's shop and tell him you want a racer, a mtb, a touring bike. "Step into this body scanner we borrowed from TSA." he instructs. Couple minutes later the computer has an exact copy of your dimensions as well as design details for 3 custom frames. A month and $20,000 later, you're delivered 3 bicycles that fit you perfectly. Any conceived imperfection will be your imagination. Get over it.

Technically, this scene is already possible. When is the question.
