Now are you talking about the clueless public at large, or about a shepherd? The shepherd may want better information than you are providing. According to Sheep 101

"There are more breeds of sheep than breeds of any other livestock species. Worldwide, there are more than one thousand distinct sheep breeds. There are more than 40 breeds in the United States. Sheep come in all different sizes, shapes, and colors.

Breeds are usually classified according to their primary purpose (meat, milk, or wool), the type of fibers they grow (fine, medium, long or carpet wool; or hair), the color of their faces (black, white, red, or moddled), and/or by specific physical or production characteristics."

So obviously sheep can only be used as an overall category. Those who know, will desire more information as does a discerning bicyclist desire to know more about a bicycle.

Now I suspect that you haven't taken a poll of a representative sample (10,000,000,000 people to get the accuracy you specify or roughly 140% of the world's population) to back up your assumptions of what 99.99999999% think of when the word bicycle is mentioned. Nor have I, but it's possible that like my ex-wife, a non-cyclist, they relate bicycles to whatever they rode as a child or a simple bike. So they might think of a Sting Ray or a step through frame beach cruiser, neither of which are your typical diamond frame. We can make no assumptions of what stereotype people may have in their heads unless we have taken the effort to verify it.
