Yes? That's how it works.
You can draw a triangle and label the points "highway," "dirt," and "urban" and any bike you pick will describe a dot in one position on that triangle and never ever touch all three points at the same time.
All vehicles are for the purposes of transportation (or recreation), just possibly for moving different types of things across different terrain with different strengths and weaknesses. You're trying to split a hair that doesn't need to be split as if it's some kind of "gotcha" that everyone in the world knows is irrelevant except you.
