"Mountain bikes have wheels"? Good Lord man. Haven't you figured it out
yet? "Bike" is a contraction of the word "bicycle" and "bi" is a synonym
for "two" and "cycles" is, again a synonym, for circle, or in this case
"wheel".

You are aware that bicycles were at the forefront of the modern world.
Their development lead to the great transport revolution.
