Fat Cyclist on why mountain biking is too broad of a term:
So here’s the thing. If someone tells you they went out road biking, you have a good idea of what went on. You may not have an idea of how far, how fast, or how steep, but you know what road biking looks like.
If someone tells you they went mountain biking, on the other hand, you still don’t know anything.
Ain't that the truth?
