The language of mountain biking or more precisely the “MTB slang” can be very confusing. But don’t be alarmed, that’s normal. Even veteran riders are sometimes baffled with what their mates are saying. Like some other sports, mountain biking has developed its own language over the years, and it’s always evolving.

Here, I won’t cover terms like bike parts or tricks name, but terms riders are using most often. Terms to describe their riding, the trails, and their feelings. Also, this is not an exhaustive dictionary, but more of an amalgam of the most common terms you will hear on the trails.

About Your Riding

The language of mountain biking includes a lot of specific terms to describe one’s riding style. Let’s drop in on those terms:

AIR – The space between both tires and the trail when you leap over obstacles or jump. You get or catch air.

BOMB – Riding a descent very fast without minding what might happen as a result. 

BUNNY HOP – A technique to get over obstacles without stopping. You get both wheels off the ground, but not at the same time. A great skill to have to be able to clear technical features such as rocks, logs, and potholes without stopping.
