MTBs really are some of the most versatile bikes ever built. They can be used and abused by kids and adults in a way other bikes can’t. You can take them around the world, cruise a country trail, and even go up and down mountains on them.
Mountain biking can generally be broken down into multiple categories: Cross Country, XC, Trail riding, All-Mountain (also referred to as "Enduro"), Downhill, Freeride, and Dirt jump and Trials riding. There are various wheel sizes available 26" 27.5" and 29"
