MUni stands for Mountain Unicycling. It’s also known as Rough Terrain Unicycling, All Terrain Unicycling, or even UMX. Like mountain biking, you don’t need a mountain to do it. It’s just the act of riding unicycles off road.
MUni has been a revolution in the unicycling community, sparking a tremendous effort to build better, stronger unicycles. Some of this new technology has of course spread to other types of unicycles; good for everybody! There is just something satisfying about taking an inherently unstable vehicle like a unicycle, and riding it in places nobody thought it could go. The early years of MUni led to vast strides in the types of terrain that can be successfully ridden by unicycle. Certainly anyplace a bike can go, a unicycle can follow. You will find that you can turn quicker or fit through narrower spaces than the bikes can.
