It isn’t. A unicycle does not ride by itself; only with the addition of a
person (or orangutan or chimpanzee) is it a viable vehicle.
The assumption is that the rider is many times heavier than the unicycle,
and the center of mass is roughly somewhere back of the rider’s belly
button. Sorry, not very technical. But the exact location is going to vary
with each person, each unicycle, and with any other weight they’re carrying,
such as clothing.
Also, I think you can leave out the wheel from most of this “center”
figuring, as it is the part that gets adjusted to correct the balance. The
part of the unicycle from the wheel bearings up gets counted along with the
rider as the moving part, with the center of mass in it.
The unicycle is ridden by moving both the pedals and the body, adjusting the
relationship between the center of mass and the contact point of the tire
with the ground.
I never took a physics class, but I think it’s a combination of several
different type of physics concepts, used together, that make a unicycle
Watch videos of people doing tricks and riding trails and Trials to see the
physics in action. You can learn a lot by watching people move.
