Once you see how a trackstand is done it breaks the gyroscopic myth immediately.

The easiest bike to trackstand is a fixed gear, you turn the front wheel about 45 degrees to one direction or the other, then find the balance point, with the cranks leveled out. Pedaling forward leans you one way, pedaling backwards leans you the other way.

The next difficulty step is a conventional bike, if you have a slope to point your wheel up, that replaces the ability to pedal backwards.

The final difficulty level is replacing the slope with just brake modulation and body weight.
