What is Precession? Gyroscopes are spinning wheels that exhibit a special property called precession. When a force is put at the top of a spinning wheel (such as a rider falling on a bicycle), rather than falling, the gyroscope simply turns, or precesses, in the direction of the fall. This occurs on normal bike wheels when the bike is traveling at higher speeds. Hence, it is easier to ride a bicycle once you "get going". Gyrobike takes advantage of this property even when the bike is moving slowly. The flywheel inside the Gyrowheel spins independently of the bike wheel. Thus, even when a rider is moving very slowly on his or her bicycle, the precession of the Gyrowheel is still felt. If the rider begins to fall, the Gyrowheel precesses under the rider's weight, restabilizing the bike.
