The Gyrowheel contains a motor-driven flywheel that spins independently, and uses the principle of gyroscopic precession to help stabilize the bike and the rider.

There is no connection between them, so they spin independently.

This method proved to be inadequate, and the cam sprocket could break loose from the camshaft and spin independently from the camshaft (or "walk").
