The gyroscopic action of the wheels is negligible in balancing a bicycle. Think of a child’s scooter with its tiny wheels, or an ice skate with no wheels at all.
Balance is achieved by the rider constantly moving their centre of gravity slightly to one side or the other. To stay stationary, a rider moves slightly back and forward, as well as shifting side to side. This is observed with unicyclists.
