What are the 3 main steps of riding a bike?

Can you elaborate on the fundamental steps required to successfully ride a bike? Are there three key processes that must be mastered in order to achieve balance, control, and forward motion? I'm particularly interested in understanding the sequence and importance of these steps, as well as any tips or techniques that might aid in mastering them. Could you please provide a concise yet comprehensive description of the three main stages involved in learning to ride a bike?
