What are the key differences between a recumbent bike and a trike, and which one would be more suitable for someone looking for a comfortable and stable riding experience?

A recumbent bike is a two-wheeled bicycle where the rider sits in a reclined position, while a trike is a three-wheeled bicycle with a more stable base. The trike would be more suitable for someone looking for a comfortable and stable riding experience due to its extra wheel providing more balance and stability compared to a recumbent bike.
