Some of the forces that you may have seen in the video and have mentioned in your answer are contanct forces. Examples of these pairs of contact forces are the interactions between the road and tires (the force of the road acts on the tires, and the force of the tires acts on the road), the biker and the air, and the seat and the biker. Any pair could be analyzed as a system of interacting forces. Other force pairs can act at a distance, such as the force of gravity between Earth and the rider.
