Description of the Animation
The swing arm is formed by the cyclist’s thigh. It extends from the hip to the knee joint. A swing arm enables a swinging movement around a pivot point.
The connection between the knee joint and the pedal axle is called a linkage. A linkage is a connection between two moving parts.
The pedal lever is also referred to as a crank in this context. A crank is a component that enables rotating movement.
The static connection between the pedal axle and the hip joint is the so-called frame. The frame has a rigid structure.
