The action exerted on a bicycle by a rider is a machine-like system through which movement and travel is achieved. The dynamic between a bicycle and a bicyclist depends on movement, the architecture of the bike, the structure of the environment such as pavement, and the physiological structure of the body. In these papers, researchers study the mechanisms of the bicycle-to-rider interaction to examine aspects of bicycling such as velocity, acceleration, levels of bicycle control, limb positions, bicycle frame, tire and road quality as they affect movement, and more.
