Rolling resistance of a bicycle tire is the main factor that affects the characteristics of two-wheeled vehicles. The study of rolling resistance allows better evaluating the advantages of different wheel diameters. Since rolling resistance is an indicator of the vehicle behavior on a particular terrain, it can be considered an objective parameter for comparing the characteristics of two wheel sizes (26 and 29 inches). The purpose of this study was to evaluate rolling resistance of mountain bikes, depending on several parameters: wheel diameter, terrain type, cyclist mass, tire pressure, and suspension type.
