1. A bicycle fitting system comprising:

  • a controller programmed to determine whether a current rider position of a rider satisfies a predetermined condition, the predetermined condition being based on a flexibility level of a rider body of the rider, the flexibility level expressing a flexibility of at least one joint of the rider body in terms of a flexibility category selected from at least two different flexibility categories; and

    a motion capturing apparatus electrically connected to the controller, the motion capturing apparatus includingat least three markers configured to be attached to a rider body of a rider,a sensor configured to detect positions of the at least three markers while the rider is on a bicycle fitting equipment configured to simulate riding a bicycle;

    the controller being programmed to determine the current rider position by measuring at least one rider body parameter of the rider body using the motion capturing apparatus while the rider is on the bicycle fitting equipment, the at least one rider body parameter including at least one angle between three of the markers,the controller being programmed to determine whether the predetermined condition is satisfied by determining whether the at least one angle lies within a parameter range selected based on the flexibility level of the rider body, andthe controller being programmed to calculate bicycle fitting information indicating a bicycle component position of a bicycle component based on the current rider position and the selected parameter range, and output the bicycle fitting information to an output apparatus.
