摘要： A measuring apparatus and method for measuring dynamic parameters in a driven bicycle wheel are described. Parameters which are measured are; driven torque, angular velocity, angular acceleration, lateral angular acceleration, and applied power of the driven wheel. The measuring apparatus is affixed to the rear driven cog(s) of a bicycle wheel. One or more strain sensing elements affixed to the rear driven cog(s) detect the applied driven torque. Three or more acceleration sensing integrated circuits are used to determine angular velocity, angular acceleration, and lateral angular acceleration of the driven rear cog. These circuits reside on the primary electronics board and are affixed to the rear driven cog; hence they rotate along with the driven rear cog. Power applied to the driven wheel is derived from the torque and angular velocity measurements of the invention. These performance variables will aid a competitive cyclist to evaluate and observe progress in his or her physical training.
