Claim:
1. A measuring system for analyzing a knee joint motion trajectory for measuring and analyzing the knee joint motion trajectory when a rider is riding a bike, comprising: a pedal-able device which is a frame including a frame stem and a pair of pedals, for allowing the rider to place his/her feet on the pedals; a light emitting component fixed at a tibial plateau of a lower limb of the rider, for emitting lights when the rider continuously pedals the pedal-able device; an image capturing device disposed at the front of the pedal-able device, wherein when the rider continuously pedals the pedal-able device, the image capturing device captures an image including the central position of the lower limb of the rider and a light spot trajectory image of the light emitting component; a knee joint motion trajectory analysis device, connected with the image capturing device, wherein the image capturing device inputs the image of the central position of the lower limb of the rider and the light spot trajectory image of the light emitting component to the knee joint motion trajectory analysis device, and the knee joint motion trajectory analysis device includes:
