The present invention relates to a momentum measurement device for a bicycle using the tension of a chain and, more specifically, to a momentum measurement device for a bicycle using the tension of a chain capable of measuring a displacement occurred by the vertical movement of a lifting member, a revolutions per minute of a sprocket, and a pressure applied to the sprocket using tension applied to a chain of a bicycle when a user works a pedal of the bicycle and conveniently and accurately calculating a momentum of the bicycle user based on the measured operation data. According to the present invention, the momentum measurement device for a bicycle using the tension of a chain mounted on a bicycle to measure a momentum of a bicycle user comprises: an elastic compression part elastically compressing an upper chain of a chain to connect a crank and a sprocket to each other in a vertical direction and having a lifting rod vertically moved by tension applied to the upper chain when a pedal of the bicycle works; a sensing part having a displacement detection sensor to measure a displacement occurred by the vertical movement of the lifting rod; and an operation part to calculate a momentum of a bicycle user by operating the displacement value measured by the displacement detection sensor. |
