A pedaling motion measuring device of the present invention includes: a measurement body unit (2) that has a first sensor unit (21, 22) for sensing the number of rotation of a wheel (104) by sensing the motion of the wheel of a bicycle, and second sensor units (4, 5) arranged at right and left crank arms (107) for sensing magnitude and direction of a force applied to each of the right and left crank arms; a first work calculation unit (8b) that calculates work performed by the bicycle within a prescribed time based on the number of rotation of the wheel sensed by the first sensor unit (21, 22); a second work calculation unit (8c) that calculates work provided to the crank member by the user within a prescribed time, based on the magnitude and direction of the force applied to each of the right and left crank arms (107) and sensed by the second sensor units (4, 5); and an efficiency calculation unit (8d) that calculates the efficiency of the bicycle based on the work of the bicycle and the user's work. |
