Abstract: A measuring device for a pedal plane angle of a bicycle includes a pedal body, an angle sensing unit and a central processing unit (CPU). The angle sensing unit is disposed in an accommodating chamber of the pedal body, and senses an angle of the pedal body to send an angle sensing signal. The CPU analyzes the angle sensing signal to obtain angle data of the pedal body relative to an angle of a reference plane to accordingly learn an angle relationship between the pedal body and the reference plane. The angle relationship may coordinate with other sensing units, for example, data of a pedaling force sensing unit to mutually correct and analyze the data, so as to obtain correct pedaling force information. With the angle data, whether a pedaling angle of a rider is correct can be learned to prevent sports injuries caused by incorrect pedaling angles.

Abstract: An electromagnetically actuated bicycle trainer includes a base, a support assembly disposed on the base, and a hysteresis resistance generating module. The support assembly includes a support arm, and a fastening member disposed on the support arm and for securing an axle of a pedaling wheel. The hysteresis resistance generating module includes an inner magnetic stationary member and an outer magnetic stationary member, a semi-hard magnetic rotating member between the inner magnetic stationary member and the outer magnetic stationary member, and a conductive coil. The conductive coil receives an electric power and senses opposite magnetisms that the inner magnetic stationary member and the outer magnetic stationary member generate. Thus, the semi-hard magnetic rotating member is caused to generate a hysteresis resistance when rotated in response to hysteresis effects.
