Measuring device and measuring method for measuring bicycle pedaling frequency

A measuring method, comprising:

• producing an acceleration signal associated with an acceleration waveform information according to an acceleration of a bicycle by an acceleration sensing module;
• acquiring the acceleration waveform information from the acceleration signal according to a predetermined parameter by a signal acquisition module electrically connected to the acceleration sensing module;
• and
• calculating a pedaling frequency data of the bicycle according to the acceleration waveform information by a pedaling frequency calculation module electrically connected to the signal acquisition module.

A measuring device, comprising:

• a bicycle component, configured to be mounted on a part of a bicycle that is not movable in a circular motion;
• a control unit, disposed in the bicycle component;
• a power supply unit, disposed in the bicycle component and electrically connected to the control unit for providing electricity to the control unit;
• and
• an acceleration sensor, disposed in the bicycle component and electrically connected to the control unit, wherein the acceleration sensor is configured to produce and provide an acceleration signal of the bicycle to the control unit to allow the control unit to calculate and produce a pedaling frequency signal according to the acceleration signal.
