METHOD AND SYSTEM FOR MEASURING AT LEAST ONE PHYSICAL PARAMETER FOR A BICYCLE

A method and system for measuring a physical parameter, such as speed and/or distance travelled by a bicycle, includes a permanent magnet disposed on a front fork and a measuring circuit with a magnetic sensor disposed on a rim of the wheel at the same distance from the axis of rotation of the wheel as the magnet. The sensor passes in front of the magnet, in order to generate an induced voltage pulse at each passage. The induced voltage is rectified and stored on a capacitor to power the measuring circuit. A calculation of the parameter is performed in the calculation unit clocked by an oscillator based on the received induced voltage pulses received by knowing the value of the diameter of the bicycle wheel. Measurements performed from the measuring circuit are transmitted to a portable device carried by the user or mounted on the bicycle to be displayed.
