ABSTRACT:
A system for the proportional propulsion assistance by a DC motor propulsion secured to a wheel of a bicycle propelled by a user person who provides an effort. The system has a strain gauge for the detection and measurement of a flexion of a stationary shaft of a rear wheel of the bicycle. The gauge is disposed on a vertical face formed on the shaft. An amplifier amplifies a measurement signal coming from the gauge. A filter is connected at the input of the amplifier. An analog to digital converter is connected at the output of the amplifier. A digital processing circuit digitizes the signal at the output of the amplifier to compensate for any deviation of the signal to calculate, in real time, the effort provided by the user person on the gears secured to the rotor housing of the DC motor secured to the fixed shaft and to control the assistance effort provided by the DC motor of the rear wheel of the bicycle to give a progressive assistance to the user person.
