It is described an electronic system () to drive an electric device () of a bicycle assisted electrically () by means of a rechargeable battery (). In case of detecting that the calculated human power is greater than or equal to the bicycle estimated friction power and in case of detecting that the state of charge of the battery () is greater than or equal to a first threshold, the processor is such to generate a driving current value for driving the electric device () operating as an electric motor () supplied from the battery (). In case of detecting that the calculated human power is smaller than the estimated bicycle friction power, the processor is such to convert at least part of the human power into electric power by means of the electric device () operating as an electric generator (), and generate therefrom another driving current value for charging the battery () from the electric device operating as electric generator.

The present invention refers to a method for estimating the suspension stroke of a vehicle comprising the steps consisting of: a) determining a variability law () that associates the stroke of the suspension with the pressure inside a shock absorber of the same, based on experimental data; b) estimating the suspension stroke value related to a measured pressure value, based on the variability law () identified in step (a); c) detecting/obtaining the longitudinal vehicle dynamics; d) recalibrating () the variability law () identified in step a), based on the longitudinal vehicle dynamics detected/obtained in step c). The present invention also refers to an apparatus for implementing the estimation method of the suspension stroke of a vehicle according to the invention.
