A pedal assisted bicycle a first and a second wheel; a pedaling assembly mechanically decoupled from the first and second wheels by which an user can supply a pedaling power; an electric motor mechanically coupled to at least one of the wheels capable of taking a motor power; a generator device adapted to generate a generator device electric power from the pedaling power, arranged in an energy exchange relationship with the pedaling assembly and the electric motor; an energy storage device arranged in an energy exchange relationship with the electric motor and with the generator device; a control system including a module for controlling the power required to the generator device to be supplied to the electric motor and/or to the storage device; a heartbeat sensor adapted to generate a signal representing heartbeat.

Pedal assisted bicycle and method of controlling the pedal assisted bicycle

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.
