Herein described is a bicycle comprising a frame, a drive wheel and a pedal crank/pedal assembly which transmits mechanical energy to the drive wheel by means of a transmission system which comprises: a tank containing a hydraulic fluid; a hydraulic circuit in which the hydraulic fluid flows; a hydraulic pump, actuated by the pedal crank/pedal assembly and configured to pump the hydraulic fluid through the hydraulic circuit; at least one hydraulic actuator, arranged along the hydraulic circuit and configured to transform the hydraulic energy supplied by the hydraulic pump to the hydraulic fluid into mechanical energy; and a drive shaft, connected to the hydraulic actuator and configured to transfer the mechanical energy generated by the hydraulic actuator to the drive wheel. The hydraulic pump is connected to an electric motor whose rotational speed, as well as the operating parameters of the hydraulic pump, are controlled by a circuit board. The bicycle comprises at least one first pedal frequency sensor, which controls the electric motor by modulating its rotational speed, so as to make the hydraulic pump rotate more or less rapidly in order to force the circulation of the hydraulic fluid in the hydraulic circuit, facilitating pedalling, and at least one second power sensor, which measures the power applied by the cyclist to the pedal crank/pedal assembly, so as to accordingly adjust the power supplied by the electric motor to drive the hydraulic pump.
