The invention relates to a vehicle, especially a bicycle, comprising at least one drive wheel (1), a motor (3) connected to the drive wheel (1), a power accumulator (5) for supply of the motor (3), a control device (6) for controlling the motor (3), and a pedal crank (7). The aim of the invention is to improve the handling characteristics of such a bicycle. For this purpose, the pedal crank (7) can be moved independently of the drive wheel (1) and is connected to a braking device (20, 21) that provides a moment of resistance to the rotation of the pedal crank (7). The moment of resistance of the braking device (20, 21) is controlled by the control device (6).
