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).

The invention claimed is: 1. A vehicle which comprises: a drive wheel, a motor connected to the drive wheel, a power accumulator for supplying power to the motor, a pedal crank which is independently movable relative to the drive wheel, a control unit for controlling the motor, a braking unit which is controlled by the control unit and provides a resistance torque opposing rotation of the pedal crank, and wherein the control unit is implemented in such a way that a ratio of the speed of the pedal crank to a speed of the drive wheel is constant step-by-step. 2. The vehicle according to claim 1, wherein the braking unit comprises a flywheel. 3. The vehicle according to claim 2, wherein the flywheel is connected to the pedal crank via a gear which increases the speed and which has a transmission ratio of at least 1:3. 4. A vehicle which comprises: a drive wheel, a motor connected to the drive wheel, a power accumulator for supplying power to the motor, a pedal crank which is independently movable relative to the drive wheel, a control unit for controlling the motor, a braking unit which is controlled by the control unit and provides a resistance torque opposing rotation of the pedal crank, and wherein the control unit is implemented in such a way that a ratio of the speed of the pedal crank to speed of the drive wheel corresponds variably to a predefined value step-by-step. 5. A vehicle which comprises: a drive wheel, a motor connected to the drive wheel, a power accumulator for supplying power to the motor, a pedal crank which is independently movable relative to the drive wheel, a control unit for controlling the motor, a braking unit which is controlled by the control unit and provides a resistance torque opposing rotation of the pedal crank, and wherein the control unit is implemented to keep the power applied at the pedal crank at a constant ratio to the power delivered at the drive wheel. 6. The vehicle according to claim 5, wherein the control unit controls the motor as a function of torque instantaneously applied using the pedal crank and/or a variable related thereto, such as power or speed, using chronological smoothing. 7. The vehicle according to claim 6, wherein the smoothing only compensates for unintended short oscillations caused over one rotation by alternating load of the human legs, but recognizes intentional accelerations or velocity reductions and implements them immediately. 8. The vehicle according to claim 7, wherein the chronological smoothing is implemented by an analog low-pass filter in the control unit. 9. The vehicle according to claim 8, wherein the chronological smoothing is digitally implemented by calculating a sliding average in relation to the instantaneously applied torque using the pedal crank. 10. The vehicle according to claim 8, wherein the chronological smoothing is implemented by an integration element in the control unit. 11. The vehicle according to claim 8, wherein the chronological smoothing is implemented by establishing a continuous or step-by-step variable highest velocity, which is set via a control lever or a handlebar throttle. 12. The vehicle according to claim 11, wherein the motor is implemented as an electric motor, and the chronological smoothing is implemented by a capacitor which is connected in parallel to the electric motor and/or to the generator. 13. The vehicle according to claim 12, wherein the resistance torque of the braking unit is controlled by the control unit. 14. The vehicle according to claim 13, wherein the motor is implemented as an electric motor, and a power accumulator is provided for supplying the electric motor. 15. The vehicle according to claim 13, wherein the motor is implemented as an internal combustion engine having internal combustion. 16. The vehicle according to claim 15, wherein the braking unit comprises a generator. 17. The vehicle according to claim 16, wherein the generator is activated by the control unit. 18. The vehicle according to claim 17, wherein the braking unit comprises a hydrodynamic brake. 19. The vehicle according to claim 17, wherein the braking unit comprises a mechanically acting brake. 20. The vehicle according to claim 19, wherein the control unit is also used for braking the vehicle. 21. The vehicle according to claim 20, wherein the braking unit is implemented as a combination of a mechanical brake and a hydrodynamic or electrical brake, and the mechanical brake is primarily used when starting or in the event of strong accelerations, and the hydrodynamic or electrical brake is primarily used in continuous operation and in the event of light accelerations or decelerations. 22. The vehicle according to claim 4, wherein the braking unit comprises a flywheel. 23. The vehicle according to claim 22, wherein the flywheel is connected to the pedal crank via a gear which increases the speed and which has a transmission ratio of at least 1:3. 24. The vehicle according to claim 5, wherein the braking unit comprises a flywheel. 25. The vehicle according to claim 24, wherein the flywheel is connected to the pedal crank via a gear which increases the speed and which has a transmission ratio of at least 1:3.
