    The invention relates to a bicycle with a pedal crank drive and with an electric auxiliary drive connected to the pedal crank drive, which has a wheel hub motor with a freewheel hub for the rear wheel.
    In order to create advantageous construction conditions for auxiliary electric drives in bicycles, it is known to provide a wheel hub motor for the rear wheel, attack the spokes directly on the wheel hub motor. The pedal crank drive is connected to the freewheel hub of this wheel hub motor, whereby usually a manual transmission is interposed in order to be able to provide an advantageous cadence range for the pedal crank for a comparatively large speed range. This means when providing a gearshift that a Fahr-wheel users the gearshift must operate accordingly to be able to specify advantageous in terms of the pedal crank drive conditions. Although these difficulties can be avoided by an automatic transmission, but also an automatic transmission can not influence the resulting from the engine load due to the driving resistance resulting operating point of the wheel hub motor.
    The invention is therefore based on the object, an electric auxiliary drive for a bicycle in such a way that on the one hand a cadence for the pedal crank mechanism in a predetermined range adhered and on the other hand, an automatic adjustment of Hiifsantriebs to the particular driving conditions can be achieved.
    Starting from a bicycle of the type described above, the invention solves the problem set by the fact that the wheel hub motor for the rear wheel via a 2 gear transmission with an electric auxiliary motor of the same size is drive connected.
    The rigid drive connection between the wheel hub motor and the auxiliary motor under a predetermined transmission ratio ensures that the two motors are operated in different work areas. This means in the usual for the rim motors used speed-torque characteristic in which the speed decreases with increasing torque that one of the two identical engines due to the gear ratio at an operating point corresponding to the lower speed and the other motor at an operating point corresponding to the higher Speed can be operated with the effect that the engine operated according to the translation at the lower speed is used in particular at higher speeds, while the engine, which is operated at higher speeds, comes into effect at low speeds when the speed of the lower speeds operated engine fall below a level that makes stable engine operation difficult. Due to the two identical motors of the electric auxiliary drive thus effectively an elastic, electrical axis is created, which allows a powerful ferry operation without an additional gearbox. It only has to be ensured that a sufficiently large transmission ratio is present in order to be able to use correspondingly different operating points for the two identical motors. The distribution of the required drive power to two identical motors also brings with it the advantage that smaller sizes of these motors can be used.
    The transmission gear could be designed as a gear transmission. Simpler construction conditions arise, however, if the transmission gear is designed as a circulating traction mechanism, so for this purpose proven chain or timing belt drives are used. If a transmission ratio between the rotational speed of the wheel hub motor for the rear wheel and the rotational speed of the additional motor greater than 1 vorge 3 see for the transmission gear, so the wheel hub motor for the rear wheel operated at a higher speed, so the bike on the electric auxiliary drive with a higher Speed be driven. The pedal crank drive engages in this case on the freewheel hub of the additional motor.
    In the drawing, the subject invention is illustrated, for example, and that a bicycle according to the invention is shown in a schematic side view.
    The illustrated bicycle has a frame 1 with a bearing 2 for a steering column 3, which carries a bearing fork 4 for a front wheel 5. The mounted in the frame frame 1 rear wheel 6 is provided with a wheel hub motor 7, on which engage the spokes of the rear wheel 6, which is not shown for reasons of clarity. The wheel hub motor 7 is connected via a transmission gear 8 supported on a frame frame 1 auxiliary motor 9 of the same type and size, which acts as a rotating traction drive 10 with a chain or a toothed belt as a traction mechanism formed transmission gear 8 on the freewheel hub of the wheel hub motor 7. The mounted in the frame frame 1 pedal crank 11 of the pedal crank 12 is drivingly connected via a rotating traction means with the freewheel hub of the auxiliary motor 9.
    Since, according to the illustrated embodiment, the wheel hub motor 7 is operated at a higher speed than the identical auxiliary motor 9 due to the selected transmission ratio of the transmission gear 9, the high torques of the wheel hub motor 7 can be used at sufficiently high speeds for a stable drive, the in Range of additional motor 9 under certain circumstances could no longer ensure the drive stability. At higher speeds, the higher torques of the operated at a lower speed additional motor 9 are then used for the electric auxiliary drive. Prerequisite for this is a sufficiently large gear ratio. For example, a ratio of 1: 2 has proved to be advantageous. 4
    The electric auxiliary drive can be supported in a conventional manner by the pedal crank 12. For this purpose, the pedal crank 12 is to be connected to the freewheel hub of the engine, which is operated at a lower speed. The pedal crank 12 is to be interpreted for this purpose with a corresponding translation.
    It probably does not need to be specified that the front wheel 5 can be driven by a wheel hub motor 13, as indicated in the drawing. In this case, a four-wheel drive bicycle is achieved, which has particularly good driving characteristics with a corresponding control of the wheel hub motor 13 for the front wheel 5, without having to provide a manual transmission.
