Driving unit for an electric vehicle

A driving unit for an electric bike, the driving unit comprising:

• a pedal system comprising a pedal gear wheel configured to rotate in a first rotation direction around a first axis based on an input mechanical energy provided by a user of the electric bike;
• an electric generator configured to be connected to an external battery;
• a first intermediate gear system configured to connect the pedal system to the electric generator and configured to transmit the input mechanical energy of the pedal system to the electric generator, such that the electric generator rotates around a second axis in the first rotation direction or in a second rotation direction being opposite to the first rotation direction, thereby generating an electric power;
• an electric motor configured to rotate around a third axis based on an electric energy provided by the external battery and/or by the electric generator in the rotation direction being opposite to the rotation direction of the electric generator, wherein the rotation of the electric motor is mechanically independent from the rotation of the pedal system;
• an output gear wheel configured to be connectable to at least one wheel of the electric bike by means of an external transmission system configured to connect the output gear wheel with the at least one wheel of the electric bike to cause the electric bike to travel forwardly or backwardly in a direction of travel;
• a second intermediate gear system configured to transmit the rotation of the electric motor to the output gear wheel, such that the output gear wheel rotates in the first rotation direction;
• and
• a control unit configured to control the rotation of the electric motor.
