Wheeled vehicle with electric drive in the rear frame triangle and electric motor for a wheeled vehicle

A wheeled vehicle with a crank drive and an electric drive, comprising:

• a) a frame which serves to suspend a front wheel and a rear wheel and comprises a seat tube, an upper rear wheel stay and a lower rear wheel stay which together at least substantially form a frame triangle for suspending the rear wheel;
• b) a crank for converting muscular strength into torque;
• c) a crank coupling for transferring the torque of the crank onto the rear wheel;
• d) an electric motor comprising a stator and a rotor;
• e) and a motor coupling for transferring a torque of the electric motor onto the rear wheel;
• f) wherein the crank and the electric motor output onto the same side of the rear wheel, and g) the electric motor is supported on the frame triangle h) and arranged within the frame triangle as seen in a lateral view of the wheeled vehicle,
• wherein the electric motor is supported on the upper rear wheel stay by means of an upper support and on the lower rear wheel stay by means of a lower support, wherein a traction means of the crank coupling extends in a free space.

An electric motor for driving a wheeled vehicle, said electric motor comprising:

• a) a stator;
• b) and a rotor with a rotor cup which comprises a base and a circumferential wall and surrounds the stator on a facing side with its base and circumferentially on an outside with its circumferential wall;
• c) wherein a part of the rotor which electromagnetically cooperates with the stator when the electric motor is in operation is arranged on the circumferential wall of the rotor cup or forms the circumferential wall, d) and wherein the rotor cup forms a housing of the electric motor which rotates when the electric motor is in operation, e) and the stator forms a stator cover which closes the rotor cup off in a water-proof seal,
• wherein the stator comprises a stator cover with a central, sleeve-shaped bearing region and a flange region which projects radially outwards from the central bearing region;
• an electromagnetically active part of the stator is arranged on an outer circumference of the central bearing region;
• and the flange region of the stator forms the stator cover for closing the rotor cup off in a water-proof seal.
