Drive unit of a vehicle which can be operated by means of muscle power and/or motor power

A drive unit of a vehicle which can be operated by means of muscle power and/or motor power, comprising:

• a motor having a motor axis;
• a crankshaft having a crank axis;
• a transmission that mechanically couples the motor and the crankshaft;
• and
• a housing in which the motor and the transmission are arranged,
• wherein the transmission comprises at least a first gear wheel rotatable about the motor axis and a second gear wheel rotatable about the crank axis,
• wherein the housing comprises precisely two fastening regions, the two fastening regions including a first fastening region and a second fastening region,
• wherein the first fastening region and the second fastening region are configured to fasten the drive unit to a frame interface of the vehicle which can be operated by means of muscle power and/or motor power,
• wherein, in a cutting plane through the drive unit and orthogonal to the crank axis:
• a longitudinal axis is defined that intersects the crank axis and the motor axis, and
• a first line is defined that is arranged orthogonally to the longitudinal axis and tangentially on an outer circumference of the motor, and
• wherein the first fastening region has a first center point arranged on the first line or on a side of the first line facing away from the crank axis.
