- the micro-mobility vehicle 1 has a front wheel and a rear wheel.
- the main drive device 2 acts on the rear wheel of the micromobility vehicle 1 .
- the main drive device 2 has a first electric motor 7 . Furthermore, the main drive device 2 has a harmonic drive 12 which is operatively connected to the first electric motor 7 . The torque made available by the first electric motor 7 is thus translated by means of the harmonic drive 12 .

- the control device 6 then controls the power take-off device 3, more precisely the second electric motor 8, so that it is activated and provides the additional power requirement.
- the micromobility vehicle 1 also has the energy storage device 9 .
- This is connected in an energy-efficient manner to the first electric motor 7 and to the second electric motor 8 . These connections are wired. Both the first electric motor 7 and the second electric motor 8 can be supplied with energy by the energy storage device 9 .

- a charge level of the energy storage device 9 can be forwarded to the control device 6 via a signal-effective connection between the energy storage device 9 and the control device 6. This allows the control device 6 to control whether the power take-off device 3 should recuperate energy when the charge level is correspondingly low.
- the user of the micromobility vehicle 1 can use the button 5 to request an additional power requirement for the propulsion of the micromobility vehicle 1, in addition to the propulsion that is already being accomplished by the main drive device 2 and possibly by the muscle power of the user himself.
