Apparatus including operation-switch assembly for switching propulsion operation of vehicle

An apparatus for a user and for a vehicle being configured to support the user, the apparatus comprising:

• an operation-switch assembly being configured to be supported by the vehicle, and the operation-switch assembly also being configured to switch propulsion operation of the vehicle between a first propulsion-operation mode and a second propulsion-operation mode;
• in the first propulsion-operation mode, the operation-switch assembly also being configured to permit propulsion of the vehicle to be influenced by a power-train assembly being configured to generate a power-train force;
• and
• in the second propulsion-operation mode, the operation-switch assembly also being configured to:
• permit propulsion of the vehicle to be influenced by a non power-train force;
• and
• permit propulsion of the vehicle to be not influenced by the power-train force of the power-train assembly;
• and
• a wheel assembly being configured to operatively couple to the vehicle in such a way that the wheel assembly transmits a torque force that facilitates rolling movement of the vehicle relative to a surface;
• and
• the operation-switch assembly including a friction-gear assembly being configured to operatively couple to the power-train assembly in such a way that the power-train assembly rotates the friction-gear assembly once operated;
• and
• wherein:
• the wheel assembly includes:
• a first wheel assembly;
• and
• a second wheel assembly being spaced apart from the first wheel assembly;
• and
• the friction-gear assembly includes:
• a first friction gear;
• and
• a second friction gear being spaced apart from the first friction gear;
• and
• the power-train assembly includes:
• a first electric motor being configured to drive the first wheel assembly via the first friction gear;
• and
• a second electric motor being spaced apart from the first electric motor, and being configured to drive the second wheel assembly via the second friction gear.
