Abstract: A method is provided for charging a battery-operated vehicle having a chargeable traction energy store and a system for autonomously guiding the vehicle with a charging vehicle having an energy generator and/or an energy store. The method forms at least one electrical coupling between the battery-operated vehicle and the charging vehicle via an autonomous driving manoeuver of the battery-operated vehicle and/or the charging vehicle. A charging of the traction energy store of the battery-operated vehicle occurs via the energy generator and/or the energy store of the charging vehicle during the driving of the paired battery-operated vehicle and charging vehicle.

Abstract: A control device for a scooter and a scooter for transporting individuals are provided. The scooter is operable using physical strength in a first mode of operation while being operable using physical strength and/or electric power in a second mode of operation. The scooter has an operating device for a control unit, and an electric motor which allows the scooter to be powered. A propulsive force is created on the scooter by actuating the operating device.

Abstract: A single-track scooter for transporting people is provided. The scooter includes a front wheel and a rear wheel (arranged one behind the other in the longitudinal direction of the scooter, a fork for holding and guiding the front wheel, a rear wheel mount and a frame formed in three parts. The frame includes a fork mount, a middle part and a rear wheel mount. The fork mount can rotate relative to the middle part about a first axis of rotation and the rear wheel mount can rotate relative to the middle part about a second axis of rotation, with the axes of rotation being arranged at an acute angle to the longitudinal axis of the scooter.

Abstract: A frame assembly is provided for a two-wheeled vehicle, in particular for a bicycle, including: a main frame, which has a head tube for connecting to a front wheel mount and a saddle connection for connecting to a saddle; and a drive-train swing arm pivotably connected to the main frame. The drive-train swing arm includes a wheel suspension for a rear wheel to be driven and a pedal-crank drive having a pedal crank for driving the rear wheel by muscle force of a rider. The pedal-crank drive is associated with the drive-train swing arm. The drive-train swing arm is pivotably connected to the main frame by a multijoint assembly.
