Abstract: An electric small-sized vehicle, in particular an electric scooter, having a rear wheel, a frame, a support with a foot board and a wheel folding mechanism. The support includes a rear support section connected to the rear wheel, a front support section connected to the frame, and a receiving area for the rear wheel. The wheel folding mechanism has a first joint with a first pivot axis. The vehicle is adjustable from an unfolded position into a folded position via the joint. The front support section is connected to the rear support section by the first joint. In the unfolded position, the rear wheel is positioned in an outer position where the rear wheel is arranged outside of the receiving area, and in the folded position, the rear wheel is positioned in an inner position where the rear wheel is at least partly arranged within the receiving area.

Abstract: A vehicle, such as a cargo cycle, may have a multi-part frame, a single wheel and a wheel pair having two mutually spaced wheels. The single wheel may be connected to a first frame part of the frame, and the two wheels may be rotatably mounted about a common axis on a second frame part of the frame, where the first and second frame parts are connected with at least one joint and are rotatable relative to each other about a pivot axis defined by the at least one joint, the pivot axis running through a contact point of the single wheel. The vehicle also has at least one first drive device which generates a torque, is arranged on the first frame part and is designed to transmit the torque via a device for torque transmission to at least one of the wheels of the wheel pair.

Abstract: A vehicle, such as a cargo bike, may include a multipart frame, a single wheel, and a wheel pair which comprises two mutually spaced wheels, where the single wheel is connected to a first frame part of the frame, and the two wheels of the wheel pair are rotatably mounted on a second frame part of the frame about a common axis. The first frame part and the second frame part may be connected by at least one joint and can be rotated relative to each other about a pivot axis defined by the at least one joint, and the pivot axis may run through a contact point of the single wheel.

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 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.
