Abstract: A device, system, or method for changing the center of gravity of a bicycle, in particular an electric bicycle, to suit the situation, with: an actuator for changing the center of gravity of the bicycle, at least one sensor that monitors the riding status of the bicycle, a control unit which receives and processes data from the sensor, determines a center of gravity of the bicycle adapted to the situation and outputs corresponding control signals to the actuator in order to carry out the change in center of gravity. According to the invention, an adjustment speed of the change in the center of gravity can be adapted to a riding state of the bicycle.

Abstract: The invention relates to a gas pressure spring (50) comprising a working piston (2) which is guided displaceably in a working cylinder (1) along a stroke axis (H), a compensating cylinder (12) which encloses the working cylinder (1), and a compensating piston (10) which is of hollow-cylindrical shape and is guided displaceably in the compensating cylinder (12) along the stroke axis (H). The working cylinder (1) has an open end (1b), at which the compensating cylinder (12) forms a projection (15) beyond the working cylinder (1) with a closed end (15b). The compensating piston (10) separates a working chamber (1a) which is arranged in the working cylinder (1), a compensation chamber (12a) which is arranged between the working cylinder (1) and the compensating cylinder (12), and a restoring chamber (15a) arranged in the projection (15) from one another and is open at an upper side (10a) of the balancing piston (10) facing the working chamber (1a). The gas spring (50) comprises a seal (8) arranged on the upper side (10a) of the balance piston (10) which seals the balance piston (10) to the working cylinder (1) and to the balance cylinder (12).

Abstract: A damping system is provided including at least one fluid damper including a damping volume containing a damping fluid, and a fluid reservoir including a reservoir piston partitioning an inner volume of the fluid reservoir into a damping chamber containing the damping fluid and a recoil chamber containing a recoil fluid. The damping volume of the at least one fluid damper is connected to the damping chamber of the fluid reservoir in a fluid-conducting manner. The reservoir piston is movable in a compression direction increasing a volume of the damping chamber and decreasing a volume of the recoil chamber. The reservoir piston is movable in a dilatation direction decreasing the volume of the damping chamber and increasing the volume of the recoil chamber. The reservoir piston includes a damping chamber surface facing the damping chamber and a recoil chamber surface facing the recoil chamber.

Abstract: A gas pressure spring is provided including a working piston which is guided displaceably in a working cylinder along a stroke axis, a compensating cylinder encloses the working cylinder, and a compensating piston which is of hollow-cylindrical shape and is guided displaceably in the compensating cylinder along the stroke axis. The working cylinder has an open end, at which the compensating cylinder forms a projection beyond the working cylinder with a closed end. The compensating piston separates a working chamber, which is arranged in the working cylinder, a compensating chamber, which is arranged between the working cylinder and the compensating cylinder, and a restoring chamber, which is arranged in the projection from one another. A distance, radially with respect to the stroke axis, of the compensating cylinder from the working cylinder is greater in the stroke range than in an end region of the working cylinder.
