Abstract: A bicycle has a main frame, a rear suspension having a spring and guiding a wheel along a prescribed path and an electric drive mounted on the main frame. A driving pinion thereof being is disposed coaxial to the shaft of a bottom bracket, and at least one driven pinion is disposed coaxial to the rear wheel and operationally connected to the driving pinion of the electric drive by a chain. A chain segment transmitting torque from the driving to the driven pinions is guided by a chain deflector. A distance between where the chain segment engages the driven pinion and the point of the chain deflector about which the chain is substantially pivoted when the wheel is deflected changes so slightly that the crank arms of the bottom bracket rotate by a maximum permissible angle relative to a non-deflected position of the wheel when the spring is deflected.

Abstract: An insert is removably fastened in an opening on a bicycle frame for securing cables, cable pulls, or lines routed through the opening. The insert includes a pass-through opening for the cable, the cable pull, or the line. The insert includes at least one thrust block to be inserted in the opening, by which the insert is supported in the region of the opening on the inner side of the bicycle frame after being inserted in the opening. The insert is removably fastened by at least one fastening element disposed at a distance from the thrust block such that the insert makes sealing contact at least in segments under pre-tension due to the interaction of the fastening element with the thrust block in the edge region transitioning into the peripheral contour of the underside of the insert facing the bicycle frame.

Abstract: The invention relates to a bicycle frame made of fiber-reinforced material, particularly of plastic reinforced with carbon fibers, having a rear wheel suspension for supporting the rear wheel. According to the invention, a receptacle is formed on at least one of the two chain stays of the rear wheel suspension, in which a replaceable adapter plate adapted to the hub of each rear wheel to be used is removably fastened, in which the axle of the rear wheel can be supported.
