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.
