Publication number: 20230104952Abstract: A bicycle includes a transmission having two switchable drives between a driver body on which rear sprockets are positioned and a wheel hub of a rear wheel. The bicycle has actuation elements for switching between drives and operating elements for operating the actuation elements. The bicycle includes only a single front sprocket. The actuation elements are embodied in an electrical version and the operating elements are electrically coupled to the actuation elements. By advantageously selecting the drives of the driver between the cassette housing and wheel hub, a front derailleur may be omitted.
