The invention relates to a bicycle gearing, comprising: a cylindrical-gear gearing (10), which has a stationary sun gear (11) having a central bearing axis (y1) extending centrally therein and a planet gear (12), which travels on the sun gear (11) and rotates about a planet-gear bearing axis (y2); a four-bar linkage (20), which interacts with the cylindrical-gear gearing (10) and which comprises a crank (21), which is fixedly connected to the planet gear (12) and is rotatably connected to a pedal crank (22); and a toothed wheel (30), by means of which a traction means (31) can be driven. The problem addressed by the invention is that of improving a bicycle gearing of the type in question in such a way that a rounder pedaling feel is perceived by the bicycle rider. The problem is solved according to the invention in that the toothed wheel (30) has an oval shape.
