The present invention relates to a bicycle bearing driving device for a bicycle comprising a pedal crankshaft for operation by a rider; a transmission assembly disposed on the pedal crankshaft and including a plurality of planetary transmissions connected to each other; The shifting slide plate is arranged in a torque-proof manner of the pedal crankshaft, and the shifting slide plate is movable along the axial direction of the pedal crankshaft, wherein the sun gear of the planetary transmission has a shifting finger respectively, and the shifting finger refers to the pedal The crankshaft extends radially outward, wherein the shifting slide has a blocking element, wherein the blocking element overlaps with the at least one shift finger in the radial direction of the pedal crankshaft, so that the shifting is made by shifting the shifting slide The overlap of the finger and the latching element in the axial and radial directions of the pedal crank prevents the single or multiple shift fingers from rotating about the pedal crank.
