The disclosure relates to a crank transmission assembly for a bicycle, comprising a crank housing; a primary axle associated with a primary axis; and a secondary axle offset from the primary axle and associated with a secondary axis. A first transmission is operative between a first transmission input rotatable about the primary axis and a first transmission output rotatable about the secondary axis. A second transmission is operative between a second transmission input rotatable about the secondary axis and a second transmission output rotatable about the secondary axis. The secondary axle is torque-supported by the crank housing only on one axial side of the first transmission output.
