A bottom bracket gearbox includes a crank axle and a gearbox output shaft. The crank axle is connected to a second element of the first planetary gear set and connectable to a third element of the second planetary gear set via a fourth shift element and a second shaft. The gearbox output shaft is connected to a first element of the first planetary gear set and to a first element of the third planetary gear set. A third element of the first planetary gear set is connected to a second element of the second planetary gear set via a first shaft. A first element of the second planetary gear set is connected to a second element of the third planetary gear set via a third shaft. Two elements of the third planetary gear set are connectable via a fifth shift element to interlock the third planetary gear set.
