A bottom bracket planetary gear mechanism for a bicycle or a pedelec includes a gear mechanism shifting group having first and second planetary gear sets and first, second, and fifth shifting elements. A second element of the first gear set is connected to a first shaft, a first element of the first gear set is connected via a fourth shaft to a first element of the second gear set, and a third element of the first gear set is fixable via a second shaft and a first shifting element. The third element of the first gear set is connected via the second shaft to a second element of the second gear set. A third element of the second gear set is fixable via a third shaft and a second shifting element. A fifth shifting element blocks the first and second gear sets.
