1. A gear set arrangement (10) for a planetary gearbox of a bicycle, comprising:
a planetary assembly comprising an input (34), an output (36), and a planetary gear set (12) with a first rotary element, a second rotary element, and a third rotary element, the first rotary element is a sun gear (14);
a stationary component (24);
a first brake (B1);
a second brake (B2);
a first freewheel clutch (F1); and
a second freewheel clutch (F2),
wherein the first rotary element is rotationally fixable on the stationary component (24) by the first brake (B1), the first rotary element is connectable to the output (36) for conjoint rotation by the first freewheel clutch (F1), the second rotary element is rotationally fixable on the stationary component (24) by the second brake (B2), the second rotary element is connectable to the output (36) for conjoint rotation by the second freewheel clutch (F2), the third rotary element is permanently connected to the input (34) for conjoint rotation, and
wherein the gear set arrangement (10) is configured to provide three ratios between the input (34) and the output (36).
