A gear set arrangement () for a bicycle gearbox () includes a planetary assembly, a stationary component (), a first and a second brake (B, B), and a first and a second freewheel clutch (F, F). One planetary gear set () of the planetary assembly includes a first rotary element, a second rotary element, and a third rotary element. The first rotary element is rotationally fixable on the stationary component () by the first brake (B). The first rotary element is connectable to the output () by the first freewheel clutch (F). The second rotary element is rotationally fixable on the stationary component () by the second brake (B). The second rotary element is connectable to the output () by the second freewheel clutch (F). The third rotary element is connected to the input () for conjoint rotation. The gear set arrangement () is configured to provide three ratios.
