The invention relates to a bottom bracket transmission with a planetary design for a bicycle or a pedelec (1) comprising a pedal crankshaft (Wan) as a drive and a transmission output shaft (Wab) as an output, as well as at least four further shafts (W1, W2, W3, W4), at least three planetary gear sets (RS1, RS2, RS3) arranged coaxially relative to the pedal crankshaft (Wan), and at least five shift elements (B1, B2, B3, F1, F2, F2', F2") for implementing at least six gears (V1, V2, V3, V4, V5, V6), wherein the pedal crankshaft (Wan) is connected to a second element of the first planetary gear set (RS1), wherein the pedal crankshaft (Wan) can be connected to a third element of the second planetary gear set (RS2) via a fourth shift element (F1) and a second shaft (W2), wherein the transmission output shaft (Wab) is connected to a first element of the first planetary gear set (RS1) and to a first element of the third planetary gear set (RS3), wherein a third element of the first planetary gear set (RS1) is connected to a second element of the second planetary gear set (RS2) via a first shaft (W1), wherein a first element of the second planetary gear set (RS2) is connected to a second element of the third planetary gear set (RS3) via a third shaft (W3), and wherein two elements of the third planetary gear set (RS3) can be connected to one another via a fifth shift element (F2, F2', F2") in order to block the third planetary gear set (RS3).
