The invention relates to a planetary center shaft transmission for a bicycle or an electric moped, comprising a pedal crankshaft (WAn) as input and a transmission output shaft (WAb) as output, and comprising further shafts (W1, W2, W3, W4, W5, W6, W7), and comprising a first transmission shift group (3) and a second transmission shift group (4), the first transmission shift group (3) and the second transmission shift group (4) are coupled to each other in order to achieve a plurality of transmission ratios (G1, G2, G3, G4, G5, G6, G7, G8, G9, G10, G11, G12), in which the first transmission shift group (3) comprises a two-step planetary gear set (StRS), to which a first shift element (B1), a second shift element (B2) and a fifth shift element (F1I, F1II, F1III, F1IV, F1V, F1VI) are assigned. A bicycle or electric moped (1) having a centre shaft transmission is also proposed.
