A drive train for a vehicle with a pedal drive with a bottom bracket shaft (1) of a crank drive, which comprises a first planetary gear (8, 9, 10) shiftable by clutches, the output of which is connected by a traction means to a rear wheel gearbox comprising a further gearbox shiftable by second clutches, wherein these two gearboxes are each to be shifted in such a correlated manner that gear transitions are approximately the same overall, characterized in that, in a first shift position, the bottom bracket shaft (1) is directly connected on an output side to a traction drive (ZG) by the first planetary gear (8, 9, 10) and/or, in addition, an auxiliary electric motor (EM) is connected by the planetary gear (8, 9, 10) to the traction drive (ZG) and that the gear transition of the first planetary gear (8, 9, 10) comprises each all finer-stepped gear transitions of a further gearbox (NG) arranged downstream via the traction drive (ZG) and/or in a second shift position of the planet carrier clutches and the sun gear wheel clutches (KPT, KSR) of the first gearbox, the auxiliary electric motor (EM) is coupled directly to the output shaft (3) via the reduction gearbox and further the bottom bracket shaft (1) is coupled to the output shaft (3) via this first planetary gear (8, 9, 10).
