Gear arrangement for a vehicle, in particular for a vehicle which can be driven using muscular force, such as a bicycle. The gear arrangement has a housing, an input shaft, layshaft, an output shaft which can be connected to a drive wheel of the vehicle. A plurality of shiftable first gear wheel sets connect the input shaft and the layshaft and are each associated with at least one gear stage. A machine gear which is connected or can be connected to one of the shafts and into which the drive torque of an electric machine can be introduced. The first gear wheel sets form a first part-gear mechanism, wherein at least one second shiftable gear wheel set connects the layshaft and the output shaft and forms a second part-gear mechanism. The at least one second gear wheel set is associated with at least one gear stage. The housing defines a cooling fluid sump.
