An articulated electric bus includes two units with: a passenger compartment including a main floor forming a low and thin platform with a planar surface extending over the majority of the width of the passenger compartment, a wheel housing adjacent to the planar surface, a longitudinal row of seat places on the wheel housing, and a driving wheel which is housed in the wheel housing under the longitudinal row of seats. The driving wheel defines a rotation axis and includes an electric engine, and a rim with a rim top above the planar surface. The driving wheel is vertically movable with respect to the planar surface, and the wheel housing actually receives a pair or a couple of driving wheels.
