A saddle-riding type vehicle comprises a frame extending mainly along a longitudinal direction and comprising front, central, and rear portions. The vehicle comprises a powertrain connected to the frame and comprising at least one electric motor operatively connected to at least one driving wheel. The vehicle also comprises an electrical power supply assembly for powering the electric motor to allow the traction of the vehicle and comprising at least one first pair of batteries arranged on opposite sides with respect to a longitudinal center plane of the vehicle, orthogonal to the axis of rotation of the at least one driving wheel. Each battery is supported by a corresponding support movable between retracted and extended positions, each support being operatively connected to moving means which releases and/or causes the rotation of the support itself around a corresponding axis of rotation to allow the supports to reach the extracted position.
