Saddle-riding type vehicle with a simplified battery removal system

A saddle-riding type vehicle comprising:

• a frame extending mainly along a longitudinal direction and comprising a front portion, a central portion, and a rear portion;
• the front portion supporting a front-end part that comprises a steering assembly pivotably connected to the front portion of the frame to control at least one steered wheel of the vehicle;
• the rear portion supporting a rear-end part that comprises a saddle and at least one driving wheel arranged below the saddle;
• the central portion supporting an intermediate part connecting the front-end part to the rear-end part;
• a powertrain connected to the frame and comprising at least one electric motor operatively connected to the at least one driving wheel;
• an electrical power supply assembly configured to power the electric motor for 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;
• wherein each battery is supported by a corresponding first support or second support, each of the first support and second support movable between a retracted position and an extended position;
• and
• moving means for causing simultaneous rotation of the first support and second support around a corresponding axis of rotation so that the first support and the second support occupy the retracted position or the extended position.
