The electric motor, the battery, and the control unit are disposed on the swing arm. The swing arm integrally provides, forwardly of a rear wheel, a bulkhead for accommodating a battery in isolation from an electric motor and a control unit. The bulkhead has an opening portion that faces terminals disposed on the battery. A battery accommodating portion integrally provides a partition wall extending in a vehicle width direction to form a plurality of accommodating chambers with each containing one of a plurality of batteries. A stand disposed downwardly of the partition wall is supported rotatably on a bottom wall of the battery accommodating portion. ## Claims ### Claim 1 A saddle riding, electric vehicle comprising: a swing arm removably and vertically swingably supported on a vehicle body frame;
