A control system includes an electric motor, an electric storage device, a throttle grip, a brake lever, a controller, and an acceleration/deceleration adjustment lever. The controller supplies electric power from the electric storage device to the electric motor in response to an acceleration command input by the throttle grip and causes the electric motor to drive the rear wheel. The controller adjusts the electric power generated by rotational power applied by the rear wheel in response to an acceleration/deceleration command from the acceleration/deceleration adjustment lever. The acceleration/deceleration adjustment lever is provided separately from throttle grip.
