An electric vehicle comprising: a steering device including first and second gripping members (5a, 5b) which are gripped by driver's right and left hands, respectively; an electric motor for driving a drive wheel; a throttle for activating the electric motor, wherein the throttle is provided at the first gripping member; a brake lever for activating a brake member for braking a front wheel, wherein the brake lever is provided in front of the first gripping member; an adjustment lever capable of being operated by a driver between a non-switched state and a switched state, wherein the adjustment lever is provided in front of the second gripping separately from the throttle and the brake lever, wherein the adjustment lever is pivotable from an adjustment lever reference position toward a driver by pulling the adjustment lever toward the driver with a finger of the driver's hand, wherein the adjustment lever is applied with a biasing force for returning the adjustment lever to the adjustment lever reference position, and wherein the adjustment lever is provided with a position sensor which is configured to output an adjustment command corresponding to a position with respect to the adjustment lever reference position; a controller for controlling an activated state of the electric motor in response to an operation of the throttle and the adjustment command; and a main switch provided separately from the adjustment lever to activate the controller, wherein when the throttle is operated in a state in which the adjustment lever is not operated and placed in the non-switched state, the controller activates the electric motor; wherein in a state in which the adjustment lever is operated and placed in the switched state, the controller does not activate the electric motor, even when the throttle is operated, wherein the controller transitions to a starting permission state when a predetermined starting permission condition is satisfied, in a starting stand-by state in which the electric motor is placed in a stand-by state; wherein when the adjustment lever is operated and placed in the switched state in the starting permission state, the controller maintains the starting permission state and does not activate the electric motor even when the throttle is operated; wherein when the throttle is operated within a predetermined time in a state in which the adjustment lever is not operated and placed in the non-switched state, the controller activates the electric motor; and wherein when the non-switched state of the adjustment lever continues for a predetermined time, the controller transitions to the starting stand-by state. a steering device including first and second gripping members (5a, 5b) which are gripped by driver's right and left hands, respectively;
