1. A method for operating an electric vehicle comprising:
determining if at least one of a speed of the vehicle and a speed of an electric motor of the vehicle is zero;
in response to the at least one of the speed of the vehicle and the speed of the electric motor being zero, determining if a reverse actuator is actuated, the reverse actuator being mounted to a first handle of a handlebar of the vehicle;
in response to the reverse actuator being actuated, starting a timer;
once the timer has started, determining if the reverse actuator has been actuated without interruption for a predetermined amount of time determined by the timer;
in response to the reverse actuator having been actuated without interruption for the predetermined amount of time, changing an operation mode of the electric motor, the operation mode being one of a forward mode and a reverse mode, changing the operation mode of the electric motor comprising:
changing from the forward mode to the reverse mode, in response to the motor being in the forward mode prior to the reverse actuator being actuated; and
changing from the reverse mode to the forward mode, in response to the motor being in the reverse mode prior to the reverse actuator being actuated;
after changing the operation mode, actuating an acceleration input device, the acceleration input device being an acceleration lever mounted to a second handle of the handlebar of the vehicle; and
in response to actuating the acceleration input device, operating the electric motor in the operation mode.
