A one-wheeled vehicle includes electric motors, a self-balancing system, and steering mechanism, wherein the electric motors and self-balancing system are disposed within the wheel of the one-wheeled vehicle. Side stirrup legs, which have foot pegs suitable for placement of a rider's feet while riding, are pivoted with respect to the wheel forks, such that the side stirrup legs may be rotated backwards and act as a kickstand for the one-wheeled vehicle. The side stirrup legs may be weighted with, for example, one or more batteries may be attached to the side stirrup legs to provide a weight distribution such that the one-wheeled vehicle does not fall forward when parked. A computational resource such as a microcontroller, or microprocessor-based controller, receives input signals indicative of operation of the twist throttle and brake, and responsive thereto produces signals to adjust the tilt angle relative to the acceleration and thereby reduce the need for a rider to lean forward or backwards.
