A one-wheeled vehicle may include 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. A computational resource such as a microprocessor-based controller receives input signals indicative of operation of a twist throttle and brake, and produces signals to adjust the tilt angle relative to the acceleration and thereby reduce the need for a rider to lean forward or backwards.
