A scooter is presented which allows the rider to maintain a secure forward facing stance with both feet parallel to the direction of travel and a combined center of gravity of both rider and scooter centrally between the front and rear wheel irrespective of the vertical tilt of the scooter. The scooter comprises a frame with high torsional strength, suitable for attaching an adjustable footrest thereto. The footrest may comprise two footrests, one on each side of the frame, or a footboard sufficiently wide to allow the rider to place both feet parallel to the direction of travel thereon. The longitudinal position of the footrests or footboard may be adjustable by selectively attaching the footrests or footboard to one of two or more attachment features at the frame.
