Abstract: A wheeled carriage for recreational purposes comprising a platform large enough for a person to stand on with his or her feet side by side, and a single front wheel and a single rear wheel mounted to said platform so as to be capable of rotation about spaced parallel axes and with the centers of the wheels lying in the longitudinal vertical central plane of said platform, the wheels being of rounded profile to enable the platform to tilt laterally in use, the platform being offset above or below the axes of the wheel, whereby the carriage can be used either way up, the platform being above the wheel axis when the carriage is one way up so as to require a high level of skill to maintain the carriage balanced, and the platform being below the wheel axes when the carriage is the other way up so as to require a lower level of skill to maintain the carriage balanced.
