A cart or conveyance for a person uses a two wheeled electric hoverboard as a drive unit. A clamp is positioned about the center of the hoverboard to enable the hoverboard to be retained by the clamp while remaining rotatable within the clamp. The clamp is hitched to a drawbar, which is in turn connected to an axle supporting two wheels. A seat is attached to the drawbar and axle, and positions a rider to place their feet upon the hoverboard in order to operate the hoverboard.

A tandem rider device and method of use for maintaining three planes of stability, elimination of interference and steering is presented. In particular, the present invention relates to devices and mechanisms, which when connected to the three planes of stability, vertical, horizontal and axial, between two duplicate personal transportation devices or between the transportation device and another device including structural stability elements provide for the following three enhancements. Provide tracking wheels, levers, springs and pedals for interference elimination devices allowing removal of tracking wheel interferences when two devices are connected together. Providing steering mechanism used for steering two duplicate personal transportation devices or steering the transportation device and another device when the tandem rider device is placed on a suitable surface other than parallel tracks. Providing a plurality of assemblies, that when such assemblies are removed, allow engagement of the steering mechanism when the transportation devices are removed from parallel tracks.
