This invention provides a tricycle having a simple frame that is shaped to provide an efficient low profile, lever actuation, which is adapted to be hand-operated for enjoyable, interesting and efficient training purposes, including efficient propulsion, and interesting and enjoyable arm-hand training and coordination. The frame also has low profile steering from a sitting or leg-outstretched position, which is comfortable, provides a low center of gravity and enhances the efficiency, enjoyment, training and coordination provided by the hand-operation. Still further, the frame is shaped to provide a strong, simple and effective coupling system for connecting more than one tricycle in a train for purposes of education, enjoyment, efficiency, training and coordination.
