A personal conveyance is herein disclosed wherein a space frame of roll cage of an integral passenger and engine compartment is fabricated from at least two , preferably elliptical, roll bars (1, 2 and 3) that are directly or indirectly associated with a floor pan. In each case, at least one roll bar is integral with and supportive of the perimeter of the floor pan and preferable permanently bonded thereto. A second roll bar is then arranged inboard of the horizontal roll bar, in a linear array along the length of the vehicle, and at an inclined angle relative to the plane of the floor pan. The horizontal roll bar is affixed to the inclined roll bar at each point of intersection (6) or coincidence thereof, so as to form an essential unitary structure or roll cage sufficient to accommodate both passenger and power plant compartments.
