Conceived and marketed as a “car on two wheels”, the Mobil had body panels that enclosed the drivetrain, protected its riders from the elements, and included an integral pair of panniers and a mount for a spare tyre.

[1][2] Mounted on the fairing were a transparent plastic windscreen that wrapped around the handlebars, a dashboard through which the steering column protruded,[1][2] and lower panels containing a glovebox and provision for a car radio to be installed.

[2] The Mobil originally had a 150 cc single-cylinder two-stroke engine[1] mounted between the dashboard and the rider's seat.

[1][2] Access panels on both sides of the Mobil could be removed to work on the engine.

Power was transmitted through a three-speed transmission operated by a twist grip.
