I've categorized the "Road Rebel" as a racing car although it is not really recognizable as any such thing. Still, it seems closer to that than any regular car. With a single cylinder engine and yet, oddly, dual exhaust, this is a true enigma. The 1 stud wide seat looks particularly uncomfortable.
Engine
This model has a single cylinder reciprocating engine. The crankshaft is also used as a solid rear axle giving a permanent 1:1 gear ratio.
