10. Velorex Oskar
Built in Czechoslovakia, in the ’50s, the Velorex Oskar was one of the strangest cars ever to be produced behind the Iron Curtain. A motorcycle company produced it, so it was kind of a three-wheeled bike more than a real car.

It was powered by a 300 ccm motorcycle engine with 6 HP, and since the car itself was extremely light, this tiny motor even produced some performance as well. Interestingly, the Velorex didn’t have body panels, but canvas stretched over the frame rails.
