Ott was a four-wheeled light car of 1949, built by Jaroslav Ott of Prague. It carried two or three people under a closed, self-supporting aluminium body with doors that hinged upward. A Jawa 250 engine sat at the rear, and the wheels had 16 x 4" tyres and mechanical brakes. The body had no bonnet, which kept the car to 2,000 x 1,300 x 1,185 mm and 230 kg.
