Cyklonetka

Cyklonetka was a prototype three-wheeler cyclecar designed in 1939 by brothers Eugeniusz, Jan, and Wacław Knawow in their workshop in Kielce, Poland.

History
Cyklonetka was designed by a team of brothers: Eugeniusz, Jan, and Wacław Knawow in their workshop in Kielce, Poland. The brothers manufactured all elements of the car, but the engine, in their workshop. The engine was manufactured in the Steinhagen-Stransky factory in Warsaw. In summer of 1939, the brothers had traveled with their car, equipped with the bike registration plate, to Warsaw, where they met with Antoni Roman, the minister of industry and trade, who was impressed with their car, and commented that the vehicle should have car registration plate instead. Soon after that, Nazi Germany had invaded Poland, beginning the World War II, which made it impossible for the future development of the car.

Specifications
The cyclecar was a convertible three-wheeler cyclecar with a 98cc moped engine, which was manufactured in the Steinhagen-Stransky factory in Warsaw.
