Yesterday my father's friend sent me a manual of a 1921 Cyklonette. It was built by the Cyklon Maschinenfabrik in Berlinand and Mylau. The engine had 2 cylinders and 10hp. It was quite successful especially before WW1. In my eyes the engine in the visual field would bother me.
An interesting machine there, you would need arms like popeye to steer it though. Love the 2 leaf springs on the front axle. Morgan cart spring engineering at it's finest.
