After the first World War Otto Feick, a railwayman, was imprisoned. Being arrested, he remembered an experience of his childhood, where he rolled down a hill in two barrel rings which were tied together. Then, Feick planned to build a gymnastic apparatus out of his childhood dream. In 1925 Feick patented the wheel and reserved all rights in 30 countries. Feick gave presentations in England, France and the USA supported by a group of selected gymnasts.
