The company was founded by Andries Gaastra in 1974, who had left his function at his father’s company Batavus. The name Koga is a combination of his surname and that of his wife Marion Kowallik. The addition of Miyata came from the cooperation with Japanese manufacturer Miyata.. Miyata started with the use of Japanese components of Shimano. The design and assemblage of the bicycles was done by hand in the Netherlands. At first Koga Miyata only produced racing bicycles. In 1976 they added a range of randonneurs or touring bicycles, and in 1986 mountain bikes.
