Hi Kioshk, The motor is a 2 stroke 50cc ? type SM 1 made about 1954 by Sanki Ind Co Ltd and I believe the Miyata bicycle company had them made for their Miyata worker retro bikes to attach to the bikes pedal crank. I think this one is probable a one of a kind as it has the spring feather forks that I have not seen on other retro bikes here and perhaps was a showroom piece.
