I sold Miyata bikes in the mid 80's for about 4 years. As far as I remember, Mikado was their low end made in Taiwan entry level bikes that fell way below the Miyata 100 model. I got them from the same distributor in NJ that I sold Miyatas from. They were basic $150-175 bikes. This was a similar scenario to Raleigh having their Rampar line, Schwinn in the early 70's having the 'World' line, etc.
