Biotechnia Ellinikon Trikyklon was founded in Athens by Petros Konstantinou who converted BMW and other motorcycles into light utility three-wheelers.
In 1965 the firm designed and built a small five-seat passenger car with a BMW 125cc motorcycle engine. Only one was built, but this was followed by three-wheeled commercial carriers. A second passenger car model was introduced in 1973, the Model 500 with a Fiat 500cc engine. The car seated 5 people and was well received - 15 were built, of which one survives.
Production ceased in 1975.
