The BET 3-wheeler was a light five-seat passenger car introduced in 1965 by Biotechnia Ellinikon Trikyklon (BET), a small Greek vehicle manufacturer. It used a BMW 125cc motorcycle engine. Although the type was certified, only one was built due to problems in availability of parts for further production. BET did produce, in small numbers, a number of other three-wheeler types, including trucks and a light passenger car introduced in 1973.
