At the same time, BMW sought to offer a more affordable car. Motorcycles were BMW's largest money earner at the time, and their sales had peaked in 1954. Germans were turning away from mopeds and motorcycles toward light automobiles such as the Messerschmitt KR175 and the Goggomobil. After seeing the Iso Isetta bubble car at the 1954 Geneva Motor Show, BMW entered talks with Iso Rivolta and bought both a licence to manufacture the Isetta and all the tooling needed to manufacture its body. Production of BMW's version of the Isetta began in 1955; more than ten thousand Isettas were sold that year. BMW made more than a hundred thousand Isettas by the end of 1958, and a total of 161,728 by the end of production in 1962.
