With the end of World War I in 1918, BMW faced problems related to the economy and the reduction of military orders. As a result, the company was forced to diversify its business, and in 1920, the transition to the production of motorcycles and cars began. In 1923, BMW released its first motorcycle, the R32, which was revolutionary. The motorcycle was distinguished by a horizontally mounted engine and a robust design.
The success of motorcycles inspired BMW to take further steps. In 1928, BMW bought the Eisenach Motorenwerk company, which allowed it to enter the passenger car market. Then in 1929, the first passenger car was released - the BMW 3/15, which became the basis for further development of the automobile direction. It was a compact and economical car that was able to win the sympathy of consumers.
