At the end of the First World War, the automotive industry builds on the technological expertise derived from arms manufacture. Room 2 is devoted to imaginative designers and their machines. Legendary motorcycles such as the Weisse Mars, Neracar, Wanderer 500 and BMW R32 epitomise unconventional styling and technical innovation. In the post-war years, the motorbike is the only affordable entry-level vehicle for enthusiasts. Motorcycles become the first popular mode of motorised transport in the 1920s, allowing their owners a greater radius of travel. Different types of vehicles from the Roaring Twenties set against a contemporary street scene show the level of motorisation in this era – including a Horch 350, a Hanomag Komissbrot and various bikes with or without auxiliary motor.
