PS.SPEICHER is Einbeck's strongest single attraction: a transport museum in a restored granary, with motorcycles, cars, microcars, commercial vehicles, and changing exhibitions spread across several sites. It is not just a line of polished old machines; the main exhibition does a good job of tying mobility to everyday life.
Allow more time than you think if historic vehicles interest you. The museum is large enough to carry the day for enthusiasts, and still worthwhile for casual visitors because the building and displays are unusually well presented.
