Wehrmacht sidecar gymkhana

A card from a packet of Eckstein Nr 5 cigarettes, a German brand around since 1854 and apparently still going on unfiltered as ever. The series was entitled 'Die Deutsche Wehrmacht' and this image of a motorcycle gymkhana seems innocent enough but the set was produced in 1936 and was undoubtedly propaganda for the growing Nazi war effort. Can anyone identify the bike?
