Zundapps.com is a resource which documents the rise and fall of the Zündapp motorcycle brand during the pre-war and inter-war years 1930-1945. While Zündapp survived World War II, it was never able to regain its prior seat amongst the world's large motorcycle manufacturers. Now defunct, Zündapp is alive still in the community of entusiasts who keep these great machines on the road.

Zundapps.com attempts to document each of the early Zündapp models and host a registry of all known machines that exist today.
