I've got an '81 Austro-Daimler Olympian that's still in project mode, as I am conflicted over putting a Shimano Arabesque group on it; Sachs/Huret seems a better choice. But the only German bike I've had pass through my garage was a cheapie - Mundo Cycles built in W. Germany. It had several stickers informing the rider that it was built to strict international standards that would comply with American requirements. It had a significantly damaged seatstay, I harvested a few parts and donated it to become a white "ghost" bike.
