Like anywhere, it will depend on whether you are talking city or country. I had a bike stolen from outside my office in Frankfurt, and I did all sorts of tours round rural France and Germany without any problems. I even left my fully loaded bike in town squares with a single cable lock on numerous occasions, and it was there each time when I got back. I think it's all about luck, and whether the Gods are smiling or frowning that day.
