Not OP, but I live in Munich and have heard of both six-week and one-day waiting times this summer. It depends on part availability. One day is common, six weeks not unheard of. A friend waited almost that long when two strange and unusual screws had to be replaced, the wrong ones arrived from the manufacturer, etc. The quick routine procedures failed her, the result was slow.

Just from what I hear, it seems that there are more cases of unavailble parts this summer than a few years ago. Maybe the supply chains haven't quite settled after covid, even now.

The person who mentioned six weeks didn't specify whether Van Moof has a six-week average or whether it's a 99th percentile.

There are three within 5 minutes on my bike. But waitlists for appointments are crazy in the summer. My friends don’t cancel but pass them on amongst each other if they don’t need theirs.

In Hamburg and London, bike shops absolutely have six week backlogs.
