I thought it was having unclassified roads get road_class 0. But to be
honest: I never tested. I just rely on r1430 for my bicycle maps. Then
again, when I cycled from Copenhagen to Amsterdam this summer, I used
the regular maps and they worked pretty well - in Denmark and Germany,
that is. So most likely it has something to do with the density of
bicycle roads, combined with the road class changes.

So please ignore my comments for now - if I have time, I'll try to test
a more fine grained r1430-1431 change and report my findings.
