The sign on the right warns that the cycleway is damaged, and indeed it is. The damage is probably thermal (not being surrounded by sea, it can get both very hot and very cold in Germany). However, whilst the cycleway is indeed a bit bumpy, it's not as bad as parts of NCN5 through South Birmingham. In a country where it is normal for asphalt to be absolutely trashed, signing would be a herculean task. You can also see that the carriageway has been patched. However, there are no suspension-destroying holes on this relatively major road (that would probably be classed as a B road in the UK).
