Bikefriendly roads in northGermany and Denmark?

I´m planning to have a few long days riding, going back from France. Basically it´ll be a two-day creditcard tour with minimal packing trying to cover the last 500 k back home to Sweden. If it doesn´t rain. Then I´ll just stay in the car. I don´t do misery.

Anyway, any Germans or Danes out there that might share some good Internetsites on cyclingfriendly roads? Via Michelin is OK but I´ve noticed it to include gravelroads and not being very accurate…

My preliminary schedule is to ride from around Hamburg, through Denmark and over the bridge from Copenhagen into Malmö, alternatively, ride all the way up through Denmark to Fredrikshavn and get the ferry over to Gothenburg.
