>>1476241>>1476316P.S. for Germany specifically, I'd recommend buying a cycling map. The cycling trails in Brandenburg & MV are excellent and they have tons of signs and signals. But the map is nice, telling you about every shop and restaurant, ever castle or historically important place and hidden nudist camp ground on the route.
The Berlin-Rostok bit and the Berlin-Usedom bit are especially nice, and the whole stretch on the MV coast is great, Greifswald, Stralsund, Wismar, that bit.
