The most important cities for me are Erlangen, Nuernberg and Tennenlohe.
Not so important for me is Munich.

Starting from Erlangen Suedgelaende I need 15 minutes to reach Tennenlohe with the bike.
But I need 20 minutes back to Erlangen. To travel to Nuernberg I whould prefer the train.
With the Train you need 30.5 minutes from Erlangen.
