One of the best way to discover Berlin is to cycle a bike.
It's flat - it's a lot of nature.
Unfortunately the German Law does not allow riding on the walkways - unless there is a own lane for bikers.
Berlin bikers mostly ignore the law and subject you are not too slow you can go also on the street. If you are from New York City and you financed your highschool by a job as bike courier you are best qualified to cycle in Berlin.
The others: do not worry - just follow one rule: do not try to understand the German law how to make a left turn on a bike. Just get off and push your bike to the other side of the streets. Make a left turn as cyclist is like a survival training...
Train station Friedrichstraße is your station.
It's one stop by commuter-train (S-Bahn) from Hauptbahnhof (Central Station).
All trains from platform 15 are going for Friedrichstraße. It's one stop.
Subject you came by car but left it outside the city center in the shopping mall Am Borsigturm then you get off from the subway U6 at Friedrichstraße as well.
All you need to find is this exit towards Georgenstraße.
You turn to the right and walk to Reichstagsufer (the bank to Reichstag alongside the river Spree).
And there you'll find this bike as sign to find the bike-rental-place.
Hard to identify.
The prices and they accept credit cards.
And the opening hours.
So if you stand opposite of the bike-rental-place you can just watch to the train station Friedrichstraße.
Do not forget to return the bike before you return to Warnemünde.
