Berlin is a great city for biking. Particularly in summer, you can get just about anywhere you want by bike. An extensive network of bike paths are generally marked by red pavement or white markings on the sidewalks (when you’re walking, try to avoid walking on bike paths if you don’t want to have cyclists ring their bells at you). Many stores that rent or sell bikes carry the Berlin biker's atlas, and several places offer terrific bike tours of the city.
