No. We also occasionally make use of walking, canal tour boats, public water busses (for smaller groups), the metro, private coach tours or a combination. We prefer bikes for transportation because it's by far the faster transportation in Copenhagen, it facilitates the largest possible range, and the most dynamic and flexible route planning with more variation and more stops. Besides that, cycling is so fundamental to life in Copenhagen, so it's half the cultural experience and a profound mind changer for most visitors. But - sometimes, for some reason, cycling is just not an option. And, after all, that alone should not rule out a great Copenhagen exploration.
