In Copenhagen we have free city bikes. Tourist loves them even though you sit very poorly.
Free wheeling is a new meditative exercise I can highly recommend.
It’s very simple you go on your bike put on your favourite playlist on the IPod (or your Discman if you’re an old school’er) you constantly drive the opposite direction of the road you know. You’ll find yourself in places you have never seen before with the world just passing by in the most relaxing way.
