I'm curious about this, too. I love biking for the distance you can travel, the wind, the strength it builds, but I do have a distinct taste for walking, though I'd have to think about it more to have any ideas as to why.

P.S. a) It's easier to dawdle when you walk, to enjoy the particulars of the places you pass; biking is so fast by default that you have less time to savor details. b) Biking tends to be higher intensity exercise, which may actually take necessary energy away from mind-wandering; in fact, my mind wanders much less while biking than walking, so I'd guess this is the case, but maybe this isn't true for everyone. Moreover, biking forces external attention more regularly as you encounter pedestrians and traffic at a higher rate

I've found this too. I love biking and find it exhilarating, but it doesn't let my mind wander in the same productive way it does on a walk.
