I agree that cycling doesn't really make you fit as much as it seems (it's an incredibly efficient mean of transportation!). It is well worth it for me though, for that "head clearing". Biking is pretty awesome: you sort of relate much more to your surroundings/city than in a car, you have time to look around and interact, it's great.

I do miss simply walking sometimes too though (it does feel painfully slow when you get used to cycling around!), but if the distances are large (not too large o/c) the bike can be your best transportation friend.
