If you are biking for an hour...whatever. I used to go to cyclocross practice and have coffee after/eat when I got home. Yesterday I did a 2 hour detour on my commute and ate when I got to work (and other days I eat cereal before doing the normal 6mile commute).
If you are doing a century...then you gotta eat (well you gotta eat during the ride too...) but otherwise before or after shouldn't matter as long as you are hydrated.
