IMHO, it all depends on how hard the rides you do are. Some folks can ride 7 days a week and there are those that ride a "hard", "harder", "hardest" on consecutive days then need to take an active recovery day where active recovery is ridding stupid slow, just on the verge of falling over.
When I say hard, harder, hardest I mean that you are really taxing your systems on the 3rd day to the point of exhaustion e.g. VO2Max sessions, Hill repeats
