Hi, André is right but I think that part of the problem comes from the fact that the available documentation is sometimes contradictory. A good starting point for anyone wanting to learn more is the Belgian conventions page (http://wiki.openstreetmap.org/wiki/WikiProject_Belgium/Conventions/Cycleways).
Indeed, oneway:bicycle=no is the recommended tag if cyclists can use the way in both directions. This works best with most apps. Using additional tags to describe more precisely the kind of infrastructure the users will enjoy is nevertheless helpful, for routing apps, for statistics about rate of protection, etc. Despite Belgian traffic rules use the same word (fietspad - piste cyclable) for a reserved track (with D7 or D9 signs) and for markings (two stripped lines), in OSM-taal those could be tagged with cycleway=opposite_track and cycleway=opposite_lane respectively. In Brussels, it is fairly common to paint logos or inverted V-signs on the street but those have no legally binding value and would probably not count as anything with "cycleway" in it. I know that the wiki is not always the Bible but I saw that someone has recently rewritten the page about cycleway=opposite (http://wiki.openstreetmap.org/wiki/Tag:cycleway%3Dopposite), to recommend *against* oneway:bicycle=no. Shouldn’t we try to find a way to clarify this, so that we could tell new users how to map properly? Cheers.
