May not be mountains, but you're riding mountain bikes on steep bush tracks.
Obviously you guys haven't tried to ride anything like a decent mountain bike down some of the more extreme downhill single track trails (as opposed to 'bush tracks') in the dedicated mtb parks near Kalamunda, Dwellingup or Nannup (where they have the only double black run in WA) and unlikely you'd be saying "may not be mountains" after sending it down one of those trails!!! Fyi WA has some of the best most varied and well built mtb trails in the country and there's plenty of different trails to keep one entertained when there's bugger all wind! Also imo kayaking another good low wind alternative
