To proceed further on with the "cycling topic", which of these terms are most commonly found on US roads to designate respectively a path or part of a road in an urban area marked off or separated for the use of bicyclists --- and a path or road in suburban or rural surroundings marked off for the use of bicyclists, but which also can be used occasionally for strolling, jogging, and other outdoorsy activities?
My impression is that "bike route" and "bike lane" are used almost exclusively to refer to a path, street or lane alongside a roadway, whereas the terms "bike track" and "bike trail" sound a lot more appropriate for a peripheral or rural bikeway.
As regards the expressions "bikeway" and "bike path", I think these can be used just about interchangeably for a bicycle path in both urban and rural surroundings.
