That would seem to me to be the larger issue — at least here in the U.S. among the ranks of the Gentlemen Velocipedists. The big bike brands are, understandably, pushing their new model bikes with new features. (I remember when it was the newfangled elliptical front sprockets.)
I do feel the article is a little over-worrisome though. Any bicycle that replaces an automobile has such an overwhelming positive impact in so many areas that complaining about the energy required to make an aluminum frame vs. a steel one seems to be quibbling.
My understanding too is that energy intensive manufacturing, like that of aluminum, often take place in regions of the world where energy is cheap: as an example the hydroelectric power along the Columbia River in the U.S. North West.
