From David Byrne’s review in the New York Times of Jeff Mapes book, Pedaling Revolution:
[Mapes] argues that cycling promotion can raise society’s level of general fitness, since people exercise more when it seems less like exercise and more like something mostly enjoyable that also performs a function, like getting to work. “Bike and walking advocates,” he writes, “have been rebranding their cause as ‘active transportation,’ which manages to come off as nonthreatening to your average couch-bound American while carrying a nice touch of gravitas as well.”
Yes I would describe my bike commuting as “something mostly enjoyable that also performs a function.” I wouldn’t count myself as a “bike and walking advocate,” per se; I’m happy to let other people do their own things.
But I like it, and if your circumstances permit, you should discover whether you like it, too.
