To me commuting is a generic term that means going to and from work, independent of mode of travel.

Of course this forum is about a specific kind of commuting, commuting by bike, bike commuting, riding your bike to work as a form of commuting, or whatever you want to all it. For some of us this may be a mixed mode commuting involving bikes and transit.

Maybe what we need is a special word for bike commuting, like "cyclomuting" and we can be "cyclomuters"
