[...] I find the sentence "He'll usually go to work by bicycle" to be very awkward if it is to mean that he presently has that habit. Having thought some more about it, I have realized that it is not because of "will" but because of the adverb "usually." If that sentence (with "will") is to refer to a present habit, it would be far better, in my view, to use "often" instead of "usually."
I fully agree, David. You are definitely right that "often" sounds much better to express a persistent present habit.
