Neil Peart, drummer for the Canadian prog rock trio Rush, has traveled most of the world on 2-wheels, and written a few interesting travel books from that perspective. My favorite was "The Masked Rider", about a 6 week bicycle ride around Africa, but they've all been interesting to different degrees.
He had the opposite progression of you, riding from one city to the next by bicycle when the band was touring in the 1980's, before graduating to motorcycles in the 1990's. The one line I remember, and I think it was from The Masked Rider, was something like "bicycle is the perfect speed to tour the world, with anything motorized being too fast to absorb your surroundings, and travel by foot being too slow to get anywhere."
I think his usual routine was to run from his drum kit right to his tour bus, as the rest of the band was waving their goodbyes to the audience, and have his driver get them out of the city and to a scenic route during the night. Then in the morning, hop on the bicycle, and ride the rest of the way to their next destination.
