By Steven K. Roberts, famous for being one of the first high-profile "technomads". I remember reading his "Computing Across America" series on GEnie, back in the day. He had a high-tech bicycle and wrote email using a chording handlebar keyboard with 8 keys (4 on a side) that he used to input raw ASCII into his computer.
Roberts started with a recumbent bicycle with a little onboard computer and control panel he called Winnebiko. Then he switched to a thing with a trailer and solar panels called BEHEMOTH, "Big Electronic Human-Energized Machine ...Only Too Heavy" a 580 lb monstrosity that he could sometimes pedal at 3 mph, but he still put 17k miles on it. Later he got set up on a sailboat he called Microship, graduated to the Nomadness, then the non-sailboat Datawake.
