Miles with Maggie (1986-1988)
After two years and 10,000 miles on the Winnebiko, I was ready for a few changes. My computational tools had begun to feel primitive, I missed the rich community and toolset of ham radio, I couldn’t write (or do much of anything) while riding, there was no on-board development system, and I had grown weary of traveling alone. After wrapping up the Computing Across America book project and finding myself pinned down for a few months in a brief flirtation with employment, I threw myself into development of the Winnebiko II.
I had already spent months dreaming about what it would take to have a rich set of of capabilities available while pedaling, so the project moved with a swiftness that I remember wistfully. Between my innate geekery and creeping featuritis, this new machine turned into an elaborate contraption… including a binary chord handlebar keyboard that would let me type in ASCII while pedaling.
It was total immersion, that summer of 1986, though of course I already had camping gear, business protocols, and the bike itself more or less fine-tuned. But the geeky parts were intense, and this photo essay of console fabrication gives a sense of the scope… intense learning curves intertwined with development of the bicycle control system, integrated systems including a hacked Model 100, the handlebar keyboard and other services run by an embedded 68HC11 microprocessor, packet data communications, remote-control features, a robust power system with 20 watts of solar panels, and lots of upgrades to the bike itself. I met a woman named Maggie who was willing to abandon her midwest lifestyle and hit the road, and there was a buzz of excitement in the air.
In August 1986 we drove a van from Ohio to Vancouver BC, putting the yet-unfinished Winnebiko II on display at the Expo 86 world’s fair. After an amazing week of hanging out with human-power and kinetic-sculpture wizards, we found a place on Bainbridge Island (near Seattle) to finish up the major systems… then continued down the West Coast to begin what would turn out to be a 6,000-mile adventure.
The console system shown in the photos let me type in binary at about 35 words per minute while riding, had a packet-radio mailbox for email and chatting with fellow hams, and was equipped with a speech synthesizer to let me remotely chat with people standing around the bike… or startle them with automated responses to security system alerts. I carried an HP Portable PLUS laptop in the pack, but while underway I used my old Model 100, repackaged into the console and augmented with a variety of hacks. Decades later, the machine caught the sun one afternoon in my lab, bringing back fond memories of the road:
A delightful CNN piece from July 1988 gives an excellent 3-minute overview of all this paleo-geekery in use… mentioning “1.7 megabytes of memory and a battery-powered 3½-inch disk drive”:
Throughout this phase of the adventure, I was publishing on GEnie… with an ongoing online column called “Computing Across America” that had about 50 chapters by the time it was over. Maggie and I made our way down the Pacific Coast, landing in Silicon Valley in February 1987. We stayed for a few months of system-building and enjoying interesting people, then drove east in the old van to take care of a few details at the Ohio base-office and then continue the bicycle trip… northeast through Ohio, Pennsylvania, and New York… then down the East Coast to Florida. Here the adventure paused as the book was finally released, with hundreds of pre-ordered copies to sign and ship. We converted an old school bus into a mothership that carried us 16,000 miles over the next year, rumbling around the US to visit trade shows, conferences, hamfests, companies, universities, and friends… converting book sales into gasoline purchases and generally enjoying life. All this was fun, but I was already planning the third version of the bike, keeping my eye open for potential lab space.
By early 1989, we were back in Silicon Valley, working in the first of many bikelabs to conjure the beast that would roll out three years later as BEHEMOTH. This would be over-the-top in a weirdly satisfying way, but the Winnebiko II shown here was by far my favorite of the three versions. It hit the sweet spot of usability, geekery, practicality, and what my old friend David Berkstresser called weirdness quotient — the bike was packed with technology and delighted the media, yet was light enough to be practical and fun. Although architecturally inflexible, it performed its job beautifully.

My old documentation binder contained this 1987 document describing console operation, and it reveals the gritty level of the interface compared to the sleek systems we now take for granted. I smile when I see old video interviews in which my fingers play over the switches to boot the control system or send Touch-Tone sequences via ham radio to make the bike talk. If you’d like to learn more, here is a discussion about the anatomy of the Winnebiko II that describes the system in more detail.
There was a lot of publishing during this phase of the adventure, and here are a few relevant entry points into the archives (each piece has previous/next links at the end, as well as a trio of posts that the system thinks are related… and they usually are):
- Media coverage from the Winnebiko II era
- Series in Computer Currents about emerging technologies that made the trip possible
- Series in 73 Magazine about communications-related systems
- Poster of the Winnebiko II in our online store
