Ox-Bikes, Traveling Homes and Drifting

I recently received and read the book Monk and Robot, by Becky Chambers, and I fell in love with the world so deeply that I have to admit my crush on it in public. 😊

One of the things mentioned early on is a piece of travel hardware called an ox-bike. Lacking pictures, but going on the way its usage is described, it sounds like a chubby electric bicycle geared for great amounts of torque (as opposed to speed). Torque, interestingly, is great for use when you are hauling a load behind you, and Dex does this throughout the book.

What Dex hauls sounds like they've got a tiny home on a trailer of sorts following them, which sounds so appropriate for me having been recently reading a copy of Gabriella and Andrew Morrison's Tiny House: Designing, Building, and Living.

It gets me thinking:
What would it take for me to build (or have built for me: face it, I don't know how to weld, and would likely need that done) an ox-bike? Or does something like this already exist, with a sturdy enough frame to take some kind of trailer hitch, the weight of a tiny home, and the stress of a chubby enby pedaling with an electric assist of some sort from place to place to place? How do we sort out the gearing ratio for this bike to deliver on torque for rolling a house behind me, and not snatching me backward down an inevitable hill that I'll have to crest along the way? Can we do some kind of regenerative braking to dump power back into the battery pack when I actually need to stop a combined probably half ton of bike, home, and cyclist for a traffic signal, or because we are going down a hill entirely too fast for comfort?

Then, the tiny home itself needs to have considerations made for weight as it would be hauled by me (with whatever electric assist I can shoehorn into the package legally). Everything would be powered by whatever solar energy I accumulate throughout the day, minus whatever is burned by the pedal assist system; will I rest for a day or two anywhere? Pretty sure I will: I am fat, and the bike and house are heavy.

Said tiny home, of course, would have to measure 2.4 meters in one dimension at very least; length would be the most obvious choice. This is so I can sleep inside the thing and have a partition for a toilet. Some kind of paneling that isn't just a plastic tarp would be necessary to me: I don't want walls that suddenly have bear or mountain lion claws going right through them on some peculiar off chance that I end up sleeping in a place where this might happen. That probably means no canvas, but wood, possibly with a thin metal backing to hold up to casual swats and swipes.
Screened windows in the home will be a must: I have to have a reprieve from mosquitoes, gnats, and other bitey bugs.
A grey water and fresh water system of some sort would be vital, and that means water carry weight. That means the bike's PAS and any trailer mounted assist will be desperately loved for getting the machine moving (I feel for Dex's aching legs). However, as a human, I cannot survive without water: I have to drink it, and would like to maintain some semblance of hygiene while biking across a country. I may not always be near somewhere that I could conveniently shower, and that's even if I had a membership to some nationwide 24-hour gym that has showers.

Could I possibly see a country like this?

You know what?
If I can manage to cover 20, 25 miles a day, sure. I would have to plan circuitous routes that avoid major elevation changes and busy highways in favor of regular streets, bicycle roads and paths, and the like.
I would need to figure out currency and medicines: I currently take insulin, but would love to come off that in favor of my old GLP-1, Trulicity -- it did better in controlling my glucose numbers when people learned about the appetite suppression side effect. That med requires refrigeration, which means I have to figure for a way to do that in a tiny home on wheels that is somehow in bicycle motion during the day, stationary at nights. I also have to afford the medicine.
Going on Medicaid in the USA would be a non-option if I wanted to cross-country tiny house cycle: Medicaid is per-state, not nationwide; if you leave your coverage area, difficulties arise in getting treatment and care.
On top of medicines, I have to eat, too! I won't be stationary long enough, likely, to plant and grow a garden. Thusly, I would need to buy food along the way. Maintaining a meat-free diet like I have been for the last couple of years means I'll need lots of vegetables, mushrooms, and fruits to keep the engines going. That's capital I would need to expend at prices that are a big question mark in today's economy.
Having a phone with data would be highly useful for a ride, simply to be able to assure others of my safety, to check my routes, etc.
"Hey, Interwebs, where is the nearest vegetarian-friendly restaurant from here? Do they have a place for me to park my tiny home?"

A challenge, noted, but look:
It is not often that you see or hear about a person, especially a gender-nonconforming one of color, riding any kind of two-wheeled conveyance across any country with a tiny house hooked to their rig. I'd like to be on that list, for the sake of doing something less common.

... But could I maybe have this kind of setup in a non-US country for riding, first? Y'know... safety reasons.

Until next time...
Help us figure out an ox-bike! :)
