I'm just getting back into bicycles after a long medical layoff. The hard part is not the peddling, it's butt & hand break-in.
That said, while the bike in the drawings isn't optimized for off road, ( clearance ) the modular design offers wonderful cheating possibilities.
More power, different programming on the throttle control, etc. And a fuel cell variant?
One problem with fuel cells is you either use hard to store hydrogen, or complex chemical plant gear to turn, say, propane into hydrogen built into the vehicle.
Cryogenic hydrogen storage in vehicles has long been best left to... Astronaut types. Brave, highly educated, engineering oriented, and willing intelligent risk takers. Test Pi!ots. ( because of the explosion )
And the chemical plant auxiliary needs make fuel cells that run on hydrocarbon fuels, expensive and too massive for, say, a bicycle.
But if that chemical plant refueling module can sit next to your house and he plumbed into your natural gas line? And you just swap out modules from your bike? That's a different paradigm.
( And my seeming obsession here is because the Lithium for current tech batteries comes from countries that either are threatening war, at war, with us, or threatened by a probable war. So non-strategic materials may be really important. The less said about Rare Earth elements... )
I have e-bike. I am in process of installing Kindernay hub transmission on it because of it is maintenance free an I hate to maintain regular bicycle transmission and keep spending money on new sprockets and chains.
I've trashed regular derailleur and internal hub transmissions, and the difference to me is "can I fix it an hour's walk from civilization with a leatherman tool and a stick?"... At least enough to pedal home in a low gear.
Plus the cost. Not that a Shimano Deore gruppo is cheap.
I suggest you contemplate exactly how it works, and consider how to jam it so it can keep sending power to the wheel. But in any case, enjoy.
Hub transmissions can be mechanical porn.
( A project log of the crew that built from scratch 2 Albatros fighters, is serious woodworking porn. After The Berlin Wall was torn down, in a corner of a factory in E. Germany, 2 Original engines, brand new in crate, were found & donated to a museum. So the museum made a deal. If a team of enthusiasts built 2 planes, they could briefly fly them, then return the engines, and the brand new reproduction airframes, to the museum. The Ultimate NOS story. There are AFAIK no original Albatros flying.
When Erik flew to the Milwaukee tundra that winter . . . He took the lowest job offer he had, from H-D, to get into motorcycles. If I recall one offer was from Lockheed or some aviation firm.
Could be wrong . . . But, I’m sure it’d been a dandy.
I saw my first TV ad for the Lucid Air this morning. Like Tesla and Fuell, they are using the direct sale approach. This whole electric vehicle thing might be catching on. https://www.lucidmotors.com/air/configure
The $70 & 90K versions look cool, but without a Lotto win...
Erik was probably better off at HD than Lockheed, Aerospace is really dependent on Government military contracts. Which means every Election, they might cancel your job. And the multi-billion dollar project that is ready to fly.
The 2 examples that frost my cupcake, are the Boeing SST, which cost more to cancel than to build and start test flights. And the Vought F5U flying pancake STOL Naval Fighter that was cancelled because the Future had Jet Engines.
I suspect Erik's contribution to WW1 would have looked like a cross between a Fokker V.20 and a Spad. But faster. And they'd still be arguing about it.
To bad Lucid is so in love with the California/Hollywood narcissistic mindset, but of course California is going to save us from ourselves. What would we do without them?
Remember the previous rich guy electric status car? I especially loved the leaf preserved in plastic, in the Virtue Signal model. It really was a nice car. I couldn't afford a tire on one, but that's true for Bugattis too.
