I recently stopped into a Yamaha/Honda dealership not close to where i live, and there was a lineup of entry tier E-bikes. Present on the floor where not insignificant amount of CFmoto "pitbikes" or something resembling a PW50/ttr50 but electric. The price was fair for those, but wait for clincher...
Here in Australia we have the ADR, it is an engineering process that destroys at least 1 or 2 units for "testing" the prove that given unit and it's designs are all meeting or exceeding current safety, consistency and regulatory requirements (always esoteric or at least endemic) for Australia. To see an ADR approved (oh yeah, its like DOT i suppose?) electric dirtbike/motard was actually not offensive to me, i also (and this is from a 59 club rocker) do not hate scooters as a transport concept.
At length i spoke with the salesman (a bloke in his 50's at a guess) about battery technology, regenerative braking, and the local deviants, delinquent teens, and ne'er do well riders of the surons, stark vargs and bafang hacked MTB's. It's definitely a thing, and the bigger changes towards safer battery tech (LiFePo v LiPo) and better ReGen use make the E-bikes way more appealing, yet something about having to wheel the beast back to a charger everytime it needed topping up seemed a negative.
Both the Salesman and I agreed independently that Hybrid Bike technology has taken too long to implement, and how wonderful the concept of a hybrid "road dog" or "ultra-classic-extra-glide-terraplane" is possibly. Realistic expectations of the vision of a two wheeled dreadnought could easily be substituted for a version of a large displacement Japanese or American super tourer (like the Goldwing, Cheifetan, Ultra-glide) with aforementioned Hybrid system.
Edison Hybrid trucks from Canada, build (or are developing) retrofit systems for existing truck chassis using big high output generator plants, with batteries and electric drive motors, capable of good kinetic energy re-generation. The fuel saving completely depends on the type of driving/riding you do, so each use case has it's merits. I think for heavy hauling highway use, its as good as 5 to 10 percent, inner city, or stop start work, they quotes 70 to

%... Still, thats better than the figures, stats and results of current billionaire run E-cars and E-trucks.
After that part of the conversation we drifted into turbine powered things as it seemed we spent too long talking about green

.
Things are changing in this space, and until we get to a better battery technology, more skill at ReGen brake use, and better charge technology it can only get better.
But having a fuel cell at home that uses excess renewables generated power to make Syngas, and lubricants is more what i am saving my money for, because nothing saves more carbon from spewing into the atmosphere, than recycling and old beater with some class and patina. Building a new thing that is not recycled easily and replaced every EOL isn't the solution for waste, emissions or resource scarcity, why people get sucked in, is the same reason billionaire class rules the world now.
Welcome to the Kleptocracy.
I lost the plot here, but thought this was the best place for this rant.
