Like, the whole point of these things, at lesst as I see them, is that you get that free lunch on the way down a hill, then when going up a hill, well yeah, you still aren’t gonna like, be 1:1 be able to power right back up it, but it will be easier going up that hill than if you did not have your free energy lunch on the way down.
This then results in you not needing to expend as many literal calories going up a hill, so now, you don’t need as much food to recharge after a ride, thus you do actually on net come away with at least a portion of a ‘free lunch’, in that you don’t need as much food.
But yes, I will give you that… the overall weight added to the bike from the batteries would have to be in a manageable range, so that the uphill assistance is not just entirely used on uh, pulling its own weight.
The problem with “go down a hill” is that the LinkedIn idiot wants to use the power of one motor to generate power in the other. Regenerative braking only needs one motor and it acts as a generator when braking.
I mean… you can do regenerative breaking in a hyrbid car, where the main LiON battery is also charged from the ICE engine.
I had a hybrid Prius C that worked this way.
Roll it down a hill, far enough, in the right mode?
Recharges the main hybrid battery.
And then, you can also put it into a low power, EV only drive mode. Can’t do inclines or go fast, but you can get up to about 20mph on flat terrain.
Like, I’ve done that at least once, as a kind of makeshift jumpstart sort of thing.
Presumably, it may be possible to scale such a system down to a bicycle, or maybe moped or motorcycle.
And the LinkedIn guy specifies that there are two different batteries, which are capable of transfering power between each other.
So their system is regen braking -> bat 2 -> transfer -> bat 1 -> drive motor.
Personally, I don’t even see why you need two distinct batteries, just have a powerstation type thing with a some software that regulates power uptake and output intelligently.
What he’s said can be interpreted that way, if you add some words he didn’t say into this post…
… but he didn’t actually say that.
A ‘continuous self charging loop’ is not the same thing as… that, but which also generates infinite energy or is somehow overunity, over 100% efficient.
That just means there is a continuous loop by which energy can flow from the regen braking to the motor.
It doesn’t mean that energy is always flowing through that loop… it just means that some amount of energy could be.
It doesn’t mean that power coming into the motor or batteries always exceeds the maximum power consumed by the motor.
(that would infact be very bad and cause the batteries to explode/burst into flame at some point if we’re talking about LiON)
Continuous loop is… an actual electrical engineering term, and its actual meaning is basically as I have just described.
Now sure, if this actual LinkedIn post is rather recent, well its rather cute that he seems to think he is the first person to come up with this idea…
But, it is also cute that the vast majority of commenters in this thread are suggestible (by way of being mentally framed with a narrative by the comm this is posted in and the post title) and have either poor reading comprehension, or just didn’t bother to actually read what this ‘lunatic’ wrote… and are acting like they’re better engineers than this guy, that he’s bonkers… when in actuality, they’re all showing their own asses unintentionally, proving that they don’t know basic electrical engineering terms.
For this guy to have actually been trying to describe a perpetual energy devicre, he would have had to say something like ‘a continuous- ly self charging loop that is over 100% efficient’.
He even specifically said his goal was to reduce the need for external charging.
Not eliminate, which would imply he thought it was overunity, but no, just reduce, which… would indeed be the result if his system worked and granted an extra 10% or 20% to overall EV bicycle range.
Yeah, in engineering, as well as language, precision and small details can make for large differences in the end result.
You do get about 5-10% more range with regen on an ebike, the downside is it needs to be a hub motor which sucks at climbing hills, and one with no internal clutch which means pedaling with the motor off wastes a ton of energy.
Counterpoint:
Hills exist, go down them.

Regenerative braking is not the problem. Thats been solved. The LinkedIn user is trying to invent perpetual motion
They’re not actually describing that, explicitly.
