I wish I knew what company originated the stuff you're looking for.
However, the L-faster "brand" covers a whole lot of stuff, some of it not even ebike-. ev-, or even bicycle-related, so you would have to specify exactly which system or specific parts you're looking for for me to be able to help poke around for another seller of it, or at least something similar.

I've not used Google for over 10 years.. won't go near it generally, but I just tried your link and it gives me a reCAPTCHA.
I don't get any of those, but I'm using Ublock Origin, Noscript, etc. on an older Firefox version, and only allow the things I wish to. If pages require something like that to access them, then generally I simply don't go there. Most of the time I can simply block the stuff I don't want to deal with and hte rest of the page is accessible (like google's search page).
So I searched "l-faster" on startpage.com (who supplies google results) and got "Sorry, there are no results for this search."
I think there may have been something wrong at the time you searched, or perhaps there is something in your browser that's misbehaving, because when I go to
https://www.startpage.com/do/search
and use
"l-faster"
with or without the quotes, I get essentially the same result set that google provides. A partial quote of the text portion of the first page is below:

The L-faster specs also do not match the specs of any other motor I've looked at (posted
here).
Keep in mind that "specs" are typically up to the seller to "invent", in this particular line of business. It's not right, but it is extremely common. The only specs for things like this that you can really trust are the ones you have personally determined in real-world testing.
Even USA sellers are guilty of this--just look at Lunacycle; they have a history of this recorded here on this forum, although they may have erased it wherever they have control over it. Other such sellers do the same kind of thing, but people still buy from them, so they don't change.
One example is that there are plenty of "500w" motors out there with much higher labels on them by some sellers; sometimes also sold as kits with controllers or batteries that couldn't possibly create the kind of power described.
Another is batteries that couldn't output the current specified without such severe sag that any bms they might have would shut off (so some don't come with one for that reason), or they'd actually heat up enough to catch fire if you did pull that much current for any significant amount of time. Or they specify absurd capacity ratings (this used to be mostly a problem with *fire cell vendors, but now it happens with complete batteries from more and more sellers more and more frequently).

It's unlikely that a seller will keep the same model name & then replace the OEM, which requires maintaining the same specs.
We *expect* that...but it isn't the case with this kind of stuff. Various sellers frequently advertise a specific set of items, even something that is given a name and model number in their "catalog", but then ship you something different, because they can't get that stuff anymore, so they got something different and sold it as the same thing...whether or not it has anything to do with the specifications they originally advertised. They don't generally change the ad regardless of complaints or problems caused by this practice.
It's unethical...but they don't care. It makes them the same money either way.
If the webshop is in English, they quote in USD, and they accept USD, and most importantly they ship to the US, then they're doing business in the US where US laws and customs are in play.
If you can get a lawsuit or other legal action pushed thru into China or wherever those sellers are actually located, when you run into problems with such sellers, I'd love to see the results be positive...but i don't expect that they would be.
About the only consequences most of the people posting here on ES have managed to get imposed on such sellers when problems arose was to sometimes be able to get their credit card company do a chargeback, or sometimes be able to get paypal (etc) to refund the buyer. Even those don't always work, depending on the specifics of the situation (for instance, sometimes they're required to ship the item(s) back to the sellers on the buyer's dime, and get confirmation from the seller that they were received, etc., and that isn't always possible, for various reasons, or practical from a cost standpoint, as the return shipping may cost more than the item(s)).
Hell, sellers frequently don't even ship items legally. Batteries and other hazmat stuff doesnt usually get shipped that way, it is often just called "toys", and as one of the consequences, may never make it to the buyer due to random customs checks.
It might be nice if the business rules and laws were all strictly enforced, but they're not, and I can't imagine they ever will be. There's just too much stuff being sold and shipped around for there to ever be enough people to keep track of it, and you can bet anything you like that buyers aren't going to tattle on the sellers, most of the time, because it benefits them greatly not to do so, with lower prices, etc.
Sure, there are ethical sellers. But they're not the majority, and they can be hard to find.

And because most people dont' actually care about anything other than getting a good deal (at least what looks like one on the surface), that's unlikely to change anytime soon.
I do understand you'd like to change that. So would I. I've tried in the ways I can...but too few people care to make much of a dent in it.
