I used to work for a while at Canadian Tire and used to assemble and repair same "bikes" too. They are made of plasticine metal and are very crudely made (Welds, thread quality, assembly, brakes quality etc.). I would have banned them from sale at all. Because they are simply dangerous. But this is just my impression as a bicycle mechanic.

Hyper used to have pretty good customer service. I would say the tariffs are making it not cost effective for them to keep replacement parts in stock, you will probably see them disappear along with a bunch of other bike manufacturers.

The frame, motor and battery on this bike seem decent enough, everything else not so much.
By plasticine metal do you mean cast metal? Can't find a suitable definition for it's use in this context.
I think he means the typical BSO**** that is made with a flexible soft wobbly frame or of some unknown alloy or combination thereof that doesn't seem to be suitable for much of anything useful.
The frame I took apart to use pieces of for Delta Tripper was so flexible I could bend it with my hands. I ended up only able to use the seattube with BB and OPC set, and even that flexed and twisted while pedaling. I tried to use the downtube or toptube (don't remember which) as a steerer extension, but it twisted so much it would've caused steering problems.

I don't know about the overall quality of the frame metal, but I it is thick aluminum welded together with fat welds.

So used it a fair bit last weekend, worked great. I could wish for 350W, rather than 250W, for the steeper/longer hills. And perhaps some day changing over to a wider gear set or wider IGH gear set to give higher possible speed, although I think I need to tweak the derailleur, I don't think I'm getting into the lowest gear, so that might be part of my impression.
All in all, well over 10 miles, and it seemed to use not a whole lot of power actually.
More importantly... what do ya'll think of Shimano M375 calipers? I definitely need to replace the front ones, and they make quite a bit of noise when in use as well. Although I can live with that.

Yes to the Shimano M375 calipers. Best improvement you can do to the bike. Do both brakes.
Yeah, the derailleur has a hard time climbing up to the biggest cog. A long cage derailleur like this: Amazon.com : Bike Rear Derailleur RD-M3020-SGS 8 Speed Direct Mount for Mountain Bike, Black : Sports & Outdoors would solve that.
I'm probably going to try out a Driftmaniac 11-34 freewheel too.

Needed to remove the rear wheel of my Hyper bike in order to tighten a fender screw that worked loose, so I also replaced the freewheel and derailleur.
The new DNP freewheel is an 11 to 34 tooth, it replaced the installed 14 to 34 freewheel, so a bit more top speed.
Replaced the Shimano Tourney derailleur with a longer caged Acera .
Also did a little wheel truing. This is it for improvements on this bike. New seat, brake calipers, freewheel and derailleur. Total cost, including shipping and taxes, is about $500.
(Edit: the drive chain failed a couple day ago after maybe a hundred+ miles. So, unsurprisingly, the installed chain is junk. So replaced that too. Bike is now a $520 mid-drive.)
