Just like you won't find enterprise software in a big box store, nor its price online, you won't find a price for a wheelchair that is fit for daily, long term use online. In any country.
I don't know about the prices in Germany, but in the UK, a decade ago, the retail for such a wheelchair is about 5,000 GBP. Adjusting for inflation is left as an exercise for the reader.

Hospital chairs and everyday chairs are both technically wheelchairs, but they are totally different products for different purposes.
I don't think these wheel chairs have any magical properties over the stuff used in Germany. Other than that they are really expensive.

If you need a wheelchair for a couple weeks it's fine. If you need it for life, not so fine. People who can't afford a proper day chair or are mired in insurance hell sometimes make do with them, but they can suck ass. They're totally different products and are suitable for different uses.
They're different chairs; $200 hospital chairs on Amazon have no relationship to the price of the sort of chair the company from the article is working on.

Not-A-Wheelchair is offering wheelchairs customized to your dimensions. Many insurance wheelchairs that cost $$$$$ are also custom built/fitted to your dimensions. There are absolutely cheap wheelchairs in the US. But people in wheelchairs due to permanent disabilities want comfort and rightfully deserve it. The designs being worked on here by Not-A-Wheelchair are basically all "lifestyle" chairs, rather than boring "temporary injury" chairs.

There are lots of models with very reasonable prices and features; mostly well below 1000 euros. Including a few electric ones. Manual ones seem to be generally well below 500 euros. At 1000 euros we're talking some seriously tricked out models with all sorts of features that I'd probably want if I was in the market. I'd probably spend a bit more. And I'd be very surprised to not get support from my insurer for this.
The model in the article pretty bare bones in comparison. Not just a little bit. Like really bare bones. I'm sure it's great and ergonomic and really good quality. But what's the real story here? Inept US manufacturing or corrupt US insurers? Or both?
For reference, I just found a very reasonable looking electric wheelchair for 999 euros by a company called WISGING. With some 5 star reviews from buyers. In stock. Would arrive around 9 October if I ordered it now. 20km range, apparently.
The stuff on Amazon looks like it comes mostly from China where they are probably producing these things in large volumes to provide affordable, decent wheel chairs for whomever needs them around the world.
The world is bigger than the US and people use wheel chairs all over the place. The kind of pricing and quality cited in the article in the US would be completely unacceptable in most parts of the world. And never mind the shipping times. Is it not possible to simply import these things? I'm sure there are some tariffs to deal with but even so, what's stopping people here?
