Hub generators are where it's at. Look at this which is dirt cheap

make it cheap.

That's got a catchy name - "Generator" - but AFAICT that's just a hub,
not a dynamo. It doesn't generate any electricity.
I thought that might be the invention of the seller, but was
apparently contrived by the manufacturer:

The eBay $10 price, plus $8.25 shipping, is the starting price for an
auction and not the "buy it now" price. Retail price is about $42:

That is really odd - why would you call it a generator hub if there was no generator in it? There are plenty of generator hubs on the market such as Shimano Alfine S501 which is 3 watts at 6 volts. This would easily drive REALLY bright LED head and taillights.
You ask why?
[raises hand] Marketing!
c.f. Communist front named 'BLM', another successful example
of 3 card monte.
Now we get some propaganda from SRS and Kragowski
