If you work or have access to bike shop buying you will quickly see how many "unknown" brands of bicycle are available. China probably has the most. One brand translates to "Happy peeping canaries" which I used back in the day for a Velo News TDF team in the Tour...we were not happy at the end...
The brands you list are what is typically built/sold as name brands here. They are also much more expensive than the cheap...cost wise...bikes built and sold in the countries you name. Those countries use bikes as regular, daily transportation for the masses that can not and will never be able to buy a car. They do not and will never earn enough money, in general, to buy a car of some sort and this is the best they can do...
