The point cyclebuddy made at the start of this diversion is simple: when the market grows in size, larger companies get interested.
You know what large multinationals like Hero and Pon do. They kill small manufacturers and spawn a lot of service outlets to look after their customers. The IBDs will continue to increase in numbers. Those aspiring to be manufacturers will have a very tough time.
Take mountain bikes as an example.
It's accepted they were invented/first designed by, I think. Gary Fisher in the 1980s.
He made them, they did well, other makers had a dabble, more bike retailers took them and so the market grew.
Manufacture is mostly dominated by the big companies, but there are a handful of smaller ones.
Mountain bikes now probably dominate the retail market, what they didn't do was change the way the trade operates as Cyclebuddy is suggesting ebikes will do.
And ebikes are a tiny, tiny market in comparison to mountain bikes.
