It's cool to see someone make a video of going to the Taiwan bike show and talking to some people in the industry.
I guess a Taiwanese frame is much more expensive than a Chinese frame as well. It really doesn't surprise me that the big brands have someone there full time checking and maintaining QC in the factory.
On the other hand, I think if a couple of guys really wanted to start a new bike brand, and had about 250,000 USD to invest in it, it can still be done.
