High end bicycles are usually made in Europe or Japan. Like guitars as an example Chinese made are the worst even the same brand and model Korean maybe Japanese are the best quality while not being too expensive. Mexican is decent but not as high quality as Korean. American made is over priced but there for more expensive models.
It's rare for China to have good quality. Their focus is on quantity and cheap but that may be what you want sometimes and occasionally it lasts.
Practically nothing is made in USA because we have the world's most valuable currency. Without tariffs we can't compete. A Mexican making $8 an hour enjoys the same lifestyle as an American making $25 an hour. The corporations are too greedy to allow tariffs and they donate big money to politicians.
I ride a ton of chinese carbon fiber race frames and wheelsets. I trust my life with them, you would be surprised how good they are at some things. Currently waiting on a custom painted gravel frame from one chinese company and a custom built to order wheelset from another. Both are considered high quality.
My main ride though is a Trek Madone slr9 gen 7 project one made in the USA but I still love the chinese frame to beat on when needed.
