For those seeking exotic groupsets, bear in mind that patents can be (are) geography dependent. This came up on a recent Nero Show with Joe from Panda Podium, or something like that, can't remember.
So, when there are questions around 1. why is this groupset not available outside China 2. is it true it might not work / risks getting bricked outside of China, it might simply be a legal protection.
Point being, don't assume it's a conspiracy theory so the white man pays more, and that you'd be scoring a great deal going exotic.
Having installed lots of twoo electronic groups, starting with the first gen, my only recommendation is: dont. do not be an early adopter, not now that you can get mini groups from shimano di2 on aliexpress at very decent prices. Out of all the bikes i've built, virtually all the issues that arise are groupset related, and almost all of these are electronic ltwoo related. When the stuff works, it works. But much more often than you'd like, it doesnt. And that's extremely annoying. All the more now that (i'm in Europe) tariffs, shipping, and general shenanigans on Aliexpress have increased prices 40% in a few months. It used to be that you could replace a shifter or derailleur or battery housing for cheap. Not anymore. Do look at replacement parts, 1 shifter can now cost half of what i paid for the entire ltwoo group. And you're hostage of that, if the rear derailleur or a shifter needs replacing, you either replace it, or scrap the entire group, there's no in between when it's electronic.
