the Nooyah brand has some good options. I went to China last year and brought a bike back to Brazil inside a Nooyah BK008 model
very good quality, especially for the price (I paid a bit over USD100), the fabric is thick so my impression is that it was going to be durable, and it came with wheel bags, a kind of 'block' to protect the bottombracket and chainring.. very protected
I ended up selling it right after being back (and made some profit hehe), I really only bought it for the travel back, since the trip was long and with a number of layovers, without the bike bag with wheels and all, I wouldn't be able to make it lol
I think I've found out that Nooyah makes the same bags as Canyon and Scicon (maybe the OEM?!)—for me, at least, that's currently the most exciting china option
