  Well, those look like kilodollar+ custom jobs. I guess I was thinking more stereotypical department store bike from China, where the mechanics aren't generally much of a priority so introducing something isn't very dangerous. You can either shove innovation in at the top where R+D fits in the budget, or at the bottom where reliability is never assumed anyway.
