Half the bikes on a sample of 130 units is not simply anecdotal.
I dunno, it's one experience documented by one person (who to me is an internet stranger) from a specific point in time at a specific place with a number of units that is a small sample compared to the overall production figures. I'm not really sure what conclusion I can draw other than I'd need to do some more research if I really want to know what is going on, if anything. Which I tried on Google but couldn't really find anything. That might be because despite the internet being universally populated by well educated complainers that Tern GSD owners just happen to be the sort of person who cannot internet (really?!), or don't actually care, my Google fu is weak, or it might mean something else. So I can ask around if you like?
You do you, boo. Just make sure you ask whichever shop you buy from if they addressed the issues mentioned before you take it home. If they give you a confused look or try to tell you it's normal for the brakes to rub on a new bike, go to another shop.
