I thought I'd post an update on my Novara Flyby, which as mentioned earlier, is manufactured by Tern and sold by REI.
I bought it slightly over a year ago and took it to my local REI yesterday. The interaction wasn't entirely pleasant, but in the end they generously agreed to a full refund. They have a one-year no questions asked guarantee but I was past that date by two months. (For the record, I would have been OK with store credit, partial refund, or just about anything they might have proposed. I just did not feel safe riding this bike.)
The bike dept guy first tried to tell me that the bike uses Tern parts but the frame is made by REI. I asked for a written documentation. He called Tern and Stile Products (their distributor, I think), and of course, Tern is in fact the manufacturer. I write this in case any Novara owners are reading and are considering returning their bikes to REI.
Recap:
-Tern frames have been snapping in half since several years ago. They issued an initial recall, and now an expanded one.
-Novara bikes are manufactured by Tern. They are not listed in any Tern recalls.
-Tern bikes outside of their recalls have had their frames suffer catastrophic failure, raising, at least for me, significant safety concerns for all Terns and Novaras.
