Tern issued a recall in the USA last year after two frame failures. There are at least 6 frame failures in the UK since Dec 2013 with no formal response from Tern. This topic has been discussed extensively on Tern's site ( Tern Link D8 frame shearing in two | Tern Folding Bike and Folding Bicycle Accessories | United States ), however the discussion must move here for a few reasons:
1. In early April Tern made the forum private ( you must register ), and registration is very difficult....it took me 15 min.
2. They have disabled email other member option.
3. Their site was down last night for an extended period.
4. The pulled the USA recall notice from their site, and will probably pull the forum soon. I imagine it will be spun as a site redevelopment project.
Please share ideas and solutions for people affected.
I have contacted the CPSC, and bicycle retailer. I expect a story on this matter to be published shortly.
