To unbiased, knowledgeable people on this subject....Are the newer Tern bikes (Node D8, etc.) safe to buy? I assume all bike shops removed the defective, recalled Tern bikes and Tern has found and fixed the problem(s). I hope this is the case. Seems like only only affordable big name bike brands are Tern and Dahon but hearing all these prob;ems makes me hesitant on buying either one of them.
