You should be aware that any negative comments here about Nordic Track and the Fourrunner are historic now, and pertain to the company under the old ownership, not the current company.
ICON has a Web page up explaining what has happened , including their policy on warranties.
I have revised this page to remove general Nordic Track comments, in fairness to the new owners. But the record of the product itself remains unchanged, and this page is about the bike, not the company. I had a forerunner, stripped the gears, broke the frame, same response from Nordic Track as you received. I am still so angry with them that I find it difficult to mention their name. I finally gave up and tossed the whole thing.
