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. Now, My Diary I started this diary in 1995 after putting 600 miles on two Nordic Track Forerunners, The Forerunner weighs about 80 pounds and came with off-road tires which were loud on pavement and had high rolling resistance. It cannot really be used off-road, since it has only one wheel driven and there is not enough traction for trail use. Long-legged riders push the seat back and end up sitting behind the rear axle, making the front end much too light.
