Pro Form 520x

I have a pro form 520x. It’s old, but I really like it. It’s starting to have issues. When I go to walk/run on the running belt stops iris real jerky. So can I replace the belt or would that be the motor?

Thank you


  • it's most likely the walking belt. (its a friction issue) if you can get me the model number of the 520x I'll get you a link for the belt. Here is a code you can use on the checkout page for a 5% discount (5offkevin)
