Exercise Bike Repair - Drive Belt Slipping on Life Fitness C3 Cycle Exercise Bike

jojojohny

Hi, I wondered if anyone could give me some pointers for either tightening or replacing the drive belt on my exercise bike which keeps slipping (making it unusable). I bought it in 2016, so its not exactly that old, but it is outside of the 3 year warranty. I've tried looking through the manual and the manufacturer's website and cannot find any information on how to perform what should be a straightforward task I would have thought. It seems I'm supposed to pay for a professional to come out and replace the belt, but I cannot afford to do that right now unfortunately and also it does seem like a fairly simple task that I cannot see why I cant just replace it myself (apart from the fact I don't know how!).

I have removed the cover and can see the belt. It seems like there are some little fragments/shavings of rubber on the ground below the belt which I guess have worn off over time, which makes me think I should probably replace it. Does anyone have any experience of doing this themselves on a similar bike? I would really very much appreciate any suggestions or help anyone can provide, it would really help me out. Thanks a lot!
