Good evening! I bought a cross trainer for myself three weeks ago, and now I suddenly can't feel the resistance anymore. I have the Sportsline cross trainer x11.9. I opened it up, but I don't know anything about it. Yesterday it was still working, and I could feel the resistance increasing in my thighs, but…
Good bye, Recently, my mother's Kettler CX2 exercise bike has been missing resistance. We've already opened it up, but haven't found any problems. Does anyone know the cause of the problem? Thank you in advance
Good bye, After my brother, who's 15 years old, repeatedly hit my father's Kettler CX2 exercise bike, it started making a grinding noise when I pedaled, as if two components were rubbing against each other. Does anyone know what the problem could be? Thanks in advance
