Remote-Controlled Treadmill

For sale: Fully functional remote-controlled treadmill. However, I noticed that when the speed is increased to 6 or 7, it malfunctions—I feel it choking and then reverting; otherwise, it operates perfectly with no issues. I’m unsure whether this is due to weight limitations or another problem. For full disclosure, you won’t notice this issue during a test run. Interested buyers, please contact me directly. Sale is permitted.
