Used treadmill, displays heart rate on the screen, comes with 12 programs, works well at speeds of 2-4 km/h, but at 8 km/h, after half an hour, there is a smell coming from the motor. This could be due to infrequent use or possibly the electrical supply in my home is weak; I’m not sure what the problem is. It comes with a front vibrating device for the waist and abdomen, in good working condition. Also includes two small dumbbells. Selling to the highest bidder.
