A Sole treadmill base can be made a S ton lighter by removing the motor temporarily. You can also move it up stairs by taping or strapping it to a big sheet of thick cardboard and using the cardboard as a sort of sled. I moved my treadmill upstairs, by myself, using this method (although that was 10 years ago when I was only in my early 50s).
Hi, I got Sole S77 in Canada and want to add it in the second floor but my friends told it may damage the floor cause of the weight (dynamic weight) my house is 30 years old. Did you face any issues? Thanks
