Who should pick which

Pick the DeerRun X20 if

  • you weigh more than about 190 lb. It is rated for 400 lb against 220 lb, and we suggest 30 lb of headroom above your weight.
  • you want to walk uphill. It has motorized incline up to 15%, while the Sunny SF-T1407M Manual Walking Treadmill only has fixed incline.
  • you want to change speed without bending down to a console.

Pick the Sunny SF-T1407M Manual Walking Treadmill if

  • you need to know the belt length before you buy: the other model does not publish one.
  • you will move it in and out of storage often. It weighs 46.7 lb against 87.83 lb.
  • storage space is tight. It folds (yes, deck folds up); the other one does not fold its deck.
  • budget matters most. It sits in the budget tier.

Our buying guides

How these pages are built

Every figure comes from the maker's product page, manual or the Amazon listing, and we only include models with a live, in-stock Amazon listing we checked ourselves. When sources disagree on a weight limit we use the lowest number. We do not test these machines ourselves.

Height fit starts from a typical walking step of 0.41 times your height (0.45 when walking briskly), adds 12 inches for your shoe, and 6 more inches of room to drift for a comfortable fit. These are rough guides, not measurements of you. Weight fit leaves 30 lb of headroom above your body weight.
