Who should pick which

Pick the Goplus Superfit 4.75HP 2-in-1 if

  • you drift sideways while you read or type. A 20-inch belt gives more room than 18.1 inches.
  • you also want to jog or run. It reaches 10.5 mph against 7.5 mph.
  • you want to change speed without bending down to a console.
  • budget matters most. It sits in the mid-range tier.

Pick the WalkingPad X21 if

  • you will move it in and out of storage often. It weighs 81 lb against 106 lb.
  • storage space is tight. It folds (Yes, double fold); the other one does not fold its deck.

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.
