Who should pick which

Pick the Echelon Stride DuoTread if

you are tall or walk briskly. Its 43.3-inch belt suits walkers up to about 6'4" at slow desk pace (5'1" with 6 inches of room to drift), though it is short for brisk walking by our rule, against 5'11" at slow desk pace on the 41.3-inch belt.
you also want to jog or run. It reaches 7.5 mph against 4 mph.
you want something to hold for balance, for example at faster speeds or on incline.

Pick the Merach W50 if

you weigh more than about 245 lb. It is rated for 400 lb against 275 lb, and we suggest 30 lb of headroom above your weight.
you want to walk uphill. It has motorized incline up to 12%, while the Echelon Stride DuoTread only has manual incline.
you want to change speed without bending down to a console.
budget matters most. It sits in the mid-range 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.
