A short belt shortens your stride and puts the back edge closer than you think. Published belt sizes here: 43.3 by 15.5 inches on the HitGo, 41.1 by 16.1 on one Sunny pad, 45.7 by 16 on the other. Two machines publish a width but not a length, and two publish neither — on a walking pad, which is remarkable.
And then there is the specification most listings bury. Sunny publishes a minimumuser weight of 99 lb for the Pacer Treadpad, printed on its own spec table beside the 265 lb maximum. For a frail or very small user — which describes a real portion of this audience — that is the maker saying the machine is not for them. It is published, it is findable, and no roundup we read mentioned it.
Maximum capacities here run from 245 lb to 300 lb, with the two Sunny pads at 245 lb and 265 lb. One machine publishes no capacity at all despite costing the most.
If those ceilings are the reason you are reading this, the high-capacity shortlist goes further up the range — including the one maker that publishes a sustained capacity as well as a peak, and the one whose listing states two different capacities in the same breath.
