We have not run on this machine and we do not pretend to have. What follows is every figure JTX or its retailer publishes about the JTX Sprint-8 Pro, each one carrying where it came from and when we checked it, and an equally plain list of the 2 figures nobody publishes at all.

What the figures say

Every line below is worked out from the numbers in the table, compared against the other machines we hold records for. None of it is an impression.

In its favour

  • Incline reaches 12%, enough to make a walk hard work.
  • The motor figure is published as 3 CHP, continuous rather than peak. Most brands leave you guessing which one they mean.

Against it

  • The 130 kg ceiling is below the 182 kg of the highest-rated machine we hold.
  • At 117 kg it is a two-person lift, and it is not going upstairs easily.

What nobody publishes

Most sites leave these rows out, which makes a machine look better documented than it is. They are here because knowing what is unknown changes how much weight you put on the rest.

Who it suits

Our reading of the figures above, not a verdict on the machine.

No
Putting it away
Up to a point

Running is yes - 20 km/h on a 153 x 55 cm area, the largest running surface in this round. Apartment is no on mass and permanence: 117 kg and ground-floor delivery only. Storage is limited rather than no because it does fold, but folding raises it to 156 cm and still leaves a 132 x 90 cm footprint, so it frees floor space without letting the machine be put away.

How this page was put together

Every figure above was read off a named source, recorded with the date we read it, and is shown with that source attached. Where two sources disagreed we kept both. Where a figure was missing we left it missing, because the alternative is to borrow a number from a similar model and hope. Nothing here is a measurement of ours. How we review.

Where to go from here

Also rated for 130 kg or more

Also a deck of 153 cm or longer

Also folds to 132 cm deep or less
