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-7, 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 2.5 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.

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.

Running is rated yes on manufacturer figures: 20 km/h top speed on a 145 x 51 cm running area, which accommodates a running stride. Walking is comfortably within that. Apartment is limited rather than yes - at 85 kg with a 2.5 CHP brush motor this is a substantial machine, and no noise figure is published to support a stronger claim. Storage is limited: it folds, but the folded height of 159 cm is greater than its 140 cm assembled height, so it does not go under anything and still occupies 120 x 88 cm of floor.

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 145 cm or longer

Also folds to 120 cm deep or less
