A motor rating, a belt you actually run on, and a folded height
A treadmill is sold on horsepower and lived with on belt size. The motor figure to look for is the continuous rating, not the peak — peak power is a number the motor can hold for seconds, and a listing that quotes only the peak is telling you which number is smaller. Under-desk walking pads sit at the bottom of this range and are a genuinely different product: no handrail, low top speed, designed for 5 km/h and not for running. The figure that decides whether a treadmill can be run on is the running surface, published as length × width in centimetres. Under about 120 cm of belt length, a running stride does not fit, and the machine is a walking pad with a handrail whatever the speed dial says. Then top speed and incline, both straightforward, with the caveat that incline on a folding frame is often manual rather than motorised and the listing does not always say so. Published user weight is the load rating, and on treadmills it is the figure most closely tied to build quality. Cushioning is described far more often than it is measured; treat the words as a description of the design, not as a claim about joints. And the two figures that decide whether it stays in the room: the folded footprint, and the noise, which very few makers put a number on. We compare running surface, motor rating, rating basis, top speed, incline range, max user weight, folded size and rear clearance.
1.0–6.1 km/h, 100 kg, 47.2 × 19.6 × 4.6 in
A flat under-desk pad with a top speed of 6.1 km/h and a published thickness of 4.6 inches. The speed range is the honest statement of what it is for.
Best for: Walking at a desk in a room where the machine has to disappear
Belt 43 × 153 cm, 2.5 HP, 12 km/h
The machine in this family with the longest published belt: 153 cm by 43 cm, which is the figure that separates a running machine from a walking one.
Best for: Running rather than walking, where belt length decides it
40 % incline, upright handrails, folded 145.5 × 62 × 15.5 cm
The steepest incline in this family by a wide margin — 40 %, manually set — with upright handrails designed for it and a published folded size.
Best for: Incline walking where the gradient is the whole point
Belt 100 × 40 cm, pole 820–1150 mm, 29.5 kg
The machine that publishes both its belt and its handle height range: a 100 × 40 cm surface and a pole extending from 820 to 1150 mm, with a rotating angle.
Best for: A household where more than one person of different heights uses it
1–10 km/h, 15 % incline, 2.75 HP, 159 kg
A folding machine with a 15 % incline and a 2.75 HP brushless motor, rated at 159 kg — and a published noise figure of under 45 dB, which almost nothing here gives.
Best for: A flat where the noise figure matters as much as the speed
1–12 km/h, 9 % incline, 2.75 HP, 120 × 56 × 13.5 cm
A folding machine that publishes its own dimensions and a five-year warranty, with a 9 % incline, twelve programmes and a seven-layer belt.
Best for: Somebody weighing the warranty as heavily as the specification
10 % incline, 150 kg, folds sideways saving 75 %
A walking pad that folds sideways rather than upwards, saving a published 75 % of its footprint, with a 10 % incline and silicone oil supplied in the box.
Best for: Somebody who wants the maintenance consumable in the box from the start
10 km/h, Q235 steel, 25 kg, 6 dampers
A folding pad that publishes the grade of its steel — Q235 — and its own mass at 25 kg. Two specific claims on a shelf that mostly offers adjectives.
Best for: Somebody who wants the material named rather than described
Electric incline to 18 %, 3.0 HP, folded 114 × 59.7 × 13.7 cm
The only machine here with an electric incline, adjustable to 18 % without stopping, driven by a 3.0 HP brushless motor — the largest figure in this family.
Best for: Interval work where the gradient has to change without stopping
Only the specifications at least four models out of five state. A column that is more empty than full compares nothing.
