Its upright storage design and app-based workout recording suit home users short on floor space, though the listing gives a maximum user weight of 110 kg and customer feedback on reliability and build is mixed.

Pros and cons

Pros

A 121 cm by 46 cm running belt is described, giving more room than a compact walking-only deck.
The deck folds upright for storage, and the listing says it can be stowed without moving in most cases.
The treadmill can be operated without pairing it to the app.
A detachable phone and tablet holder and an emergency stop cable are listed among the included components.

Cons

The handlebar does not fold or adjust, so it remains part of the stored footprint.
At 37 kg, the treadmill is relatively weighty to reposition, despite the described transport wheels.
The stated 110 kg maximum user weight may rule it out for some buyers, despite the title's heavy-people wording.

What to know before buying

Listing details to confirm

The listing gives conflicting motor figures: 2 Horsepower as maximum horsepower and 1.25 Horsepower as input power, while its feature copy separately claims a 1HP brushless motor. It also calls the display LCD in one field and HD LED in feature text. The listed folded dimensions, 39.6 x 27.99 8.86 inches, are unclear as written, and the title's heavy-people wording should be weighed against the stated 110 kg maximum recommendation. Confirm the selected listing's details before purchase.

Customer feedback is favourable about compactness and folding, with some describing the treadmill as fitting its storage space well. Reports about reliability, noise, build quality, weight and value are mixed, including both reports of dependable use and reports of the unit stopping. That matters for a 37 kg treadmill intended to fold away: convenient storage is a reported strength, but buyers should not assume quiet operation or consistent long-term reliability from the listing claims. The overall rating distribution is mostly positive but includes a meaningful spread of lower ratings, so it does not settle those mixed concerns.

Yes. The listing says pairing with the KS Fit app is optional and that the treadmill can be switched on without using it.

How much user weight does the listing recommend?

The listed maximum weight recommendation is 110 Kilograms. The title describes it as being for heavy people, so use the stated limit rather than the title wording when checking suitability.
