Our Take
The JLL S300 is a motorised folding treadmill aimed at home users who want a compact, budget-friendly option for walking, jogging, and light running. It sits in the entry-to-mid-level segment of the UK home treadmill market, competing with similar fold-flat machines from Reebok and Roger Black, and suits flats or smaller homes where storage space is limited.
Key Features
Motorised belt with a speed range running from approximately 1 to 16 km/h
Manual incline adjustment with multiple gradient settings (typically three to six positions)
Fold-flat deck design for upright storage when not in use
Built-in console displaying speed, time, distance, calories, and pulse
Hand-grip heart rate sensors integrated into the handlebars
Multiple preset workout programmes to vary session intensity
Our Verdict
A sensible pick for walkers or light joggers in smaller homes who want motorised convenience without a large outlay. If you plan to run regularly at pace, or want a machine that'll withstand daily hard use, you'd be better served spending more on a heavier-duty model.
