Pros and cons

  • Pre-built: Already assembled.
  • Compact: Small and great for tight spaces.
  • Maximum speed of 16kph: As fast as some gym treadmills.
  • 18 training options: Including pre-set workouts, target-based sessions and a body fat test.
  • Ideal for beginners: Clear user interface and good basic functions.
  • Low noise: Quiet motor when in use.
  • Limited incline: Low incline settings.
  • Not advised for advanced runners: Offers only basic features and functions.
  • Not as stable as other models: Light frame means the treadmill bounces around more than other models.
  • Not the smoothest run: Limited cushioning system.

Provided you have a tablet in the home, then you can slip it into the holder and run through beautiful landscapes, stream your favourite shows or even check your emails (boo!). No tablet? Don’t panic – it’ll hold a smartphone just as well. Meanwhile the 4-window LED display will let you track your speed, distance, time, calories, pulse and step-count at the same time.
If your space is at a premium, then the I Run 4.0 has a lot going in its favour. You can opt to stow it away vertically (say, in a tall cupboard) or horizontally (say, under a table), and while some bulkier models actually don’t condense down that much when you fold them, the I Run 4.0 really does. When folded horizontally, its height is reduced from 156cm to an impressively-compact 31.5cm.

Expert review

The Reebok I Run series is one of the best-known, compact treadmill ranges on the market, and the 4.0 is no exception.

The model is built with home use in mind, it’s small, foldable and incredibly light, with integrated transport wheels for easy positioning. It’s also very quiet. So, if you don’t exactly have a spare room to set up a treadmill in full-time, this could be the purchase for you.

With a maximum speed of 16kph, plus 18 different training options to pick from (including a body fat test), it’s no slouch when it comes to helping you work up a sweat, either.

But this is not the machine for experienced pavement pounders. Its basic display screen, limited cushioning system and small incline setting is likely to frustrate the more advanced runners out there (perhaps check out Reebok’s Jet 200 and Jet 300 models). Instead, we recommend it for beginners with limited inside space – it does all the basics well, it’s super-compact and it comes in at a reasonable price.
