The JLL S300 is a folding treadmill that the whole family can enjoy and comes with the lowest starting speed I’ve seen available in the UK of 0.3 km/h.

This is particularly important if you’re older or recovering from an injury where a faster start might cause you to stumble.

But before we dive into the features and performance section of our JLL S300 folding treadmill review, let’s take a look at some of the standout specifications.

JLL S300 Treadmill Key Specifications

  • Motor: Peak power of 4.5 HP and continuous power of 2.5 HP
  • Speed Range: 0.3km/h – 16km/h
  • Programs: 3 programmable and 15 pre-programmed workouts are available
  • Incline: Auto power incline up to 12 percent with 20 different levels present
  • Large LCD: Display speed, time, distance and more plus built-in speakers
  • Warranty: 2 years on parts and (an impressive) 5 years on the motor
  • Max User Weight: 120kg

JLL S300 Features and Performance

The LCD monitor display of a digital folding treadmill not only includes your current run statistics, but it also comes with 15 preset running workout programs to get you started.

You can also create your own workouts with three programs you can customise to your own needs.

A Digital Folding Treadmill LCD display includes: Time, Speed, Heart rate, Calories burned, Incline and Distance run.

You can also connect your device audio directly to the JLL S300 Treadmill speakers either with the USB or auxiliary (headphone jack) slots available.

JLL300 Speed and Incline Levels Options

Boasted as the slowest starting speed in the UK. The JLL Treadmill S300 offers a very smooth start of 0.3 km which is great for an easy warmup or for older users focusing on gentle walking.

As you progress, you can increase the speed up to 16 km for a very fast run.

An incline setting is available that will allow you to change the incline between 20 different levels of difficulty. This JLL S300 running machine allows for up to 4 times the calorie burn when on the highest level setting.

JLL S300 Delivery and Assembly

The shipping was great, but the instructions (as usual) left a little to be desired during assembly. I recommend you have another person help you with assembly so one can hold the parts in place while the other attaches them.

However once assembled, this machine is very stable and seems very durable.

Size and Weight of JLL S300

The JLL S300 folding treadmill has the following weight and dimensions:

  • Assembled Dimensions: (L x W x H) 1580 x700 x 1280mm
  • Folded Dimensions: (L x W x H) 1000 x 700 x 1500mm
  • Boxed Dimensions: (L x W x H) 1700 x 760 x 305mm

  • Assembled weight: 57.5kg

Smooth Running with Suspension System of JLL S300

As your feet hit the treadmill’s running deck, they will trigger the 16-point cushioning system underneath.

This dampens the noise of your foot hitting the running deck, and makes it a little easier on your knees. 

This is one of the features you start seeing when you invest a little more in your JLL S300 treadmill.

Conclusion on JLL 300 Treadmill Review & Overall Value

JLL S300 Digital Folding Treadmill, 2024 New Generation Digital Control 4.5HP Motor, 20 Incline Levels, 0.3km/h - 16km/h, 15 Professional Programs, 2-Year Parts & Labour, 5-Year Motor Cover

Pros

  • Excellent Speed range both slow (0.3 km/h) and fast (16km/h)
  • Soft running platform with advanced cushioning system
  • Good variety of pre-programmed and customisable workouts
  • Long warranty – 2-years on parts and labout, 5-years on the motor

Cons

  • Poor assembly instructions (as usual for most treadmills)
  • Folded size is still quite large (a common problem on better treadmills)

The running experience on the JLL S300 is pretty spectacular for the price.

You have a range of features and speeds you can work up to in an effort to burn more calories as your fitness improves. It a treadmill that you can stay with for many years. 

My final assessment for this JLL S300 digital Folding Treadmill is that it comes with many premium features, is easily programmable and offers excellent durability with an impressive build quality.

I'm Jamie and I test out new models in sports retailers, or buy and sell them new or second hand so I can review a wide range of models and put together the best advise on which treadmill is right for you. So if you are looking for a cheap treadmill for walking, a gym quality treadmill to run sprints, or something in-between I can point you in the right direction.
