JLL S300 (2019) Treadmill Review – 16 km/h and 5-year Motor Warranty

Last Updated on

​The JLL S300 is a 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. ​

JLL300 Speed and Incline Options

Boasted as the slowest starting speed in the UK. The JLL 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 allows for up to 4 times the calorie burn when on the highest level setting.

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

The S300 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
  • Running Deck Area (L x W): 1230 x 410mm
  • Boxed Weight: 70 Kg
  • ​Assembled weight: 57.5kg

​Smooth Running with Suspension System

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 treadmill.

​Conclusion on JLL 300 Overall Value

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.

JLL S300 Pros:

  • 20 level power adjust incline
  • 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

JLL S300 Cons:

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

​My final assessment for this JLL S300 treadmill is t​hat it comes with many premium features, is easily programmable and offers ​​excellent durability with an ​impressive build quality.

It is one of my favourite mid-range treadmills and I have personally recommended it to ​friends.
