JTX Slim-Line: Compact Folding Treadmill



or from £25/month
Flat folding treadmill with digital incline, 14kph top speed and 41 x 125cm running deck.

A Flat Folding Ultimate Space Saver

We have developed the JTX Slim-Line: folding treadmill because we understand that not everyone wanting to train at home has space for a home gym. The JTX Slim-Line is our most compact treadmill and is the ultimate space saver. It folds away completely flat so you can store it under a bed or neatly in a cupboard. To ensure maximum flexibility it is fitted with two sets of storage wheels: in the upright position, you can wheel it forwards or sideways, giving this compact treadmill the ultimate home training flexibility.

15 Levels of Power Incline

Unlike most other foldable treadmills, the JTX Slim-Line features 15 levels of power incline. This means you can effectively work your cardio system, calves, hamstrings and glutes. The incline also enables a greater range of workouts such as hill climbing and interval training. Keeping your workouts varied is a great way to keep you motivated and training towards your goals.

DiscTech™ Speed Adjustments

For increased safety and efficiency, the JTX Slim-Line: folding treadmill features speed disc adjustment. Quickly and intuitively adjust your speed without looking down with a swipe of the finger on the JTX DiscTech™ system.

41 x 125cm Running Deck

The JTX Slim-Line features a genuinely usable workout area. While not suitable for high performance training, this is a fantastic workout area for those looking to improve their fitness from the comfort of their own home.

Emergency Stop Button

The emergency stop button allows you to focus on your training safe in the knowledge you can stop the treadmill instantly in the event of a problem.

Special Offer

For a limited time we are offering free personalised training plans to help our customers achieve their goals faster. Now with FREE hand weights to improve calorie burn and tone upper body. See our special offer tab for more details.

No Assembly Required

The JTX Slim-Line comes ready-assembled in the box. It is delivered in the storage position, ready to go. Simply remove from the box, set it in the training position, plug it in and start running! It really is home training simplicity from the moment you open the box.

14kph Top Speed

While not a high performance treadmill, a 14kph top speed ensures that this fold away treadmill packs a great punch for its size. Jogging and speed walking are the JTX Slim-Line’s bread and butter. The JTX Slim-Line combines these speeds with power incline to ensure it is a truly effective compact treadmill.

Digital Display with 7 Programs

The JTX Slim-Line features a large, easy to read digital display that tracks the key metrics of time, distance, speed and calories burnt. The computer features 6 pre-programmed workouts that take advantage of the power incline. The user defined program allows you to create a bespoke routine perfectly aligned with your fitness goals.

1.5HP Motor

The JTX Slim-Line’s 1.5HP motor further demonstrates that this fold away treadmill is no gimmick. This high grade motor will help guarantee that this machine will keep going as long as you do!

Treadmill Terminology

The tilt of the running deck that simulates uphill running. Some entry level treadmill will feature a "manual incline" feature. This means you have to manually adjust the incline when you are not on the machine. "Power incline" is a term often used to described automatic incline that is controlled via buttons or a disc as you train. We would not recommend a treadmill with manual incline.

The moving belt which you run on. This is also called a "running deck".

This refers to a treadmill containing electric motors that move and tilt the deck for you as you walk or run. It is a term often used to differentiate itself from the cheap, "manual treadmill" alternative. A manual treadmill operate by pushing the conveyor belt with your feet (not recommended).
