JTX Sprint-3: Electric Treadmill Features

Convenience + Motivation = Daily Exercise

A small treadmill with a robust, reinforced steel frame and intuitive, easy to use computer. Use the power incline to boost the benefits of walking or to increase the intensity of your runs.

This electric treadmill is ideal for daily exercise to improve cardio health, aid weight management and reduce the risk of illness.


The JTX Sprint-3: Electric Treadmill is an incredibly durable small treadmill with a reinforced steel frame, highest-quality components and superior build quality. That’s why we guarantee your treadmill for 2 years. All parts and labour included. No-quibbles, just call our UK based customer support team.


In our Sussex-based head office, we work hard to ensure our customers are happy. Over the last 10 years, we’ve earned our reputation for outstanding service and products that delight our customers. We also offer free personalised fitness plans and outstanding support.


The spacious 129 x 46cm running deck defies the 'budget' feel of other small treadmills. The advanced CushionStep™ suspension technology can reduce the impact on your knees and joints by up to 30% compared to walking or running outdoors. You’ll feel the difference with this 8 point shock system.


Unlike other treadmills in its price range, the JTX Sprint-3: Electric Treadmill features a fully automatic incline. With the quick speed and incline buttons, you’ll be able to retain good form while quickly adjusting your workout.

The 12% automatic incline raises your treadmill through 12 levels, so you can increase the intensity of your workout- without increasing stress on your joints.


Our motor is surprisingly powerful for its size, giving you all the power you’ll need as your fitness levels increase.

The JTX Sprint-3: Electric Treadmill is designed to pack the most powerful components and advanced functionality into the robust frame of a small treadmill.


Features a built-in fan to keep you cool as you work out. The fan is controlled with the push of a console button.

Safety Key

The JTX Sprint-3 safety key allows you to focus on your training with the confidence that the motorised treadmill can be stopped instantly in the event of a problem.


We know that the key to using your treadmill regularly will be easy access. The JTX Sprint-3: Electric Treadmill can be wheeled to your location of choice, and the hydraulic assist running deck lowers softly and safely to the ground. When you’re done with your workout, the running deck folds up easily, making it easy to safely store your treadmill.

This treadmill does not fold completely flat, which allows for a more solid frame design. It has a 120kg maximum user weight.


When you’re keen to start working out on a new treadmill, you’ll want to get going straight away - not spend hours learning how to use it. So we’ve made the computer intuitive and easy to use.

On the 5” high-visibility backlit display you’ll also be able to view your speed, time, incline and distance. Keep track of how hard you are working with the calories indicator, and monitor your heart rate via the pulse sensor on the handlebar.

The start, stop, speed and incline buttons are all clearly marked, and are easy to press when you are running at speed.


You’ll have your new electric treadmill up and running in just three easy steps. It comes with a simple and clear user manual to guide you through each step, and our UK customer service team are available to answer any questions you may have.


With an impressive 40 workout programs, your training will be diverse and interesting, each and every time you train.


The ergonomically placed tablet holder, MP3 sockets and speakers will allow you to watch your favourite TV shows, listen to music and stream exercise classes, keeping you motivated.

For other interactive running experiences, you'll need a widget called a foot-pod attached to your trainers and an iPad or tablet. We recommend the Zwift Runpod, which is widely available online at about £30. You’ll be able to run through virtual worlds, join group races and explore beautiful real-life tracks.

Treadmill Terminology

The term ‘horsepower’ is a unit of measurement for motor size. A large horsepower of 3hp or more generally indicates a premium quality motor which will last longer than a smaller motor size. You will often see two horsepower measurements, continuous and peak. For example, 1.75 horsepower, 3 horsepower peak. We suggest you focus your attention on the continuous duty rating, which is the lower reading of the two.

Some lower-quality treadmills refer to their power in watts. There are 750 watts to 1 horsepower unit. If you are hoping to run over 3 times per week, or you weigh over 10 stones, we recommend looking for a treadmill with at least 1.5 horsepower.

Also known as the "running deck", this is the moving belt that you run on. We recommend you buy a large treadmill with the biggest belt that you can fit in your home. This will allow you plenty of room to sprint without feeling restricted.
