Strength, Motor, and Design:

The aesthetically designed heavy-duty steel frame and large steel console masts contribute to the ultimate stability of the treadmill. The durable powder coat finish of the frame not only makes it the best fit for your interior but also increases the life of the frame. The smooth continuous power required by such a heavy-duty treadmill is provided by high-end motor technology. The 4HP AC drive Motor is H grade isolated to reduce power losses and breakdown, and its durable construction has led to an industrial quality warranty. This commercial quality warranty on the motor tells you all you need to know about its quality and efficiency.

Modern Features and Programs:

All Spirit Fitness models enable nearly endless workout customization. The CT850 Treadmill has 16 pre-built programs, including fat burn, cardio, fitness tests, HIIT, manual, hill, and interval training workouts. Apart from these amazing built-in workouts, the treadmill also allows you to create unlimited custom programs.

You can create your custom program according to your preferred speed and incline. Also, heart rate monitoring and pulse monitoring have been integrated into the treadmill, and with the telemetric heart rate monitoring (chest strap sold separately) it allows you to work out in an effective training zone.

Cool Running Surface:

The wax-coated belt and the multi-ply rollers contribute to smooth, and uninterrupted running, whilst the hard wax deck system and the grade h insulation deck reduce the risk of wearing out. The CT850 treadmill can be used for years without maintenance. The cushioning systems of the Spirit Treadmills reduce joint stress and enhance shock absorption, and the double-sided cushioning throughout the unit ensures runners’ safety.


The Spirit CT850 treadmill comes with a commercial warranty of 5 years on motor, deck, and parts. A lifetime warranty on the frame and a two-year warranty on the labour is also extended by manufacturers. The residents of the UK can enjoy a lifetime frame, motor, and deck warranty. The residential warranty on parts and labour is 10 years and 2 years, respectively. The warranty may vary from one country to another.

*Warranty may be subject to change without notice and may differ between retailers – please check carefully before making a purchase.

Pros and Cons

Simple and Intuitive Console:

The console is divided into two convenient halves. The top control panel boasts a tri-color led display and direct speed and incline options. The LED displays the speed, incline, distance, pulse, heart rate, time, and intensity of the program. The console enables you to quickly program your workout according to your fitness levels and reach new goals. The simple and intuitive operation of the treadmill console includes quick speed, quick incline, preset programs, heart rate, and pulse monitoring. The console is perfectly placed at a level to accommodate tall individuals.

Convenient Features:

The Spirit Fitness CT850 Treadmill has many feasible features that make it a perfect fit for the commercial environment. The treadmill has a built-in fan to keep clients cool during running. Moreover, the treadmill is equipped with a tablet-friendly reading rack and a convenient water bottle holder to make your workouts even better. Also, you can play your favourite music and charge your smart devices through Bluetooth/audio jack or USB ports respectively.

Multiple Speed and Incline Adjustments:

The CT850 Treadmill has a startup speed of 0.3mph that increases up to 12mph, and you can make adjustments according to your preferred speed. The speed increment is about 0.1mph, or if you prefer, the treadmill has 5 preset speed buttons.

Also, the 0-15% incline can be adjusted to suit your preference. The incline increment of 0.5 % can be made, and just like the speed 5 preset keys for the incline are present on the console. You can adjust your workouts according to the maximum projected heart rate to remain in an optimal zone. The treadmill also provides handlebar controls for speed, and incline settings.

Emergency Stop Goes Off Randomly:

The emergency stop has, according to some users, gone off randomly, creating an interrupted workout (although I have to say I’m yet to witness this first-hand) Spirit Fitness has always promoted a safe and protected environment to work out in, and I’ve yet to personally have any issues with this (I just thought I should mention it to ensure this point was covered). All safety features are perfectly integrated into the treadmill
