How long will the Spirit CT850ENT last?

The Spirit CT850ENT has piggybacked in on the CT850 design and added a few bells and whistles to compensate for the upgraded price. This durable commercial-grade equipment will last a moderate to heavy user for years to come due to its high strength, heavy gauge frame and durable powder-coat paint. This is a great treadmill for those who want to go beyond what's expected and this sturdy, durable model will withstand even your most dedicated runs with ease!

Brief Overview

The Spirit CT850ENT Treadmill is a commercial-grade, powerful treadmill that can handle running or walking with effortless straightforwardness. The 4HP AC Drive motor provides enough power for whichever your preference may be, and the non-folding platform base ensures it will stand up under heavy use from both homeowners as well as commercial users looking to stay in great shape. If you are on a limited budget, we suggest looking elsewhere as this is a pricey high-end commercial treadmill.

Overall Quality

For those looking for a commercial grade treadmill, the Spirit CT850ENT is a decent choice. The large 15.6" touchscreen with TV and music streaming allow you to stay entertained while working out or watching your favorite show or YouTube videos. You'll also love that it has quick speed and incline keys so you can save time during each workout session without sacrificing results. There are dual drive motor cooling fans to protect both the control board and the motor from overheating as well keep them running smoothly at optimal performance levels. A spacious 22”x 60” workout area accommodates short to tall individuals comfortably who want maximum stability while achieving optimal results. This functional running machine comes equipped with a 4hp continuous duty motor; it can run smoothly on a variety of pretend terrains without slowing you down. The non-folding base allows this model to stand up against frequent use while maintaining stability throughout any workout session - no matter how intense they become. The Spirit CT850ENT has a plethora of features that make it a great choice for people with all levels of experience whether they are in a residential or commercial setting. Then again, this treadmill also includes a 3” diameter roller on the heavy-duty frame, 6 evenly distributed cushions, and a reversible deck that can be flipped to the other side to extend the life of the treadmill. You can even purchase extended arms to increase the stability. Training with heart rate monitoring is more effective and efficient and the CT850ENT offers pulse sensors that are ergonomically designed help you stay motivated by tracking your progress during a workout… just do not grab them too tight and expect them to hold up heavy weight users (they are not handrails) as we have replaced many plastic grips due to cracking issues. The frame comes with a lifetime warranty, there is 5-years for the motor, deck, and parts, 3-years console, and 2 years labor.

Buying a product that is worth the cost should be straightforward, but that is not always the case and here with the Spirit CT850ENT the cost seems steep at first glance when weighed against other treadmills in the similar price range. Despite the high price, the CT850ENT is a sturdy offering in the lineup of today’s treadmill offerings.
