About Horizon T51 Treadmill

If you want a treadmill that’s affordable and has top-rated features, the Horizon T51 can be a great option. As an entry-level treadmill, the Horizon T51 is rather a solid-built machine. It has a heavy-gauge steel frame, meaning that it remains stable during intense exercises. It folds up to 72″ long and 56″ wide, and 48″ high and folds up quietly and smoothly without straining.

With its low price tag, the T51 doesn’t disappoint its users and has much to offer. The best thing about this treadmill is that it has several features only found on more expensive treadmills. With this treadmill, you will enjoy the convenience of a powerful motor, pre-programmed personal trainer workouts, backlit displays, a built-in fan, a folding design, and incline and speed levels.

This treadmill measures 67″ x56″ x48″ and weighs 175 pounds but can support users of up to 275 lbs in weight. The T51 treadmill brings a great entry-level unit to the offerings and is specially designed to suit walkers and joggers with a maximum speed of up to 10 MPH and an incline of 10%. If you live in the most space-deprived house, this model will suit all your needs.

Additionally, the Horizon treadmill comes with an integrated water bottle holder and a display to help you monitor your workout data. This model also has a contact heart rate monitor to help you track your heart rate while working out.

What I Like:


The Horizon T51 has a folding design that sets it apart from the other treadmills in the same category. It has a solid deck that feels stable when walking or jogging. The deck is well-cushioned to help absorb impact when exercising. However, this cushioning may not be enough for intense running, but it’s sufficient for walking. Although the tread belt is long enough to suit joggers and walkers, it may be a bit short for taller guys or those who love intense running and fast speeds.


The Horizon T51 comes with a blue backlit LCD screen that allows you to monitor your distance, time, calories burned, speed, and heart rate. With this treadmill, you will enjoy the convenience of a built-in fan that gives you a comfortable workout environment. The folding capability of this treadmill is one of its most outstanding features. This treadmill is easy to fold and will save on space. It also comes with a unique cushioning system that guarantees ultimate support, comfort, and stability.
