Frame and deck

The Horizon T101-04 is a treadmill rated for a maximum user capacity of 300 lbs (136 kg). So, needless to say, it’s built on a solid, steel frame. All the steel parts in its construction feature a high-grade powder coating finish, resistant to scratching and corrosion. The horizon fitness t101-04 - folding framefinish of the base frame is black, while the finish on the upright console masts is gray. The side rail covers, the motor casing, and the console support are made of heavy-duty PVC material.

Like most treadmills in this feature range, the Horizon T101-04 is fairly heavy; it weighs approx. 165 lbs (75 kg) when fully assembled, its deck carrying most of the weight. Therefore, it’s recommended to be transported, unboxed and assembled by at least two people. On the other hand, its bases integrate wheels, both at the rear and at the front. So, its transport and relocation once it is assembled, shouldn’t be a problem.

The base of the machine is fairly large; it takes 70″L x 33.5″W (178 x 85 cm). On top of that, just as any other treadmill, it requires at least two feet of clearance on each side, and at least three feet of clearance at the rear, for safe operation. So, these being said, it may not be the best choice for a cardio training machine, if space is an issue. In this case, you might want to consider an indoor cycling bike, such as the Sunny ASUNA 5100 or IRONMAN H-Class 520.

On the other hand, this Horizon treadmill features a folding frame. The deck folds up, its folding being assisted by two hydraulic shocks when lowering it or raising it. With the deck folded up, the machine’s length is reduced to 45.5″ (116 cm), while its height becomes approx. 61″ (155 cm).

This treadmill can deliver speeds up to 10 MPH, while its deck can support running workouts with no problem. However, the running surface is designed for walking and jogging workouts, as it’s only 55″L x 20″W (140 x 51 cm). Therefore, taller users, over 6’2″ – 6’3″ may feel their movement a bit restricted if they undertake a running workout. horizon fitness t101-04 - 3-zone variable response deck

Nonetheless, the deck integrates a 6-cell cushioning system (3 on each side), being more flexible at the front where your foot lands, and firmer at the rear where you push off. This results in a workout with up to 30% less impact on your joints, reducing workout related paint, and leading to longer and safer workouts. Differently put, a run or jog on the running surface supplied by this Horizon treadmill is considerably more forgiving than a run on asphalt or concrete.

The running surface integrates a 2-ply, 1.4mm rubber belt, resistant to stretching, a belt which delivers an excellent adherence to just about any type of running shoes. The belt runs over two medium-sized rollers, 1.8″ at the front, and 1.66″ at the rear. The rollers are crowned and integrated high-grade, stainless steel, sealed ball bearings for smooth operation and a lifetime long lifespan.

Step-up height & incline

The step-up height of the Horizon T101 is approx. 9″ (24 cm). Also, by setting the incline to its maximum 10% setting, the front of the deck will raise by several inches. Therefore, in order to avoid any ceiling height issues, make sure that the ceiling height in the room horizon t101 - 10% inclinewhere you’ll be using the machine is at least 20″ (51 cm) higher than your own height.

This treadmill is equipped with a motorized incline system, consisting of a small motor and lift, situated at the front of the deck. It offers 10 levels of incline from 1% to 10%, the incline increments being 1%. The incline function of the machine adds a lot of diversity to the workout spectrum. Even though 10% incline isn’t that much, it can still considerably boost the intensity of your workout, providing a much higher burn.

Evidently, since the machine’s incline is motorized, it can only be adjusted from the console. There are quick keys for incline adjustment on the left side of the control panel, but the incline can also be adjusted gradually, from the Up/Down arrow keys near safety key.


The Horizon T101-04 is equipped with a 2.25 CHP. In other words, it’s a motor designed to support walking and jogging workouts. However, since the speed range provided by it is 0.5 to 10 MPH, it can definitely deliver running workouts. horizon fitness t101-04 - treadmill motor

This particular motor is designed for prolonged use, with a superlative continuous duty power, able to last without heating or slowing down even through the toughest workouts. It has a dynamically spin-balanced assembly, built with top-quality components, a motor to last a lifetime. That’s exactly why the warranty for this particular part of this treadmill is supplied for a lifetime.

As we’ve mentioned above, the speed range provided by this motor is 0.5 to 10 MPH. Differently put, its starting speed is 0.5 MPH. However, from there and up, the speed can be adjusted in increments of 0.1 MPH. The console features keys for gradual adjustment (near the safety key), and keys for quick adjustment, for the all the speed levels between 1 and 10.

Since it’s a motorized treadmill, it requires being connected to a power circuit of 110-120V. A power cord with a plug (not an adapter) is included, the plug being the U.S. standard 3-prong type.

The motor itself does not generate a lot of noise. But just as for other treadmills, the cadence sound generated during a running session on it is not to be neglected. Although it may not cover the sound of your TV, it may still be heard by the other members of the household, or the neighbors, if you live in an apartment building.


The console unit supplied with the Horizon T101 is similar in terms of built-in workouts with the one of the AFG 2.7AT. It basically has the same 30 workouts, divided into 5 categories: horizon t101-04 - console

Apart from the fitness-oriented features, the console of the Horizon Fitness T101-04 integrates several other features. Among these, we can mention a sound system, a cooling fan, two accessory pockets and reading rack.

The sound system consists of two large speakers, one on each side of the unit’s LCD. It’s compatible with most MP3 players, smartphones or tablets. The sound rendered by it is definitely superior to the sound generated by most tablet or phone integrated speakers. The two accessory trays are situated under the speakers; they’re large and deep enough to serve as bottle holders as well.

The workout fan, although not a powerful one, does offer some cooling during a more intense workout. It only has an On/Off setting, and not multiple speed settings. And finally, the tablet tray is placed right above the fan casing, being large enough to accommodate any tablet.
