Reebok has released several ZJET 430 products in 2019. We’ve already covered here the ZJET 430 upright bike and the ZJET 430 elliptical. So, in this post, we’re going to address the ZJET 430 treadmill. This is a machine made for home use but does offer an automatic incline system and 24 preset programs.

Frame and deck

The Reebok ZJET 430 treadmill is constructed on a steel frame, combining ovalized and rectangular bars for improved aesthetics. The front base bars have ABS covers for extra protection, as well as the side rails and the motor. All the steel tubes are coated with a corrosion-resistant paint; the color used is black for this model, with the “Reebok” logo painted white.

The fully assembled treadmill is not extremely large compared to other machines, such as the SOLE F63, for example. However, it does take approx. 68″L x 30″W (172 x 78 cm) of floor space. Plus, it is recommended to leave at least three feet of clearance at the rear of the deck, and at least two feet on each side for safe usage. Therefore, it may not fit too well in a small room.

On the other hand, this Reebok treadmill is foldable. Its deck can be folded up to save space. In folded position, the unit’s length is reduced to approx. 42″ (107 cm), while its height gains a few inches. The folding mechanism consists of a hydraulic cylinder which slowly lowers the deck when it is unfolded to prevent damage.

The front base of the treadmill rests on four adjustable levelers. The two lateral base bars integrate transport wheels which allow you to easily move the unit when it is folded. The rear base feet are also equipped with wheels, but these are meant to help only the deck’s transport in case you will ever have to remove it from the rest of the frame, or for improved stability.

The machine’s deck offers a running surface of approx. 51″L x 17″W (130 x 43 cm). This being said, the ZJET 430 treadmill may be a bit small for a user over 6’0″ (183 cm). But on the other hand, the deck is durable enough to support users up to 264 lbs (120 kg), which is not too bad for a home-use treadmill.

The running platform of the ZJET 430 treadmill is equipped with a Triple Flex cushioning system. It integrates three types of cushions. A set of two smaller cushions are placed at the rear of the deck for a better push-off. A set of large air cushions is placed under the front third of the deck for impact dispersion; these are visible on each side of the deck. And finally, on each side of the deck, there are two thicker rubber cushions placed one on each side of the air cushions. This being said, the treadmill’s deck is designed to absorb a great deal of the shock generated by each foot strike. This results in a more comfortable run and less workout-related joint pain.

Incline and step-up height

The Reebok ZJET 430 treadmill is equipped with a motorized incline system. This means you can adjust the incline as you walk or run. Also, the console can adjust the incline automatically.

The incline system consists of a separate motor from the drive motor and a small lift placed under the front of the deck. As you adjust the incline, or as the console automatically adjusts the incline, the lift slowly elevates the front of the deck.

The unit’s incline system makes available 12 distinct levels. The incline increments are 1% and the incline range is 0% – 12%. The incline can be adjusted gradually from the controls integrated into the left grip or the keys on the lower bottom left corner fo the console. However, the console also provides quick incline selection keys for the 3, 6, 9, and 12 incline levels.

With the incline set at 0%, the unit’s running surface is situated at approx. 8″ above floor level. By setting the incline to maximum, the front of the deck gains several extra inches. This being said, it is recommended to use this treadmill in a room with a ceiling height that is at least 15″ (38 cm) above your own height.


The Reebok ZJET 430 treadmill is equipped with a 2.0 HP motor. Evidently, it’s not a super powerful motor like the one on the SOLE TT9. But nonetheless, it still is a motor designed to support prolonged jogging or running sessions, even at full speed, without overheating or losing performance. It also integrates a small flywheel for improved belt stability and reduced vibration.

The machine’s motor provides a speed range between 0.6 MPH and 10 MPH. The speed adjustment increments are 0.1 MPH, so the transition between levels is done smoothly, giving you the possibility to adjust your pace with ease. Also, if the speed is set to km/h from the console, the speed adjustment increments are 1.0 km/h.

Just as for the incline, the machine makes available gradual speed controls and quick speed adjustment controls. There are gradual speed controls integrated into the right grip of the unit and on the bottom right corner of the console. The quick speed selection controls allow you to select 3, 4, 5, 7, 8, 10, 12, and 16 km/h (or 1.8, 2.4, 3.1, 4.3, 4.9, 6.2, 7.4, 10 MPH).

The machine’s console offers several programs; if you choose to exercise via one of these programs, the treadmill automatically adjusts the speed according to each segment of the workout in use.

The motor itself is fairly quiet. It doesn’t generate a lot of noise when in use, but when running at a higher speed, the thumping of your cadence will be heard. Also, since it’s a 2.0 HP motor, you won’t have to worry about a high electricity bill even if you use the machine daily.


This Reebok treadmill is equipped with a mid-range console. To begin with, it features a 5″ LCD display with LED backlight and large digits for improved readability. It indicates time, distance, speed, incline, steps, calories, and pulse. Speed and distance can be set either to Metric or English units. The distance is also shown in the middle of the display as a 1/4 mile (400 m) race track with a lap count reading.

The console does not have Bluetooth and it is not telemetric. It can only read your pulse if you hold on to the sensors integrated into the side grips. It cannot communicate with a wireless HR chest strap transmitter.

The console unit makes available a fairly decent selection of programs. First of all, it has the classic Manual program (P0) which gives you the possibility to adjust the speed and the incline as you like during your workout session. This program also makes available four target settings, for Time, Distance, Calories, and Steps.

The P1-P24 programs are all preset. They all control both the speed of the belt and the incline. The default workout time for each one is 10 minutes. This duration can be adjusted before the program is launched.

The console does not have a Target Heart Rate program but does offer a Body Fat Index function. This gives you the possibility to input your data such as age, height, weight, and gender, and based on it, you can calculate your Body Mass Index. This can help you keep a better track of your progress.

Other notable console features that we can mention here are the integrated sound system, the tablet holder, the USB port, and the two bottle holders. The sound system consists of two speakers placed between the console display and the main controls. It is compatible with most smartphones, tablets and MP3 players, so you can connect your device to it via AUX cable and play your music through these speakers for better sound quality.

The USB port is situated at the top of the console. It only fulfills the charging function for your device. You cannot save your workout data on a USB stick in order to transfer it online to a fitness app. The tablet holder consists of a shelf placed above the console display. And finally, the two bottle holders are molded into the ABS dashboard of the console; they’re spacious enough to support most hydration bottles.

Assembly and Maintenance

The treadmill’s deck with the motors comes pre-assembled. You only have to attach the two upright bars, the console, and several small covers. This shouldn’t take more than 30-40 minutes. All the necessary tools are included. Also, the manual provides pretty clear assembly instructions.

For maintenance, it is important to keep the belt clean, to prevent any debris or textile fibers to be caught into the motor or the rollers. The belt also requires periodic lubrication.
