The Jet 300 is not one of the newest Reebok treadmills. It’s one of the models released in 2017, but it’s still available. In terms of design, it is similar to the Reebok Jet 100 model that we’ve already reviewed here. However, this model is heavier, offers a larger running surface, it’s equipped with a more powerful motor and offers a few other extra features.

Frame and deck

The Reebok Jet 300 offers a pretty sturdy construction with a deck designed to support a maximum user weight capacity of 308 lbs (140 kg). Its frame is made of steel tubing, but the machine does integrate several hard ABS plastic parts. For example, the side rail covers, the covers of the motors, and the console dashboard are made of ABS plastic.

All the steel parts in the machine’s construction are coated with a corrosion-resistant paint finish. As opposed to the Jet 100 model, the color used for the Jet 300 model is black, with the “Reebok” logo painted white. These are the only colors available for this model.

As we’ve mentioned above, this treadmill is slightly larger than the Jet 100 model. It is approx. 76″ (192 cm) long, and 34″ (86 cm) wide. Plus, it is recommended to allow at least two feet of clearance on each side of the deck and at least three feet of clearance at its rear for safe usage.

On the other hand, this Reebok treadmill has a folding design. Its deck can be folded up to save space, and with it folded up, the unit’s length is reduced to approx. 49″ (124 cm). The folding mechanism is hydraulic; it consists of a cylinder that slowly lowers the deck when it is unfolded, to prevent damage.

The fully assembled treadmill is fairly heavy. It weighs approx. 192 lbs (87 kg). Needless to say, this weight delivers excellent stability. Despite its weight, the unit is easy to move as its front base is equipped with transport wheels.

The Reebok Jet 300 treadmill offers a running surface of 59″ (150 cm) long, and 20″ (51 cm) wide. Therefore, it can accommodate users up to 6’3″ – 6’4″ (190 – 193 cm) with no problem, allowing a complete range of motion.

Like many other treadmills, the unit’s deck is cushioned. It is equipped with Air Motion cushioning technology. It features a set of cushioning elements on each side, placed under the front half of the deck in order to absorb a part of the shock for each foot strike. The rear part also has two concealed shock absorption elements which provide a bit of boost for each foot push. These being said, running on this treadmill results in less impact stress on the joints, and therefore less workout-related joint pain.

Incline and step-up height

The Reebok Jet 300 treadmill features an automatic incline system. This means you can adjust the incline without interrupting your workout. Also, the console has built-in programs that can automatically adjust the incline depending on their setting.

The unit’s incline system consists of a small lift placed under the front of the deck and a motor that is different from the drive motor. As you adjust the incline, the motor controls the lift, raising or lowering the front part of the deck.

The machine makes available 15 incline levels. The incline can be adjusted in increments of 1%. There are keys for gradual adjustment and quick-adjustment on the console. The quick adjustment keys cover the 3, 6, 9, and 12 incline settings.

The Jet 300 treadmill has a deck step-up height of approx. 9″ (23 cm) above floor level. However, with the incline set at maximum, the front part is elevated by several inches. Therefore, it’s best to place and use the machine in a room with a ceiling that exceeds your own height by at least 16″ (41 cm).

Drive motor

The Reebok Jet 300 is equipped with a 2.5 HP motor. It’s not one of the most powerful motors, as some machines for home use offer up to 3.0 CHP in terms of motor. But nonetheless, it gets the job done. It offers a pretty decent speed range, and has an internal flywheel for motion stability.

The motor offers a speed range between 0.5 MPH and 12 MPH. Although the starting speed of the running belt is 0.6 MPH, the speed can be adjusted in increments of 0.1 MPH. This is quite a plus, as it allows you to find the perfect pace depending on your height and workout. The gradual speed adjustment keys have a double function, though. By pressing and holding them you can adjust the speed in increments of 0.5 MPH. Quick speed adjustment settings are also available on the console. They allow quick speed selection for 3, 5, 7, and 10 MPH.

Just as for incline, if you choose to exercise by using one of the onboard programs, the machine will auto-adjust the speed of the running belt. So, these being said, some of the programs will auto-adjust both the incline of the deck and the speed of the belt.

One last aspect to mention here regards power consumption. Since it’s not a super powerful motor, the machine’s power usage is also minimal. In other words, even if you will be using it daily, it shouldn’t add more than a few dollars to the electricity bill. Also, the motor itself doesn’t generate a lot of noise when in use, but depending on how fast you go, your cadence may generate more or less noise.


The Reebok Jet 300 features an LED display console. It is equipped with 7 LED displays which indicate incline, pulse, time, speed, calories, and distance, while the large one in the middle shows the profiles of the selected programs. There are both metric and English units settings for speed and distance. Also, distance can be viewed on the larger monitor as 1/4 mile (0.4 km) track.

The console unit is not telemetric. This means it cannot read your pulse via a wireless HR transmitter. However, the treadmill has built-in sensors in its front grips.

The console unit has 24 preset workout programs that automatically adjust the belt speed and deck incline. Each program is adjustable, though; you can change its time span, speed and incline for each segment. The P0 program is the manual mode which allows you to freely control speed and incline as you like during your workout. There are countdown settings available for the time, distance and calorie metrics.

Along with the preset programs, the machine also has goal settings for time, distance, and calories, three user-defined programs, and a bodyfat program.

Other notable features with regards to the machine’s console are a sound system, a cooling fan, a tablet holder, two bottle holder, and a USB port. The sound system consists of two speakers placed in the mid-section of the unit. It is compatible with any smartphone, tablet or MP3 player. You can connect your device to the treadmill console via AUX cable and play your music through the integrated speakers.

The cooling fan is located under the sound system section. It’s not a very strong fan, but does offer a bit of cooling if necessary, during a more intense workout. The tablet holder is placed between the two display sections. Therefore, if you place a tablet on it, the top displays will be covered by it. The USB port is placed on the right side of the console. It is only a charging port; it does not allow workout data transfer on a USB stick and the console is not compatible with any fitness apps. And finally, the console dashboard also integrates two bottle holders, one on each side.

Assembly and Maintenance

The treadmill’s deck with its motors, belt, rollers, and the two front masts come pre-assembled. You only have to unfold the two masts and lock them in an upright position, then connect and secure the console. This shouldn’t take more than 30-40 minutes of your time. The manual provides very clear assembly instructions and all the necessary tools are included.

For maintenance, belt lubrication is necessary. The manual also provides instructions on how to lubricate it. Other than this, you just have to keep the belt clean and periodically check for loose bolts and parts.
