When assembled, the treadmill measures up to 25 x 45 x 58 inches.

Quick Navigation


It must be stated however that the Merax JK1603E Folding Electric Treadmill comes with a motor that has a peak performance power of 500 Watts and can cause the conveyer belt to go on a range between the speeds of 1 KM/H for a slow walk to 10 KM/H of moderate level running. The motor surprisingly makes very little noise and affirms that you can freely do your treadmill work-out without your house/apartment members complaining about it being too noisy.

The LCD is a multi-functional display which can track progress in speed, distance, heart-rate, and calories burned. It also comes with 3 pre-installed workout programs that can border from low intensity workout programs to high intensity workout programs. All 3 workout programs have been configured based on the workout regimes assigned by personal trainers. The treadmill also comes with 3 inclination options which means that you can easily walk or jog on a level surface yet can also increase the slop in two further angles in order to increase the intensity and difficulty level of the workout. But the configuration of the slops is not linked to the control panel and so you will have to get off the treadmill and manually adjust the angle of inclination every time the situation calls upon you to do so.

The treadmill also has a safety key which automatically shuts off the treadmill whenever the key is disconnected. This ensures that if in case the treadmill doesn’t turn off by the button (a hypothetical situation that we are only considering for the sake of caution), you can pluck out the safety key and lo behold the treadmill will come to a gradual stop. You can therefore safely practice your workout without fear of being imbalanced or tripping over. You can also hold on to the foam coated and double grip handlebars for extra balance.
The running track measures up to 14 x 44 inches which might prove to be a little short for those who have longer running strides which means that the treadmill is best used for brisk walks and light jogging. The running track however is also cushioned which means that there will be less stress on your knee and ankle joints, which in turn would help your muscles fastly recuperate themselves after a workout.
