Merax Folding Treadmill Buyers Guide

⦿ Speed

Before buying a treadmill, you should consider what kind of speeds you are comfortable running. Most treadmills under review here offer a speed range of 0.5-10MPH. However, some treadmills can reach up to 15MPH.

⦿ Horsepower

The higher the horsepower, the faster the treadmill can run. The least horsepower for joggers and walkers is 1.5HP. For running treadmills, you need at least 2.5-3.0HP.

While getting a machine with a low horsepower will still work fine, you risk motor failure or overheating when used for running at high speed and for a long time.

⦿ Console

The console is an important part of the treadmill as it lets you track your sessions by relaying real-time data. The console area is also designed to smooth your running experience by providing you with items you need while running.

Modern treadmills have consoles encouraging interactive training by connecting to a personal trainer using wireless connections like Bluetooth or the internet. In addition, there are many treadmill apps that you can subscribe to at a small monthly fee for personalized training sessions.

The console should be easy to read and use.

⦿ User Weight Capacity

Not all treadmills can support your weight. Some contend with less than 200 pounds, while others can tolerate up to 300 pounds. Budget treadmills don't support too much weight and can break if used regularly by someone who exceeds the weight limit.

⦿ Cushioning

Running on hard surfaces causes stress on your joints, knees, and ankles. However, running on a treadmill eliminates this possibility as most models have multi-layer running surfaces that enable you to run on the treadmill for longer.

Some recent models can turn off cushioning if you are a runner that wishes to run on the treadmill but wants the real road experience.

⦿ Incline

Running flat on a treadmill isn't as challenging as when running at the same speed but at an incline. If you want to challenge yourself besides the preset programs, you can try a treadmill with many incline levels.

There are manual and automated inclines that you can change the levels without stepping off the treadmill.

⦿ Safety Features

Treadmills don't have many reported cases of injuries, but you never know when your day will come. Safety features include hand grips and a safety key that turns the machine off immediately once unplugged.

Foldable treadmills also have mechanisms that lock the equipment, preventing it from unfolding while in transit. Keep the treadmill key away from children and never leave it plugged in the machine when not in use.


The Merax electric folding treadmill review gives a complete outlook of the most budget-friendly machines you can buy today. The editor's choice from the list is the Merax Folding Electric treadmill because of the 15 preset programs and available Bluetooth function.
