Ever wondered what makes a treadmill better than another? You may be surprised to learn that every single component of the treadmill adds to its own unique treadmill-character. It seems pretty obvious that the mechanical bits of the treadmill would add to its value, such as the motor, the rollers, the console and so on. It is not as obvious that belts actually differ quite a bit.
A high quality treadmill is going to come with a two-ply belt. The top layer of the belt is going to be made of polyurethane, and the under-layer is going to be made of nylon-polyester weave. The top layer is going to outlast the bottom layer easily. The wear and tear of the rollers against the inside of the belt is going to do a lot more damage than your floppy feet will.
There are three things to look for when it comes to belts.
1. Look at the cut. Is it diagonal or is it a straight cut. Diagonal seams are more durable for two reasons. They have extra bonding area and the seam gradually passes over the rollers rather than all at once.
2. Look at the weave. When dealing with any type of fabric, even if it is polyurethane, a higher thread count is always better. The tighter the weave the more durable the belt is going to be.
3. Look underneath the belt. Feel the corner to see what the underside is like. The underside should be cottony and soft, from the polyester. Listen to the sound of the treadmill in use. If it sounds like bees buzzing don’t use that treadmill. The course underside of the treadmill will cause the machine to run hot and wear out quicker.
