Question: does this machine have the option to raise the incline?
Document: The Kettler Axos is a good solid machine. Unlike other ellipticals that I have tried, the Axos has no wobbles or squeaks. Using the programmed routine gives me a great workout. The spare tire is deflating!
Very well made piece of equipment! Bearings are in essential spots and it looks and works great. This machine is fairly compact and operates very smooth and quiet. I would recommend this to any who needs a compact and high quality piece of equipment.
This is a terrific piece of equipment. Built to last, it's operation is smooth and balanced. Great addition to a home gym.
This elliptical was fairly difficult to set up, most parts were easy , however a few items were more difficult. Two people at least are definitely needed for assembly. This elliptical worked great at first, but then it started squeaking. After tightening some bolts I was able to eliminate the squeaking, I am assuming I may have to do this from time to time. I am a fairly small individual, and there is a slight rocking motion when in use.
I researched and tried various brands of ellipticals and decided to purchase the Kettler Axos for home use. The operation of this elliptical is very smooth, quiet and quality is excellent. This elliptical fit my height, weight, and stride class, so choose the Kettler that's right for you. It does require some assembly and being somewhat mechanically inclined and following instructions does help.
