How long will the Xterra TR6.6 last?

The Xterra TR6.6 treadmill is a higher end offering in the Xterra Sports series and offers quite a formidable warranty which is substantial with its lifetime frame and motor warranty and 5-year deck warranty. The treadmill weighs in at a decent 260 lbs. and can hold up to 350 lbs. max capacity and while the parts warranty is only 2-years, it still offers a lot of benefits for beginning to moderate users. With a regular maintenance schedule, fitness followers will get a few years of steady use from this foldable machine.

Brief Overview

The Xterra TR6.6 holds its ground well with other competitors in the less than $1300 price range with many benefits for beginners to moderate users alike. While not best in class technology-wise, the generous warranty and high-performing parts make this treadmill a decent purchase if entertainment is not high on your list of needed workout features.

Overall Quality

The Xterra TR6.6 treadmill is a sturdy, reliable model that provides a comfortable workout for different size family members. It has a 3.0 HP motor that can go up to 12 mph and incline up to 15 levels with the electronic controls found comfortably in the handlebars. This affordable treadmill has a running space that is 20" wide by 60" long, large enough for moderate users to get the workout they are looking for with less impact on their joints due to the cushioning built into the deck. The Xterra TR6.6 treadmill features 12 built in programs that will keep users engaged and challenged when they exercise if they are not use to more entertainment options and a larger than 7.5” screen. This model also comes with a built-in cooling fan, an accessory tray, and a cup holder so your workout is more comfortable. It has a folding frame that makes it easy to store in a smaller space when it is not needed. Its design also includes lift assist so the machine can be folded safely by one person with minimal effort. It basically offers every functioning detail a treadmill enthusiast will need to start or continue their fitness journey.

The Xterra TR6.6 performance specs and included features of this treadmill make it a great buy for beginning to moderate users. It comes with powerful motor and a spacious running surface—some would say the most important features in any worth-while machine. It also has heavy duty frame plus high weight capacity which means you can depend on your purchase lasting years down the line, especially since their warranty on frames and motors is incredibly lavish. For the asking price, this treadmill offers enough functional features to make it a competitive offering for those not interested in focusing on entertainment while they workout.
