The ability to store a treadmill under the bed is a benefit for people who want to exercise but have limited space or don't like to leave their exercise equipment within sight. Because the average under-bed space is about 14 inches, some portable, compact treadmills can be folded and rolled under the bed to clear floor area in the rest of the room.
The Evolve by Horizon is an ultra-compact treadmill that folds down to a mere 10 inches high and 59 inches long but offers a large 17 by 45 inches workout space when unfolded. You can choose from two programs -- manual and weight loss -- as the 1.25 CHP motor allows you to walk or jog at speeds up to 6 mph on the 1.6 mm ComfortZone belt. Horizon offers 10-year frame, five-year motor and one-year parts and labor warranties. The Evolve is suitable for users up to 250 pounds. In 2011, it retailed for about $800.
This compact treadmill folds down to just 11 inches for easy under-bed or closet storage. This light-use treadmill can incline up to 6 percent and supports users up to 250 pounds. The LCD console tracks your time, distance, calories, speed and incline and has built-in console speakers, allowing you to listen to your iPod or MP3 player as you walk or jog at speeds up to 8 mph. The TR200i also features a USB port which allows you to upload to your LifeSpan Fitness online account, giving you access to exercise programs and detailed reports of your exercise and health results. It comes with a lifetime warranty on the frame as well as warranties for the motor, parts and labor. In 2011, the TR200i retailed for about $800.
Ideal for light use, the TR100 by LifeSpan features many of the same benefits as the TR200 but costs about $100 less in 2011. Its ability to fold to a compact 11 inches makes it easy to store under a bed or in a closet. Like the TR200i, the 1.5 HP continuous duty motor allows you to walk or jog at speeds up to 8 mph on the 17-inch wide, 48-inch long workout space. The TR100 does not offer a USB port but does have speakers, a headphone plug-in and heart rate sensors in the hand grips.
While being able to store your treadmill under the bed can be a major benefit, many units sacrifice sturdy construction for portability. Most folding treadmills are not built to withstand heavier use or use by individuals over about 250 pounds. If you plan to use a treadmill for running at speeds over 8 mph, a compact treadmill may not be durable enough for you.
