The Smooth 6.45 is the new treadmill to replace Smooth’s iconic 6.25 model. Although this model is newer, and therefore considered to have numerous flaws, Smooth has eliminated most possible flaws by basing this new treadmill on the 6.25 platform, and includes a modified frame, and many of the same electronics as the 6.25. As a result the 6.45 does not have the usual flaws associated with most new treadmill models.

One of the most noticeable improvements in the 6.45 model over the 6.25 model is the treadmill belt. The belt on the 6.45 is 60” compared to the 6.25 model’s 54” belt. What this means is that taller users and runners will have an easier time running on this treadmill without feeling like falling off the end of the machine.

Another great feature with the 6.45 is Smooth’s shock absorption system. This shock system absorbs a significant amount of stress which would normally be put on your ankles, knees, hips, and your back. Also, unlike other shock absorption systems, this newer system doesn’t give the bounce at the back of the treadmill that is experienced in many other treadmills. Instead the 6.45 is designed for the rear to be tighter than the front, giving the user a firm push off for their stride without the bounce associated with other brands.

With this treadmill’s great price, many improvements, and great 1 year service, and 5 year parts warranty I give the Smooth 6.45 3.5 out of 5 Golden Buddahs.
