Our Rating

Rating: 88.5/100.  The Precor UBK 815 is sold with a home use warranty, but it’s the same machine that Precor sells to high-traffic health clubs. It is the second of three upright exercise bikes in its series. The 815 is virtually identical to the top-of-the-line 835, which costs about $600 more. The main difference between these two models is the number of preset programs. The 815 has six workout programs (versus 12 on the higher model), 25 resistance levels and three-position handlebars for upright, cruising and road positions. The seat stem is precisely angled to minimize pressure put on your knees, making this an especially low impact upright exercise bike. The Precor UBK 815 has a base price of $3,255 with a 10-year parts warranty and one-year labor warranty.
