Overview
An auto incline treadmill with a 0 to 15 degree incline range, a 3.5 HP brushless motor, and speeds up to 8.7 mph. Built for home use with a 300+ lb weight capacity and a dual layer wide belt.
The auto incline is the notable feature here: it adjusts from the console or handlebars without stopping the belt, unlike treadmills that require manually lifting the frame. Four handlebar height settings, from 36.5 to 43.5 inches, aim to fit a range of user heights. No customer reviews are attached to this listing yet, so real world reliability is unconfirmed.
