Nautilus T616 vs Nautilus T618 Features Overview
In this head-to-head comparison, we match the T616 and T618 from Nautilus. They are very similar treadmills in terms of frame design, but what about the features?
The Nautilus T618 is a stronger treadmill when it comes to motor power and maximum weight capacity. The Nautilus T616 has a 3.0 CHP motor and 300 lbs weight capacity, while the T618 gives you a bit more power with its stronger 3.5 CHP motor. It also has a higher weight capacity, 350 lbs.
Both treadmills have a 20″ X 60″ treadmill track size but the T618 has a better belt. It has a 3-ply, 2.5 mm thickness belt. The T616 has a 2-ply, 2.0 mm thickness belt.
The last advantage worth talking about is the handrail controls. The T618 has handrail controls for incline and speed for quickly adjusting your training intensity. The T616 does not have handrail controls, so you have to use the buttons on the console to change your speed or incline level.
Here we list both vacuum treadmills’ main features before getting into our more detailed side-by-side comparison.
