It allows you to travel the world virtually while you are training.
The Nautilus U614 and Nautilus U616 are both built with magnetic resistance systems and can accommodate users up to 300 lbs.

With 25 levels of resistance, wireless heart rate monitor capability (not included), and a 22 lbs. flywheel, the U616 offers some serious improvements over the U614 model (20 resistance levels, only contact-type heart rate monitor, 18 lbs. flywheel).
