Nautilus

Nautilus began as a strength machine product and has since evolved into an exercise equipment company that now makes and sells upright bikes, treadmills, recumbent bikes, and ellipticals. Nautilus sells its own products as well as a variety of other brands’ products, including Bowflex, Schwinn, Universal, and Octane Fitness.

Nautilus offers a money-back guarantee if you contact its customer service department within six weeks of delivery. However, the refund does not include shipping and handling costs. Also, if you purchase Nautilus products from a retail store, the return and refund policy will vary by location.
