Bottom Line U616 Vs. U618: The Nautilus U618 upright exercise bike offers a wide array of improvements and differences over the U616 model, that may be overlooked. You get an included heart rate strap, a superior Nautilus Gel™ Seat which is oversized for comfort, bigger forearm pads, and most importantly convenient controls on the handles for resistance. In addition you get a longer frame, parts, and electronics warranty, and a heavier sturdier frame. This results in a higher user weight capacity of 325 lbs. Both models are excellent bikes, but the U618 has the edge in features.
