The U618 Upright Exercise Bike is the newest and higher-end bike in the Nautilus range and is constructed to withstand high intensity workouts making it suitable for the more serious athlete.
The Nautilus U616 sits in the middle of the range and is ideal for moderate exercise, while the U614 is Nautilus’ entry-level bike that’s ideal for beginners.
The consoles on all 3 Nautilus upright bikes are fairly straightforward to use, but the overall design of the consoles varies between the 3 bikes, with the U618 and U616 having blue backlit display screens which is easier to view than the U614’s black/grey screens. The STN display on the U618 is the best in the fitness industry, making it easier on the eyes.
Motivating workout stats displayed on all bikes include time, speed, distance, calories and heart rate. The Nautilus U618 and U616 bikes have the advantage of offering both contact grip and telemetry enabled heart-rate monitoring whereas the U614 only offers pulse contact grip monitoring.
The Nautilus U618 and U616 upright bikes also have the added advantage of a 4-way adjustable seat (up, down, fore, aft) to give a more custom fit compared to the U614’s seat which is height adjustable only.
The Nautilus U618, U616 and U614 exercise bikes all include some great additional features such as 3-speed cooling fan, sound system with speakers and MP3 input, media shelf and water bottle holder (dual water bottle holder on the U618).
