GETTING STARTED
Note: Throughout this manual, all references to the left or right side and to the front or back are
made as if you were on the machine, ready to exercise.
Guidelines for Getting On and Off the Bike
Instruct each user in the following guidelines for getting on and off the bike.
Adjustments
You should check two adjustments before using the Nautilus® U916 or R916 bike: the seat and the pedal foot strap
length.
Seat Height Adjustment on the U916 Upright Bike
Sit on the seat. Put both feet onto the pedals and into the foot straps. Pedal slowly and then stop when one leg is
extended and your foot is as close to the floor as possible. The knee of the extended leg should be slightly bent
when the sole of your foot is parallel to the floor. If you need to adjust the seat higher, get off the bike and stand to
one side. Pull up on the saddle (it’s not necessary to release the seat adjustment handle to adjust the seat higher).
The seat adjustment mechanism will automatically lock into place once you have reached your desired seat
height. To lower the seat, pull up on the seat adjustment handle (located under the front of the saddle) to release
the locking mechanism, and then gently lower the saddle to your desired seat height. Release the seat adjustment
handle and the seat will automatically lock into place. Lower or raise the seat as necessary.
It is also possible to adjust the seat without getting off the bike. Simply take your weight off the saddle while in the
pedals, and raise or lower the saddle as described above.
TO AVOID INJURY, PLEASE CAREFULLY
FOLLOW THE INSTRUCTIONS.
DO NOT ADJUST THE SEAT HEIGHT
WITH YOUR WEIGHT ON THE SADDLE.
Seat Adjustment on the R916 Recumbent Bike
Sit on the seat. Put both feet onto the pedals and into the foot straps. Pedal slowly and then stop when one leg is
extended. The knee of the extended leg should be slightly bent. The seat adjustment lever is located in front of the
seat base. Remain seated and keep your feet on the pedals. Pull up on the lever and slide forward or backward as
necessary. Push the lever down completely to lock into place. Make sure the seat is locked in place by trying to
move the seat forward and backward before you start pedaling.
Foot strap Adjustment
To ensure your feet are properly secured to the pedals, you need to check the position of the foot straps. Position
your foot so that the ball of your foot is over the pedal spindle. The pedal foot straps should be tight enough to
Nautilus® Commercial Series Bike Owner’s Manual

GETTING STARTED
secure your feet to the pedals but not so tight so as to cut off the circulation.
There is a ratcheting strap and buckle system on the outside of the foot strap
and two adjustment holes on the inside foot strap mount. To tighten the strap,
pull the end of the strap through the self-locking buckle as needed. To loosen
the strap, push down on the buckle mechanism to release the lock, and adjust
as necessary. If you cannot reach the adjustment straps while seated on the
bike, get off the bike and stand to one side. If you need to make additional
adjustments, carefully grasp the pedal with one hand and pull the outside end
of the foot strap off the inside adjustment tab with your other hand. Insert the
adjustment tab through the proper hole on the foot strap.
1. Position yourself comfortably on the bike and begin pedaling. You should see the “SELECT WORKOUT” message on
the display.
2. Select the MANUAL exercise program so you can control the pace of
your first workout and get used to the exercise motion. Press [MANUAL]
and then press [ENTER].

“ENJOY WORKOUT” and your program will begin. If you do not start
exercising within 30 seconds, the console will return to the start screen.

Understanding the Display and Controls
The machine’s console is a computerized panel used to operate your exercise bike and to
display all workout data. Take time to read through the following sections so that you can
properly understand its operation and take full advantage of all of your machine’s workout
options.
Display Definitions and Functions
The following describes the display functions on the Commercial Series R916 and U916 bikes.
Time—The selected workout time is displayed in the upper left section of the upper display
window. In most of the workouts, the timer will count down, in minutes and seconds, until
the workout is finished or stopped. If (0) is entered in the (MANUAL) or (HR ZONE TRAINER)
workout, the timer will count up.
Interval Timer—The interval timer is displayed in the lower display, upper left corner. The
interval timer counts down the remaining time within each interval.
Resistance Level—Displays the current intensity level between 1 (the easiest) and 20 (the
hardest). Pressing the

DISPLAY AND CONTROLS
Heart Rate—Current heart rate, in beats per minute, is displayed next to the
heart icon on the lower display.
Percentage of Maximum Heart Rate—An approximation of maximal heart
rate is calculated based on the latest American College of Sports Medicine
User should consult a physician to
determine an appropriate target
heart rate in which to exercise in
based on age, weight and physical
condition. While Nautilus provides
some target heart rate ranges,
these are only approximations and
should not be viewed as a medical
recommendation.
predictive equation as follows:
Max Heart Rate = 215 – (Age * .75)
Percentage of maximum heart rate will only be shown in HRC programs.
Example: For a person 40 years of age, max HR is estimated
as (215 – (40 (age) * .75) = 185 .
185 beats per minute would be the approximate maximum heart rate for a 40year-old user.
185 = 76%) will be displayed in the upper left corner of the lower display area.
This means that the 40-year-old user working at 140 beats per minute is at 76%
of their maximum heart rate.
If the user works out at 140 beats per minute, then 76% (140 /
(See the Heart Training programs for more information.)
Distance—Provides a cumulative total of the equivalent distance, in miles (or
kilometers if your display is set to metric units), you have traveled.
Calories— Provides a current total of the number of Calories burned during
a workout. Note: this number is only an approximation as a user’s caloric
expenditure will vary significantly based on a person’s age, gender, weight and
metabolism.
Calories/Hour— Provides the rate at which calories are burned per hour at the
current resistance level and RPM.
Speed— Displays the speed in in miles per hour (or kilometers per hour).
RPM— Displays the pedal revolutions per minute.
Watts—During a workout, this statistic displays the power output at the
current RPM and intensity Level, displayed in watts (746 watts = 1 hp).
METs—Gives you the relative energy cost of exercise. MET stands for
multiple of the resting metabolic rate. While you are sitting quietly, your body
consumes oxygen at the rate of 1 MET or about 3.5 milliliters per kilogram of
body mass per minute. When you exercise, your body needs more oxygen in
order to function. For example, exercising at 10 METs requires ten times the
resting rate of oxygen consumption, or about 35 milliliters per kilogram per
minute. During a workout, the display shows the current MET level. During
the workout summary, the average MET level is displayed. During your

workout, keeping track of the METs will show you how hard you are working—the higher the MET level,
the harder you are working.
Workout Profile—The dot-matrix area of the display shows the actual course profile of the selected
exercise program. The taller the column, the higher the resistance level and/or METs for that interval.
The flashing column shows your current interval.
