INTRODUCTION
Congratulations on the purchase of your new Diamondback Fitness computer-controlled indoor cycle. You have
made a great choice and are about to enjoy one of the most effective and technically-advanced methods of low-
impact cardio-vascular exercise available today.
Founded in 1991 as an off-shoot of the legendary bicycle company, Diamondback Fitness was in many ways a
complimentary addition to the Diamondback brand. One might even say this extension grew as a natural
evolution…an evolution from classic outdoor bicycle usage, toward indoor-based cycling and cross training. It turns
out that many fitness enthusiasts were searching for ways to maintain conditioning during times of inclement
weather or simply looking for new and different cross-training options.
This trend still continues today, twenty years later, as the strong Diamondback brand resonates with both the
boomers who grew up with the bicycles, as well as the younger generations riding them today.
Diamondback Fitness continues to build upon this legendary brand identity by offering the cardio enthusiast a full
line of upright exercise bikes, recumbent cycles, and elliptical trainers, each offering superior value and quality with
intuitive and visually-appealing design. Let’s just say, we are already planning our next twenty years.
Thank you for choosing Diamondback Fitness.

Heart Rate is an Important Key to Your Exercise
The Surgeon General also released a report on physical activity and health. This report dictates that exercise and fitness are
beneficial for a person’s health and reiterated the need for exercise as a key component for disease prevention and healthier
living.
The best way to determine exercise intensity is to monitor your pulse rate. Your heart rate can easily be determined by counting
the number of heart beats per minute at the chest, wrist or the carotid artery on your neck. It is difficult however to count your
own pulse while exercising as it is not possible to count fast enough to accurately track the number of beats per minute. This
Diamondback Fitness unit is equipped with a wireless heart rate receiver.
Using the Wireless Heart Rate Receiver
A wireless telemetry heart rate receiving system is one feature found on this unit. In order for the console to detect and display
your heart rate, four (4) conditions must be present:
A compatible heart rate chest strap transmitter (not included) must be functioning and worn. For proper function of
the chest strap, please refer to the manufacturer’s instructions. Non-coded transmitters such as the Polar model T31
and T34 are examples of wireless chest straps known to be compatible with this unit.
The unit must be powered on.
A workout program must be running.
The user is within three (3) feet of the console.
In general, a wireless heart rate chest strap is the most accurate and convenient method of detecting and monitoring a heart
rate signal and is a considerable upgrade from the touch type heart rate sensors. Occasionally, certain factors can negatively
affect the accurate transmission of the heart rate signal. WiFi networks, cordless telephones and large electrical appliances may
degrade or corrupt the signal so that the rate appears erratic or impossibly high. The only remedy for such a symptom is to
isolate the unit from potential disturbances. Additionally, a person’s body chemistry or lack of perspiration can prevent the
chest strap from providing a strong or accurate heart rate signal. Always follow the chest strap manufacturer’s instructions and
recommendations.

910Ic Owner’s Manual

Calculated Maximum Heart Rate & Target Training Zone
Your calculated target heart rate, or the ideal intensity needed to
improve cardiovascular fitness, depends primarily upon your age
rather than your current state of fitness. If the exercise intensity
is too low or too high, only modest gains will be made in strength
and cardio-vascular fitness. A workout at a very low intensity will
not offer maximum benefits. Conversely, if the workout intensity
is too high, injury or fatigue may slow the progression of your
exercise goals as the body attempts to recover.
Note: It is most effective to train at a heart rate
between 60% and 85% of your maximum heart
rate. Maximum heart rate is calculated as a
percentage of your maximum heart rate
(estimated as 220 beats-per-minute minus your
age).
To calculate your maximum heart rate and find the appropriate
target training zone, use the following formulas. For example,
the following estimation would be relevant for a 35 year-old
user:
220 –35 = 185 Bpm (220 –Age = Calculated Maximum Heart Rate in Beats-per-minute/Bpm)
0.60 x 185 = 111 Bpm (60% of 185 BPM [Calculated Maximum Heart Rate] = 111 Bpm)
0.85 x 185 = 157 Bpm (85% of 185 BPM [Calculated Maximum Heart Rate] = 157 Bpm)

18
Based on these calculations, the recommended heart rate training zone for this user would be between 111 Bpm –157 Bpm.
The graph below displays the recommended heart rate training zone for users twenty years of age to seventy-five years of age.

910Ic Owner’s Manual
19
WORKOUT QUALITY AND QUANTITY
It is recommended that you accumulate at least thirty (30) minutes of physical activity most days of the week. The American
College of Sports Medicine makes the following recommendations for the quantity and quality of training for developing and
maintaining cardio-respiratory fitness in healthy adults:
An activity that uses large muscle groups, maintained continuously, and is rhythmical and aerobic in nature.
Duration: 20 to 60 minutes of continuous aerobic activity, including a warm-up and cool-down period for each
session.
Frequency: 3 to 5 times per week.
Intensity: 60% to 85% of maximum heart rate.
In addition to aerobic exercise, strength training of moderate intensity twice per week is recommended. Women especially may
benefit from weight-bearing exercises. Select activities you enjoy and can fit into daily life. Having Diamondback Fitness
equipment at home offers you the opportunity to work out without going to the gym.
Get a Smart Start on Exercising
Anyone over the age of 35, as well as younger persons whom are overweight, should check with his/her physician before
commencing an exercise program. Persons who have diabetes or high blood pressure, a family history of heart disease, high
cholesterol or have led sedentary lifestyles should protect themselves with a medical check-up and stress test administered by a
healthcare professional.
Stretching and massaging major muscles (such as your quadriceps) following a workout session will aid in the
dissipation of lactic acid and speed your body’s recovery.
The first few minutes of your workout should be devoted to warming up the muscles before a vigorous workout.
Concentrate on raising your heart rate slowly.
After an aerobic workout of roughly 20-30 minutes, spend 10 minutes gradually reducing your heart rate by moving
slower or with less resistance.
NOTE: Start slow, with intensity low until you build up endurance and strength. Always consult your physician before
beginning any exercise program.

CONSOLE OVERVIEW & GENERAL NOTES
A primary feature of the 910Ic is the ability to control and monitor the user’s workout program
via the brilliant LCD console. At any time, the user may view their speed, RPM, elapsed time,
distance, Watts, calories and pulse rate.
To provide power to the display console and computer, begin pedaling at a rate exceeding
fifteen (15) revolutions per minute. The 910Ic Computer Controlled Indoor Cycle employs the
use of an on-board generator to supply power to the computer, console display and resistance
control system while the unit is in use. While the unit generates power for the current functions,
a set of batteries is also charged to allow console operation for up to sixty (60) seconds without
pedaling. Should the battery ever run down or if the console does not light, connect the
included power supply/adaptor to a 120V power source. Plug the opposite end into the 910Ic
power input jack found near the ground at the rear of the machine. Begin pedaling to recharge
the battery.
To avoid damage and danger, use only the power supply/adaptor that was designed for the
910Ic. To maintain and extend the life of the battery, it is necessary to charge the battery
overnight, once per week.
To conserve energy, the console will automatically power down after sixty (60) seconds of
inactivity.
CONSOLE LCD DISPLAY
Matrix Display. The Matrix Display (also called a “brickyard”) is comprised of a 128 segments arranged in
sixteen (16) horizontal columns, eight (8) rows high. The height of the lit vertical stack represents the current
resistance level. The flashing column will display the progress in the current program. Each column equals
1/16th of the total program run time.

910Ic Owner’s Manual
21
Elapsed Time. The Time display field begins to count up as soon as the program is launched. The clock will
accumulate time up to 99 minutes, 59 seconds.
Speed. Speed is displayed in miles-per-hour from 0.0 to 99.9. SPEED and RPM will alternate every four (4)
seconds as they are displayed in the same field.
RPM. RPM, or revolutions per minute, is the number of complete pedal rotations a single pedal makes in sixty
(60) seconds. The displayed range is 0 to 999. RPM and SPEED will alternate every four (4) seconds as they are
displayed in the same field.
Distance. Distance is displayed in miles and will begin to accumulate when the program is launched. The range
of the display will be from 0 minutes, 1 second to 99 minutes, 60 seconds.
Heart Rate. The pulse or heart rate will be displayed in beats per minute. The signal has to receive a heart rate
between 30 BPM and 240 BPM to register. When a heart rate is detected by the console, the heart symbol will
flash. A wireless heart rate transmitter such as the Polar un-coded T31 or T34, is required for the heart rate
monitoring function to operate.
Calories. The total calories burned since the program launch will be displayed in the Calories field. Speed,
Resistance and Time are all factors that determine the rate at which the calories are burned.
Watts. Watts is a unit of power that is often tracked during exercise routines to represent the amount of
“work” being generated. While the program is operating, the total Watts generated by the user will be
displayed. If operating a program with a Watt target control, the circle to the left of the Watt value will flash to
indicate that the user is generating a Watt value close to the preset target. The flashing arrows will indicate that the Watt value
is above or below the target.
