Important Safety Instructions
WARNING - Read all instructions before using this appliance.
If using the optional power supply:
DANGER - To reduce the risk of electric shock disconnect your Spirit Fitness fitness bike from
the electrical outlet prior to cleaning and/or service work.
WARNING - To reduce the risk of burns, fire, electric shock, or injury to persons, install
the fitness bike on a flat level surface with access to a 110-volt, 15-amp grounded outlet with
only the fitness bike plugged into the circuit.
ƒƒ Do not operate fitness bike on deeply padded, plush or shag carpet. Damage to both carpet
and fitness bike may result.
ƒƒ Keep children away from the fitness bike. There are obvious pinch points and other
caution areas that can cause harm.
ƒƒ Keep hands away from all moving parts.
ƒƒ Never operate the fitness bike if it has a damaged cord or plug. If the fitness bike is not
working properly, call your dealer.
ƒƒ Keep the cord away from heated surfaces.
ƒƒ Do not operate where aerosol spray products are being used or where oxygen is
being administered. Sparks from the motor may ignite a highly gaseous environment.
ƒƒ Never drop or insert any object into any openings.
ƒƒ Do not use outdoors.
ƒƒ To disconnect, turn all controls to the off position, then remove the plug from
the outlet.
ƒƒ Do not attempt to use your fitness bike for any purpose other than for the purpose it is
ƒƒ The hand pulse sensors are not medical devices. Their purpose is to provide you with an
approximate measurement in relation to your target heart rate. Use of a chest transmitter
strap (sold separately) is a much more accurate method of heart rate analysis . Various
factors, including the user’s movement, may affect the accuracy of heart rate readings. The
pulse sensors are intended only as exercise aids in
determining heart rate trends in general.
ƒƒ Wear proper shoes. High heels, dress shoes, sandals or bare feet are not suitable for use on
your fitness bike. Quality athletic shoes are recommended to avoid leg fatigue.
XBU55 Fitness Bike
NEVER remove any cover without first disconnecting AC power. If voltage varies by ten
percent (10%) or more, the performance of your fitness bike may be affected. Such
conditions are not covered under your warranty. If you suspect the voltage is low, contact your
local power company or a licensed electrician for proper testing.
NEVER expose this fitness bike to rain or moisture. This product is NOT designed for use
outdoors, near a pool or spa, or in any other high humidity environment. The operating
temperature specification is 40 to 120 degrees Fahrenheit, and humidity is 95% non-condensing
(no water drops forming on surfaces).
Imporant Operation Instructions
ƒƒ NEVER operate this fitness bike without reading and completely understanding the results
of any operational change you request from the computer.
ƒƒ Understand that changes in resistance do not occur immediately. Set your desired resistance
level on the computer console and release the adjustment key. The computer will obey the
command gradually.
ƒƒ NEVER use your fitness bike during an electrical storm. Surges may occur in your household power supply that could damage fitness bike components. Unplug the fitness bike during
an electrical storm as a precaution.
ƒƒ Use caution while participating in other activities while pedaling on your fitness bike; such as
watching television, reading, etc. These distractions may cause you to lose balance which may
result in serious injury.
ƒƒ Do not use excessive pressure on console control keys. They are precision set to function
properly with little finger pressure.

Product Features
The fitness bike is equipped with two transport wheels that are engaged when the rear of the
fitness bike is lifted.
Seat Adjustability
When adjusting the seat to a higher position, just pull up on the seat. The design features a
ratcheting mechanism that will lock into place. If you need to lower the seat, pull horizontally on
the on the right side of the frame until the post locks into one of the grooves.
The console will display RPM, Calories burned, Time (elapsed or countdown), Distance travelled,
Pulse, Resistance Level, Program Name, Speed, Watts, and number of Laps completed. There is
also a resistance level profile graph that lets you see how hard you have worked and how challenging the upcoming segments will be.
XBU55 Fitness Bike
There is an anatomical figure located at the top of the console. This figure will light all areas that
are activated when using the bike. These will light up during any of the programs. You can control
which muscles are activated by customizing the resistance profile during the set up phase of console programming. If you accept the default program profile, the selected program will determine
which muscles will be activated by automatically adjusting the resistance. Generally the following
guidelines hold true:
The upper body LED’s will not light
The lower body lights will activate in three degrees of engagement: Green
represents minimal muscle involvement, yellow represents medium involvement, and red represents full or heavy activation.
These are the different scenarios for lower body muscle activation:
• Levels 1-10: Green – Hamstrings & Gluteals light up; Yellow –
Quadriceps & Calves light up
• Levels 11-20: Yellow – Hamstrings & Gluteals light up; Red –
Quadriceps & Calves light up
The console LCD screen will display your current heart rate anytime a
pulse is detected. The Bar Graph, located to the right of the LCD screen,
will show your current heart rate % in relation to your projected maximum
heart rate, which is determined by your age that you entered during the
programming phase of any of the 10 programs. The significance of the bar
graph colors are as follows:
50-60% of maximum is Amber
65-80% of maximum is Amber and Green
85-90% or more is Amber, Green, and Red

When the A.C. Power cord is connected to the fitness bike, the console will automatically power
up. If there is no input to the console for 20 minutes the console will go to stand-by mode. In
stand-by mode the console display will turn off. To turn the console on press any key.
When initially powered on the console will perform an internal self-test. During this time all the
lights will turn on. When the lights go off, the Message Center will show the software version (i.e.:
VER 1.0). The distance window shows the distance in miles and the time window shows the total
hours of use.The dot matrix display will be scrolling through the different profiles of the
programs and the message window will be scrolling the start up message. You may now
begin to use the console.
XBU55 Fitness Bike
Dot Matrix Center Display
Twenty columns of boxes (8 high) indicate each segment of a workout. The boxes only show an
approximate level (resistance) of effort. They do not necessarily indicate a specific value - only an
approximate percent to compare levels of intensity. In Manual Operation the resistance dot matrix window will build a profile “picture” as values are changed during a workout.
The resistance profiles will display half of the program at one time (9 columns). They will both scroll right
to left. The Lap track will move in a counterclockwise direction.
1/4 Mile Track
The 1/4-mile track (one lap) will be displayed around the dot matrix window. The flashing
segment indicates your progress. Once the 1/4-mile (Metric - 0.4k) is complete this feature will
begin again. There is a lap counter in the message window for monitoring your distance.
Pulse Grip Feature
The Pulse (Heart Rate) console window will display your current heart rate in beats per minute
during the workout. You must use both stainless steel sensors on the front cross bar or the heart
rate transmitter chest strap to display your pulse. Pulse value displays anytime the upper display is
receiving a Pulse signal. You may not use the Grip Pulse feature while in Heart Rate Programs.
Note: Refer to Important Safety Instructions (page 2) concerning Pulse Grip operation.
Calorie Display
Displays the cumulative calories burned at any given time during your workout.
Note:This is only a rough guide used for comparison of different exercise sessions, which cannot be used for
medical purposes.
The console has built-in Speakers. You may plug an Audio Source (CD player, MP3, Computer,
etc.) into the Jack on the right side of console. There is no volume control on the console. The
volume must be controlled on the Audio Source.
XBU55 Fitness Bike
Quick Start
This is the quickest way to start a workout. After the console powers
up you just press the Start key to begin, this will initiate the Quick
Start mode. In Quick Start the Time will count up from zero and the
workload may be adjusted manually by pressing the Level Up/
Down buttons. The dot matrix display will have only the bottom row
lit at first. As you increase the work load more rows will light indicating
a harder workout. The fitness bike will get harder to pedal as the rows increase.
There are 20 levels of resistance available for plenty of variety. The first 5 levels are very easy
workloads and the changes between levels are set to a good progression for de-conditioned
users. Levels 6-10 are more challenging, but the increases in resistance from one level to the
next remain small. Levels 11-15 start getting tough as the levels jump more dramatically. Levels
16-20 are extremely hard and are good for short interval peaks and elite athletic training.
Basic Information
The Message Center will initially be displaying the Program name.
When in scan mode during a program, speed will be displayed for four
seconds, then move on and display Watts (indication of workload). If
100 watts is displayed, you are doing enough work to keep a 100-watt
light bulb lit. The data changes to Laps completed, Segment time, Max
level. Pressing the Enter button again will bring you back to
the beginning.
The Stop button actually has several functions. Pressing the Stop key
once during a program will pause the program for 5 minutes. If you
need to get a drink, answer the phone or any of the many things that
could interrupt your workout, this is a great feature. To resume your
workout during Pause, just press the Start key. If the Stop button is
pressed twice during a workout, the program will end and the console will display your
Workout Summary (Total time, Avg. Speed, Avg. Watts, Avg. HR, total Laps). If the Stop key is
held down for 3 seconds or a third time during the program, the console will perform a
complete Reset. During data entry for a program the Stop key performs a previous
screen or segment function. This allows you to go back to change programming data.
XBU55 Fitness Bike
Program Keys
The program keys are used to preview each program. When you first turn the console on you
may press each program key to preview what the program profile looks like. If you decide that
you want to try a program, press the corresponding program key and then press the Enter key
to select the program and enter into the data-setting mode.
The fitness bike has a built in heart rate monitoring system. Simply grasping the hand pulse sensors on the stationary handle bars or wearing the heart rate transmitter (see Using Heart Rate
Transmitter section) will start the Heart Icon blinking (this may take a few seconds). The Pulse
Display Window will display your heart rate, or Pulse in beats per minute.
The console includes a built-in fan to help keep you cool. To turn the fan on, press the button on
the left side of the console.
Programming The Console
Each of the programs can be customized with your personal information and changed to suit
your needs. Some of the information asked for is necessary to ensure the readouts are correct.
You will be asked for your Age and Weight. Entering your Age is necessary during the Heart
Rate programs to ensure the correct settings are in the program for your Age. Otherwise the
work settings could be too high or low for you. Entering your Weight aides in calculating a more
correct Calorie reading. Although we cannot provide an exact calorie count, we do want to be
as close as possible.
CALORIE NOTE: Calorie readings on every piece of exercise equipment, whether it is in a gym
or at home, are not accurate and tend to vary widely. They are meant only as a guide to monitor
your progress from workout to workout. The only way to measure your calorie burn accurately
is in a clinical setting connected to a host of machines. This is because every person is different
and burns calories at a different rate. Some good news is that you will continue to burn calories
at an accelerated rate for at least an hour after you have finished exercising!
Entering A Program And Changing Settings
When you enter a program, by pressing a program key, then Enter key, you have the option of
entering your own personal settings. If you want to workout without entering new settings, then
just press the Start key. This will bypass the programming of data and take you directly to the
start of your workout. If you want to change the personal settings then just follow the
instructions in the Message Center. If you start a program without changing the settings,
the default or saved settings will be used.
NOTE: Age and Weight default settings will change when you enter a new number. So the last
Age and Weight entered will be saved as the new default settings. If you enter your Age and
Weight the first time you use the fitness bike, you will not have to enter it every time you work
out unless either your Age or Weight changes, or someone else enters a different Age and
XBU55 Fitness Bike
Programmable Features
The Manual program works as the name implies, manually. This means that you control the
workload and not the computer. To start the Manual program, follow the instructions below or
just press the Manual button, then the Enter key and follow the directions in the
Message Center.
1. Press the Manual key, then press the Enter key.
2. The Message Center will ask you to enter your Age. You may

key to accept the new value and proceed on to the next screen.
3. You are now asked to enter your Weight. You may adjust the Weight
value using the Up/Down keys, then press Enter to continue.
4. Next is Time. You may adjust the Time and press Enter to
5. Now you are finished editing the settings and can begin your
workout by pressing the Start key. You can also go back and modify
your settings by pressing the Stop key. NOTE: At any time during the
editing of Data you can press the Stop key to go back
one level, or screen.
6. Once the program starts you will be at level one. This is the
easiest level and it is a good idea to stay at level one for a while
to warm up. If you want to increase the work load at any time press
the Up key; the Down key will decrease the work-load.
7. During the Manual program you will be able to scroll through the
data in the Message Center by pressing the Enter key.
8. When the program ends you may press Start to begin the same
program again or Stop to exit the program or you can save the
program you just completed as a custom user program by pressing a User key and
following the instructions in the Message Center.
XBU55 Fitness Bike
Preset Programs
The fitness bike has five different programs that have been designed for a variety of workouts.
These five programs have factory preset work level profiles for achieving different goals.
Resistance: This program follows a triangle or pyramid type of gradual progression from approximately 10% of maximum effort (the level that you chose before starting this program) up to a maximum effort which lasts for 10% of
the total workout time, then a gradual regression of resistance back to approximately 10% of maximum effort
Resistance: This program follows a quick progression up to the maximum resistance level (default or user input level)
that is sustained for 2/3 of the workout. This program will challenge your ability to sustain your energy output for an
extended period of time.
Resistance: This program presents a quick progression up to near maximum resistance level (default or user input
level). It has slight fluctuations up and down to allow your heart rate to elevate, and then recover repeatedly, before
beginning a quick cool down. This will build up your heart muscle and increase blood flow and lung capacity
XBU55 Fitness Bike
Resistance: This program has a gradual progression of resistance up to 100% of maximum effort that is sustained for
25% of workout duration. This will help build strength and muscular endurance in the lower body and gluts. A brief
cool down follows.
Resistance: This program takes you through high levels of intensity followed by recovery periods of low intensity.
This program utilizes and develops your “Fast Twitch” muscle fibers which are used when performing tasks that are
intense and short in duration. These deplete your oxygen level and spike your heart rate, followed by periods of
recovery and heart rate drop to replenish oxygen. Your cardiovascular system gets programmed to use oxygen more
XBU55 Fitness Bike
Programming Preset Programs
1. Select the desired program button then press the Enter key.
2. The Message Center will ask you to enter your Age. You may adjust
the age setting, using the Level Up/Down keys, then press the
Enter key to accept the new number and proceed on to the next
3. You are now asked to enter your Weight. You may adjust the Weight
value using the Level Up/Down keys, then press Enter to
4. Next is Time. You may adjust the time and press Enter to continue.
5. Now you are asked to adjust the Max Resistance Level. This is the
peak exertion level you will experience during the program. Adjust
the level and then press Enter.
6. Now you are finished editing the settings and can begin your
workout by pressing the Start key. You can also go back and modify
your settings by pressing the Enter key.
7. If you want to increase or decrease the resistance at any time
during the program, press the Level Up/Down keys on the
console or above the heart rate sensor grips of the stationary
handlebars. This will change the resistance settings of the entire
profile, although the profile picture on the screen will not change.
The reason for this is so that you can see the entire profile at all
times. If the profile picture is changed, it also would be
distorted and not a true representation of the actual profile. When
you make a change to the resistance, the Message Center will show
the current column and program maximum levels of work.
8. During the program you will be able to scroll through the data in
the message window by pressing the Enter key.
9. When the program ends the Message Center will show a summary of your workout. The
summary will be displayed for a short time, then the console will return to the start-up
XBU55 Fitness Bike
Custom User Defined Programs
There are two customizable User programs that allow you to build and save your own workout.
The two programs, User 1 and User 2, operate exactly the same way so there is no reason
to describe them separately. You can build your own custom program by following the
instructions below or you can save any other preset program you complete as a custom
program. Both programs allow you to further personalize it by adding your name.
1. Press the User 1 or User 2 key. The Message Center will show a welcome message. If you
had previously saved a program the message will contain your name. Then press the Enter
key to begin programming.
2. When you press Enter, the Message Center will show “Name - A”, if there is no name
saved. If the name “David” had been previously saved the Message Center will show “Name David” and the D will be blinking. If there is a name saved you can change it or you may press
the Stop key to keep the name and continue to the next step. If you want to enter a name
use the Up/Down key to change the first letter then press Enter to save the first letter
and continue to the next letter. When you have finished entering the name press the Stop
key to save the name and continue to the next step.
3. The Message Center will ask you to enter your Age. You may enter your age, using the Level
Up/Down keys, then press the Enter key to accept the new value and proceed on to the
next screen.
4. You are now asked to enter your Weight. You may adjust the weight value using the Up/
Down keys or the numeric key pad, then press Enter to continue.
5. Next is Time. You may adjust the time and press Enter to continue.
6. Now you are asked to adjust the Max Resistance Level of the program, press Enter when
resistance has been selected.
7. Now the first column will be blinking and you are asked to adjust the resistance level for the
first segment(SEGMENT > 1) of the workout by using the Level Up key. When you finish
adjusting the first segment, or if you don’t want to change, then press Enter to continue to
the next segment.
8. The next segment will show the same workload resistance level as the previously adjusted
segment. Repeat the same process as the last segment then press Enter. Continue this
process until all twenty segments have been set.
9. The Message Center will then tell you to press Enter to save the program. After saving the
program the Message Center says “New program saved” then will give you the option to
start or modify the program. Pressing Stop will exit to the start up screen.

Heart Rate Programs
The old motto, “no pain, no gain”, is a myth that has been overpowered by the benefits of
exercising comfortably. A great deal of this success has been promoted by the use of heart rate monitors.
With the proper use of a heart rate monitor, many people find that their usual choice of exercise intensity
was either too high or too low and exercise is much more enjoyable by
maintaining their heart rate in the desired benefit range.
To determine the benefit range in which you wish to train, you must first determine your
Maximum Heart Rate. This can be accomplished by using the following formula: 220 minus your age. This
will give you the Maximum Heart Rate (MHR)for someone of your age. To determine the effective heart
rate range for specific goals you simply calculate a percentage of your MHR. Your Heart rate training zone
is 50% to 90% of your maximum heart rate. 60% of your MHR is the zone that burns fat while 80% is for
strengthening the cardio vascular system. This 60% to 80% is the zone to stay in for maximum benefit.
For someone who is 40 years old their
target heart rate zone is calculated:
220 – 40 = 180 (maximum heart rate)
180 x .6 = 108 beats per minute
(60% of maximum)
180 X .8 = 144 beats per minute
(80% of maximum)
So for a 40 year old the training zone would be 108
to 144 beats per minute.
If you enter your age during programming the
console will perform this calculation
automatically. Entering your age is used for the
Heart Rate programs. After calculating your MHR
you can decide upon which goal you would like to pursue.
The two most popular reasons for, or goals, of exercise are cardiovascular fitness (training for the
heart and lungs) and weight control. The black columns on the chart above represent the MHR for a
person whose age is listed at the bottom of each column. The training heart rate, for either cardiovascular
fitness or weight loss, is represented by two different lines that cut diagonally through the chart. A definition of the lines’ goal is in the bottom left-hand corner of the chart. If your goal is cardiovascular fitness or
if it is weight loss, it can be achieved by training at 80% or 60%, respectively, of your MHR on a schedule
approved by your physician. Consult your
physician before participating in any exercise program.
With all Spirit Fitness Heart Rate programs fitness bikes you may use the heart rate monitor feature without using the Heart Rate program. This function can be used during manual mode or during any of the
nine different programs. The Heart Rate program automatically controls
resistance at the pedals.
XBU55 Fitness Bike
Rate of Perceived Exertion
Heart rate is important but listening to your body also has a lot of advantages. There are more
variables involved in how hard you should workout than just heart rate. Your stress level, physical
health, emotional health, temperature, humidity, the time of day, the last time you ate and what
you ate, all contribute to the intensity at which you should workout. If you listen to your body, it
will tell you all of these things.
The rate of perceived exertion (RPE), also know as the Borg scale, was developed by Swedish
physiologist G.A.V. Borg. This scale rates exercise intensity from 6 to 20 depending upon how you
feel or the perception of your effort.
The scale is as follows:
Rating Perception of Effort
6 Minimal
7 Very,very light
8 Very,very light +
9 Very light
10 Very light +
11 Fairly light
12 Comfortable
13 Somewhat hard
14 Somewhat hard +
15 Hard
16 Hard +
17 Very hard
18 Very hard +
19 Very,very hard
20 Maximal
You can get an approximate heart rate level for each rating by simply adding a zero to each rating. For example a rating of 12 will result in an approximate heart rate of 120 beats per minute.
Your RPE will vary depending up the factors discussed earlier. That is the major benefit of this
type of training. If your body is strong and rested, you will feel strong and your pace will feel
easier. When your body is in this condition, you are able to train harder and the RPE will support
this. If you are feeling tired and sluggish, it is because your body needs a break. In this condition,
your pace will feel harder. Again, this will show up in your RPE and you will train at the proper
level for that day.

2. Adjust the strap as tightly as possible as long as the strap is not too tight to
remain comfortable.
3. Position the transmitter with the logo centered in the middle of your torso facing
away from your chest (some people must position the
transmitter slightly left of center). Attach the final end of the elastic strap by
inserting the round end and, using the locking parts, secure the transmitter and
strap around your chest.
4. Position the transmitter directly below the pectoral muscles.
5. Sweat is the best conductor to measure very minute heart beat electrical signals.
However, plain water can also be used to pre-wet the electrodes (2 ribbed oval areas on the reverse side of
the belt and both sides of the transmitter). It’s also recommended that you wear the
transmitter strap a few minutes before your work out. Some users, because of body chemistry, have a more
difficult time in achieving a strong, steady signal at the beginning. After “warming up”, this problem lessens. As
noted, wearing clothing over the transmitter/strap doesn’t affect performance.
6. Your workout must be within range - distance between transmitter/receiver – to achieve a strong steady
signal. The length of range may vary somewhat but generally stay close enough to the
console to maintain good, strong, reliable readings. Wearing the transmitter directly on bare skin
assures you of proper operation. If you wish, you may wear the transmitter over a shirt. To do so, wet the
areas of the shirt that the electrodes will rest upon.
Note: The transmitter is automatically activated when it detects activity from the user’s heart. Additionally, it
automatically deactivates when it does not receive any activity. Although the transmitter is water resistant,
moisture can have the effect of creating false signals, so you should take precautions to completely dry the
transmitter after use to prolong battery life (estimated transmitter battery life is 2500 hours). The replacement
battery is Panasonic CR2032.
Erratic Operation
Caution! Do not use this fitness bike for Heart Rate programs unless a steady, solid Actual Heart
Rate value is being displayed. High, wild, random numbers being displayed
indicate a problem.
Areas to look for interference which may cause erratic heart rate:
Microwave ovens, TV’s, small appliances, etc.
Fluorescent lights.
Some household security systems.
Perimeter fence for a pet.
Some people have problems with the transmitter picking up a signal from their skin. If you have problems try
wearing the transmitter upside down. Normally the transmitter will be oriented so the Spirit Fitness logo is
right side up.
6. The antenna that picks up your heart rate is very sensitive. If there is an outside noise source,
turning the whole machine 90 degrees may de-tune the interference.
7. Another Individual wearing a transmitter within 3’ of your machine’s console.
If you continue to experience problems contact your dealer.

Heart Rate Program Operation
Note:You must wear the heart rate transmitter strap for these programs
Both programs operate the same, the only difference is that HR1 is set to 60% and HR2 is set
to 80% of the maximum heart rate. They both are programmed the same way.
To start an HR program follow the instructions below or just select the HR1 or HR2
program, then the Enter button and follow the directions in the Message Center.

then press Enter. Note:The heart rate that appears is based on the % you accepted in Step 1. If you
change this number it will either increase or decrease the % from Step 1.
6. Now you are finished editing the settings and can begin your workout by pressing the
Start key. You can also go back and modify your settings by pressing the Enter key.
Note: At any time during the editing of Data you can press the Enter key to go back one screen.

Message Center by pressing the Enter key.

General Maintenance
1. Wipe down all areas in the sweat path with a damp cloth after each workout.
2. If a squeak, thump, clicking or rough feeling develops the main cause is most likely one of two
I. The hardware was not sufficiently tightened during assembly. All bolts that were installed
during assembly need to be tightened as much as possible. It may be necessary to use a larger wrench
than the one provided if you cannot tighten the bolts sufficiently. I cannot stress this point enough; 90% of
calls to the service department for noise issues can be traced to loose hardware.
II. The crank arm nut needs to be retightened
III. If squeaks or other noises persist, check that the unit is properly leveled. There are 2 leveling pads on the
bottom of the rear stabilizer, use a 14mm wrench (or adjustable wrench) to adjust the levelers.
