GETTING STARTED
Read the Owner’s Manual before setting up the Johnson Fitness Bikes. Place the bikes
where they will be used before beginning the setup procedure.
MAKING A CHOICE OF SITE
STABILIZING THE BIKE
SETUP THE BIKE
JOHNSON BIKE C8000 / R8000 JOHNSON BIKE C8000 / R8000
The site should be well-lit and well-ventilated. Locate the Upright Bike C8000 or Recumbent
Bike R8000 on a structurally solid flat surface and kept a few feet from the wall or any
equipment. If the site has a heavy plush carpet, to protect the carpeting and machinery, you
should place a rigid plastic base under the unit.
Please do not place the Bike C8000 or R8000 in an area of high humidity, such as the vicinity
of a steam room, indoor pool, or sauna. Exposure to intensive water vapour or chlorine
could adversely affect the electronics, as well as other parts of the machine. To make
exercise a desirable daily activity for you, these two bikes should be in an attractive setting.
The straps are designed to fit your individual foot size and should be adjusted tight enough
to keep your feet from slipping. The pedals include spring-loaded clips for easy adjustment.
To tighten the strap, pull down the open end of the strap. To loosen the strap, push down
on the top of the clip and pull the strap up. Release the clip to lock in place.
After positioning the Bike in its intended location, check its stability by attempting to shake
it side to side. Shaking or wobbling indicates that your bike needs to be leveled.
Determine which leveler is not resting completely on the floor. Loosen the nut with one
hand to allow the leveler to rotate. Rotate the left or right leveler, and repeat the adjustment
as necessary until the bike is stable. Lock the adjustment by tightening the nut against the
rear foot support.

ADJUSTING THE SEAT
JOHNSON BIKE C8000 / R8000 JOHNSON BIKE C8000 / R8000
To determine whether or not the seat requires adjustment, sit on it and place the foot ankle
on the pedals. The knee should bend slightly when the pedal is at the lowest point of its
rotation. It should be possible to pedal without locking the knees or shifting in the seat. The
C8000 features a vertical ratchet seat adjustment system, which makes it easy and safe to
change the height of the seat quickly.
To raise the seat, pull the seat upward to the desired
height, and let it lock in place. Test and re-adjust the
seat height as necessary.
To lower the seat, first get off the bike. Holding the
seat, pull out the yellow seat post knob. Let the seat
slide down to the desired height and release the
yellow seat post knob. Test and re-adjust the seat
height as necessary.
RECUMBENT BIKE R8000
While seated on the R8000, an optimum position will allow movement through the bottom
of the stroke without locking the knees or shifting in the seat. The knees should have a
slight bend at the point of fullest leg extension.
If the seat needs to be adjusted, lift the spring-loaded seat lever on the right side of the seat
to make adjustments. Slide the seat forward or backward to desired location. Release the
spring-loaded seat lever and gently attempt to rock forward and backward to assure it is
locked in place. Check the seat distance again and re-adjust it if necessary.
On the C8000 and R8000, the user’s pedaling generates the power to initialize and display
information on the monitor. A minimum of 15 RPM (revolutions per minute) is required to
start and maintain enough power to keep the monitor functional. If the minimum RPM is
not maintained, the monitor will begin to shutdown. The C8000 and R8000 are able to
extend time to display the monitor, at the minimum RPM not maintained, if the bikes are
equipped with the battery. The bike saves its battery charge by moving into a shutdown
mode whenever PEDAL FASTER appears on the display.
NOTE: The battery is not equipped with the bike for a standard specification.
If your bike equipped with the battery receives inconsistent use, or long time periods
between use, the battery may require recharging. The adapter is an optional accessory for
recharging the unit. To purchase the optional battery and adapter please contact Johnson
Fitness or your local dealer.
SYMPTOMS OF A LOW BATTERY
If the bike has not been used for an extended period of time, the battery may require
recharging. Symptoms of a low battery can include:
• A “LOW BATTERY” message will appear on the monitor
• Backlighting on the LCD display will be disabled
• No one uses the bike for an extended period of time.
If the battery must be recharged, use the optional power adapter charging unit. The charger
should be connected to the bike for a minimum of eight hours to ensure a thorough
charge. If LOW BATTERY still appears on the display after full charging, the battery could be
extinct. Please check with an authorized service technician for replacing the battery.
UPRIGHT BIKE C8000
REPLACING THE BATTERY

you feel that the battery may need replacing, check with an
authorized service technician.
CAUTION:
The battery stored inside the unit contains hazardous
materials to the environment. Proper disposal of the battery

WORKOUT OVERVIEWSWORKOUT PARAMETER PROMPTS
This section lists the default value and value range of workout parameters appeared in the
PROMPT AREA, located in the bottom of WORKOUT PROFILE WINDOW. Before an exercise session,
each parameter prompt will appear here depending on different programs.
This chart lists the Johnson upright and recumbent bike’s pre-programmed workouts.

JOHNSON BIKE C8000 / R8000JOHNSON BIKE C8000 / R8000
Quick Start is the fastest way to begin exercising
and bypasses the setup prompts. After pressing
the QUICK START key, a constant-level workout
begins.
Warm-up is a low-intensity phase that brings the
heart rate into the lower end of the target zone
and increases respiration and blood flow to
working muscles.
Cool-down is a low-intensity phase that allows
the body to begin removing lactic acid, and
other exercise by-products, which build up in
muscles and contribute to soreness.
Manual is a constant intensity level unless it is
manually changed.
Hill Interval is an efficient workout by alternating
work intervals and recovery intervals.
Random Hill is an interval training workout that
occurs in no regular pattern or progression.
CONSTANT
WATTS
RANDOM
Constant Watts is designed to maintain your
watts expenditure at a constant level by
controlling pedaling resistance and prompting
you to pedal at a specified RPM. Watts level
may vary above and below your target watts
level during this program.
Random is a workout of constantly changing
intensity levels that occur in no regular pattern
or progression.

WORKOUT TIPS
1. Johnson Fitness strongly recommends seeing your physician for a complete physical
examination before beginning any fitness program. Know your physician-recommended
heart rate target zone. If, at any time while exercising, you experiences faintness,
dizziness, pain, or shortness of breathe, you must stop immediately.
2. To mount the bike, grasp the front stationary handlebars, sit on the seat and place your
shoes inside the pedal straps. When you are comfortably situated, begin pedaling. To
dismount the bike, stop pedaling, grasp the front stationary handlebars and get off the
seat.
3. The better position for riding the upright bike, the knee should bend slightly when
the pedal is at the lowest point of its rotation. For the recumbent bike, the knees should
have a slight bend at the point of fullest leg extension.
4. It is highly recommended that you always incorporate the warm-up and cool-down
period into your workout. Warm-up brings the heart rate into the lower end of the
target zone and increases respiration and blood flow to working muscles. Cool-down
takes time for a user’s heart rate to return to a resting state after vigorous exercise
and reduces the amount of lactic acid in muscle tissue.
WORKOUT SETUP STEPS
Different bike workouts require different setup procedure. This section provides details
for setting up any workout program.
1. Begin to pedal the bike.
2. Use the PROGRAM PLUS™ KEYS to enter the program, or use RIGHT / LEFT ARROW keys
to scroll to desired program. The program name is displayed in the PROMPT AREA.
3. Use the RIGHT / LEFT ARROW keys to scroll to desired parameter values displayed in the
PROMPT AREA.
4. Press the SELECT key to confirm each selection. Follow the steps to set up each workout.
Note: The PROGRAM PLUS™ KEYS with a symbol of plus “Ŕ” have couple of similar
workout options included. Press the key repeatedly to select the desired program.
Or, press the program key once and use RIGHT / LEFT ARROW keys to scroll to the
desired program.

JOHNSON BIKE C8000 / R8000JOHNSON BIKE C8000 / R8000
Time Goal sets exercise duration as the workout
goal. Once the objective is met, the workout
automatically goes into a cool-down phase and
ends afterward.
Distance Goal is designed to build endurance in
a certain distance. Once the objective is met,
the workout automatically goes into a cool-down
phase, and ends afterward.
Calories Goal is designed to burn a certain
number of selected calories. Once the objective
is met, the workout automatically goes into a
cool-down phase and ends afterward.
Target HR is a higher intensity workout for
maintaining a heart rate to achieve maximum
exercise results. The user must wear a heart
rate chest strip, or keep hands on contact heart
rate grips continuously. The program adjusts
the intensity level, based on the actual heart
rate, to maintain the rate at 80 percent of the
theoretical maximum.
Weight Loss is a low-intensity workout for
burning the body’s fat reserves. The user must
wear a heart rate chest strip, or keep hands on
contact heart rate grips continuously. The
program adjusts the intensity level, based on
the actual heart rate, to maintain the rate at 65
percent of the theoretical maximum.
Fit Test measures cardiovascular fitness and
can be used to monitor improvements in your
endurance.

QUICK START
Press the "QUICK START" key and the WORKOUT PROFILE WINDOW will display "3, 2, 1,
