HOW TO ADJUST THE SEAT USING THE MULTI-POSITION HANDLEBARS
For effective
exercise, the
Seat (11) should
be at the proper
height. As you
pedal, there
should be a
slight bend in
your knees
when the pedals
are in the lowest
position. To
adjust the Seat,
first hold the
Seat and
remove the Seat Pin (35). Align one of the holes in
the Seat Post (10) with the hole in the Frame (1).
Insert the Seat Pin into the Frame and the Seat Post.
Caution: Make sure to insert the Seat Pin through
one of the holes in the Seat Post; do not Insert the
Seat Pin under the Seat Post.
HOW TO ADJUST THE PEDALING RESISTANCE
To vary the
intensity of your
exercise, the
pedaling resis- 25
tanca can be
adjusted. The
resistance is
controlledwith
the Resistance
Knob (25). To
increase the
resistance, tum
the Resistance Knob clockwise; to decrease the resis-
tance, turn the Resistance Knob counterclockwise.
BA'rrERY INSTALLATION
Before the console can be operated, two ""AA" bat-
tedes must be installed. If you have not installed bat-
tedes, see assembly step 4 on page 5.
Your exercise
cycle features
padded, multiple-
position handle-
bars. They are
designed to offer
a maximum
amount of cam-
fort while exer-
cising.
DESCRIPTION OF THE CONSOLE
The console features
five modes that pro-
vide instant exercise
feedback during your
workouts. The modes
are described below.
• Speed---Displays
your pedaling
speed, in miles per
hour.
• Time--Displays the
elapsed time. Note:
If you stop pedaling
for ten seconds or
longer, the time
mode will pause
until you resume.

cloth. Avoid spillingliquid on the console. Keep the
console out of direct sunlight or the display may be
damaged. Remove the batteries when stodng the
exercise cycle.
BATTERY REPLACEMENT
If the console does not function properly, the batteries
should be replaced. See assembly step 4 on page 5.
In addition, make sure that the console wire is con-
nected to the reed switchwire.
\
HOW TO TIGHTEN THE CRANK
If the arms of
the Crank (20)
become loose,
they should be
tightened in
order to prevent
excessive wear.
Loosen the
crank nut on
the left arm of
the Crank.
Place the end
of a standard
_Slotted
Cran_ Crank
screwdriver in one of the slots in the slotted crank nut.
Lightlytap the screwdriver with a hammer to turn the
slotted crank nut counterclockwise untilthe arms are
no longer loose. Do not overtighten the slotted
crank nut. When the slotted crank nut is properly
tightened, retighten the Crank Nut.

HOW TO ADJUST THE REED SWITCH
If the console does not display correct feedback, the
reed switch should be adjusted. In order to adjust the
reed switch, the Left Side Shield (12) must be remov-
ed. Remove the four Side Shield Screws (15) from the
Right Side Shield (13) and the three M4 x 16mm
Tapping Screws (30) from the bottom of the Left Side
Shield. Carefully slide the Left Side Shield forward off
the arm of the Crank (20) and remove it.

Next, locate the
Reed Switch (33).
Turn the crank until
the Magnet (46) is
aligned with the
Reed Switch.
Loosen but do not
remove the M4 x
16ram Screw (30).
Slide the Reed
Switch slightly clos-
er to or away from the Magnet. Retighten the Screw.
Tumthe crank for a moment. Repeat until the console
displays correct feedback. When the Reed Switch is
correctly adjusted, reattach the left side shield.
HOW TO ADJUST THE RESISTANCE STRAP
If there is notenough pedaling resistance when the
resistance knob is turned to the highest setting, the
Resistance Strap (17) may need to be adjusted.
To adjust the Resistance Strap, first turn the resis-
tance knob
to the low-
est setting.
Next, locate
and open
the Strap
Buckle (18)
on the
underside
of the side
shields.
Grip the
end of the Resistance Strap (17) and pull it back
slightly to remove any slack. While holding the end of
the Resistance Strap, fully close the Strap Buckle.
Tum the crank for a moment to make sure that there
is not too much resistance.
HOW TO ADJUST THE DRIVE BELT
The exercise cycle features a drive belt that must be
kept properly adjusted. If the belt causes excessive
noise or slips as you pedal, the belt should be
checked. To do this, the side shields must first be
removed. Refer to the instructions on this page and
remove the left side shield. Next, remove the right
side shield the same way.
Press down on
the center of the
Drive Belt (23)
between the front
and rear pulleys,
There should be
from 1/4" to 1/2"
of movement in
the center of the
Belt.
23
If the drive belt is
properly adjust-
ed, reattach the
side shields. If
the Belt needs to
be adjusted,
loosen the Axle
Nut (29) on each
side of the fly-
wheel. To tighten
the Belt, turn the
Adjustment Nuts
(27) clockwise; to loosen the Belt, turn the Adjustment
Nuts counterclockwise. Make sure that the Flywheel is
straight and tighten the Axle Nuts (29). Reattach the
side shields.

CONDITIONING GUIDELINES
The following guidelines will help you to plan your
exercise program. Remember that proper nutrition
and adequate rest are essential for successful results.
EXERCISE INTENSITY
Whether your goal is to burn fat or to strengthen your
cardiovascular system, the key to achieving the
desired results is to exercise with the proper intensity.
The proper intensity level can be found by using your
heart rate as a guide. The chart below shows recom-
mended heart rates for fat burning, maximum fat
burning, and cardiovascular (aerobic) exercise.
BPM HEART RATETRAINING ZONES
//m/mmm
20 30 40 _ _ _ 80
To find the proper heart rate for you, first find your age
on the bottom of the chart (ages are rounded off to
the nearest ten years). Next, find the three numbers
above your age. The three numbers are your "training
zone." The lowest number is the recommended heart
rate for fat burning; the middle number is the heart
rate for maximum fat burning; the highest number is
the heart rate for aerobic exercise.
Burning Fat
To burn fat effectively, you must exercise at a rela-
tively low intensity level for a sustained period of time.
During the first few minutes of exercise, your body
uses easily accessible carbohydrate calories for ener-
gy. Only after the first few minutes of exercise does
your body begin to use stored fat calories for energy.
If your goal is to burn fat, adjust the intensity of your
exercise until your heart rate is near the lowest num-
ber in your training zone as you exercise.
For maximum fat burning, adjust the intensity of your
exercise until your heart rate is near the middle num-
ber in your training zone as you exercise.
Aerobic Exercise
If your goal is to strengthen your cardiovascular sys-
tem, your exercise must be "aerobic." Aerobic exer-
cise is activity that requires large amounts of oxygen
for prolonged periods of time. This increases the
demand on the heart to pump blood to the muscles,
and on the lungs to oxygenate the blood. For aerobic
exercise, adjust the intensity of your exercise until
your heart rate is near the highest number in your
training zone.
HOW TO MEASURE YOUR HEART RATE
To measure your
heart rate, first exer-
cise for at least four
minutes. Then, stop
exercising and place
two fingers on your
wrist as shown. Take
a six-second heart-
beat count, and mul-
tiply the result by 10
to find your heart
rate. For example, if your six-second heartbeat count
is 14, your heart rate is 140 beats per minute. (A six-
second count is used because your heart rate will
drop rapidly when you stop exercising.)
WORKOUT GUIDELINES
Each workout should include the following three parts:
A warm-up, consisting of 5 to 10 minutes of stretch-
ing and light exercise. A proper warm-up increases
your body temperature, heart rate, and circulation in
preparation for exercise.
Training zone exercise, consisting of 20 to 30 min-
utes of exercising with your heart rate in your training
zone. (During the first few weeks of your exercise pro-
gram, do not keep your heart rate in your training
zone for longer than 20 minutes.)
9
Page 10
A cool-down, with 5 to 10 minutes of stretching. This
will increase the flexibility of your muscles and will
help to prevent post-exercise problems.
EXERClSE FREQUENCY
To maintain or improve your condition, plan three work-
outs each week, with at least one day of rest between
workouts. After a few months of regular exemise, you
may complete up to five workouts each week, if
desired. Caution: Be sure to progress at your own
pace and avoid overdoing it. Incorrect or excessive
training may result in injury to your health.
Remember, the key to success is make exercise a
regular and enjoyable part of your everyday life.
