1.2 SETUP
Read the entire User Manual before setting up the exercise bike.
WHERE TO PLACE THE EXERCISE BIKE
Following all safety instructions in Section 1.1, move the bike to the location in which it will be used. See Section 7, titled
Specifications, for the dimensions of the footprint. Allow a distance of four feet, or 120 centimeters, between the bike and
other objects or surfaces on either side.
HOW TO STABILIZE THE EXERCISE BIKE
After placing the bike in position, check the unit's stability by attempting to rock it in all directions. Any slight rocking indi-
cates that the unit must be leveled. Determine which foot is not resting completely on the floor. Loosen the jam nut with
an open-end 17mm wrench, and rotate the stabilizing foot to lower it. Verify that the bike is stable, and repeat the adjust-
ment as necessary until the unit no longer rocks. Lock the adjustment by tightening the jam nut against the stabilizer bar.
8

HOW TO ADJUST THE SEAT TO ENSURE CORRECT BIOMECHANICAL POSITIONING
Proper seat positioning minimizes unecessary leg muscle fatigue. To determine whether or not the seat requires adjust-
ment, sit on it and place the balls of the feet on the pedals. The knee should bend slightly when the pedal is at the furthest
point in its rotation, relative to the body. The user should be able to pedal without locking the knees or shifting in the seat.
Adjusting the seat on the C35 upright bike: The bike post features a vertical locking pin seat adjustment system,
which makes it easy and safe to change the height of the seat quickly. To raise the seat, first get off the bike. Hold the
seat, turn the spring-loaded knob on the right of the seat post once counter-clockwise to loosen it, and pull out the knob
to unlock the post from its present position. Pull the seat upward to the desired height, and release the knob to let it lock
into place. Turn the knob once clockwise to tighten it. Test and re-adjust the seat height as necessary.
To lower the seat, first get off the bike. Hold the seat, turn the spring-loaded knob on the right of the seat post once
counterclockwise to loosen it, and pull out the knob to unlock the post from its present position. Let the seat slide down
to the desired height, and release the knob to let it lock into place. Turn the knob once clockwise to tighten it. Test and
re-adjust the seat height as necessary.
CAUTION: When using the height adjustment mechanism to change the height of a partially raised seat, hold the seat to
prevent it from falling on the hand.
CAUTION: Do not attempt to lock the seat at a position higher than the minimum insertion depth marked on the seat post.
9

Adjusting the seat on the R35 recumbent bike: Lift the spring-loaded adjusting handle located on the right side of the
seat. Slide the seat forward or backward as necessary to the proper position and release the pin to complete engage-
ment. Gently rock the seat forward and backward to ensure that it is locked into place. Check the seat distance again
and readjust it if necessary.
NOTE: If the seat carriage rocks excessively, use a wrench to loosen the jam nut (A) on either side of the seat carriage.
With another wrench, tighten the adjustment roller on the inside of the carriage until it is snug, but do not over-tighten it.
Then, while holding the roller in place, tighten the lock nut. Repeat the procedure for the other side of the seat carriage.
CAUTION: Do not attempt to adjust the seat while pedaling the bike. Doing so, or failing to insert the seat pin
completely may result in an uncomfortable workout or cause injury.
10

HOW TO ADJUST THE PEDAL STRAPS
The bike pedal safety straps keep the user's shoes on the pedals during a workout.
The straps should fit comfortably, but they also should be tight enough to prevent
shoes from slipping at any point in the pedaling rotation. Before working out, the user
should test and adjust the tightness of the straps.
The straps can be adjusted to fit a variety of shoe sizes. Each strap is held in place by a
spring-loaded clip that is connected to the outer edge of each pedal. To tighten a strap,
simply pull the loose end of the strap down. It automatically locks into place with each
pull. To loosen a strap, press down on the top of the clip and pull the strap up. Release
the clip to lock the strap into place. Test the adjustment, and change if necessary.
HOW TO ADJUST THE LUMBAR SUPPORT ON THE R35 RECUMBENT BIKE
The back pad can be adjusted to provide additional lumbar support. Twist the knob
located on the right side of the back pad clockwise to increase lumbar support. Three
levels of additional lumbar support are available.
STARTING UP THE BIKE
To power up the exercise bike, simply start pedaling. Once the unit’s power is on, the console display lights up, making it possi-
ble to select a workout or to begin a QUICK START workout. See Section 4.2, titled Using the Workouts, for more information.

3HEART SYNCTM EXERCISE PROGRAMS
3.1 WHY HEART SYNC WORKOUTS?
Research shows that maintaining a specific heart rate while exercising is the optimal way to monitor the intensity of a
workout and to achieve maximum results. That is the idea behind the Heart Sync approach to exercise.
Heart Sync workouts identify an exerciser's ideal heart rate range for burning fat or increasing cardiovascular fitness.
The values within the range depend on the workout.
NOTE: Consulting a fitness trainer is recommended for defining specific fitness goals and
designing a workout program.
The exercise bike features five exclusive workouts designed to take full advantage of the bene-
fits of Heart Sync exercise: FAT BURN,CARDIO,HEART RATE HILL, HEART RATE INTER-
VAL, or EXTREME HEART RATE. For detailed information about these workouts, see Section
4, titled The Workouts.
During one of these workouts, grasp the handpulse sensors or wear the wireless heart rate chest
strap to enable the exercise bike’s on-board computer to monitor the heart rate. The computer
automatically adjusts the resistance level to maintain the target heart rate* based on the actual
heart rate. To change the target heart rate during a workout, use the ARROW keys.
16

3.2 HEART RATE MONITORING
THE HAND PULSE SENSOR SYSTEM
The hand pulse sensors (A) are the built-in heart rate monitoring system on the exercise bike. During a workout, grasp
the sensors that are set into the handlebars. For an accurate reading, use a comfortable grip. The console displays the
heart rate after 10 to 15 seconds.
Upright Model C35Recumbent Model R35
NOTE: Excessively squeezing the hand pulse sensors will not improve the heart rate reading.
17

THE WIRELESS HEART RATE CHEST STRAP
The exercise bike is equipped with wireless, a heart rate monitoring system in which electrodes, pressed against the skin,
transfer heart rate signals to the exercise bike console. These electrodes are attached to a wireless heart rate chest strap that
the user wears during the workout. The chest strap is included with the exercise bike.
See the diagram below for correct positioning of the strap. The electrodes (A), which are the two grooved surfaces on the
underside of the strap, must remain wet to transmit accurately the electrical impulses of the heart back to the receiver. Moisten
the electrodes. Then, secure the strap as high under the chest muscles as possible. The strap should be snug, but comfortable
enough to allow for normal breathing.
The transmitter strap delivers an optimal heart rate reading when the electrodes are in direct contact with skin. However, it also
functions properly through a thin layer of wet clothing.
If it becomes necessary to re-moisten the chest strap electrodes, grasp the center of the strap, pull it away from the chest to
expose the two electrodes, and moisten them.
NOTE: Using the wireless chest strap will provide more accurate heart rate readings than the hand pulse sensors.

4THE WORKOUTS
4.1 WORKOUT OVERVIEWS
This section lists the exercise bike’s pre-programmed workouts. For more detailed information, see Section 4.2, titled
Using the Workouts.
QUICK START is the fastest way to begin exercising, and it bypasses the steps involved in selecting a specific workout
program. After the QUICK START key is pressed, a constant-level workout begins. The intensity level does not change
automatically.
HILL is an interval-training workout combining “hills” and “valleys” of different intensity levels, which is proven to provide
effective, time-efficient cardiovascular results.
RANDOM is an interval training workout of constantly changing intensity levels that occur in no regular pattern or pro-
gression.
MANUAL is a workout in which the intensity level does not change automatically.
SPEED TRAINER coaches the user with text messages to increase or decrease the speed at different time intervals. The user
has the ability to adjust resistance level at any time during a workout.
EZ RESISTANCE features a gradual, subtle increase in resistance, lowering perceived exertion. A peak in resistance is
followed by an equally subtle decrease in resistance.
FAT BURN is a low-intensity workout for burning the body’s fat reserves. The user must grasp the hand pulse sensors
or wear a wireless heart rate chest strap. The workout program automaticaly adjusts the intensity level, based on the
actual heart rate, to maintain the user’s heart rate at 65 percent of the theoretical maximum.
CARDIO is a higher intensity workout for more fit users, emphasizing cardiovascular benefits and maximum fat burning. The
user must grasp the hand pulse sensors or wear a wireless heart rate chest strap. The workout program automatically
adjusts the intensity level, based on the actual heart rate, to maintain the user’s heart rate at 80 percent of the theoretical
maximum.
