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 6, 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 unnecessary 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 C15upright 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 R15 recumbent bike: Lift the spring-loaded adjustment 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
engagement. 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: The seat carriage can be adjusted if it is too tight and does not slide freely or if
it is too loose and rocks excessively.
To adjust the fit of the carriage when there is excessive rocking 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.
Then, while holding the roller in place, tighten the lock nut. Repeat the procedure for the
other side of the carriage.
To adjust the fit of the carriage when it does not slide freely, use a wrench to loosen the
jam nut (A) on either side of the seat carriage. WIth another wrench, loosen the adjust-
ment roller on the inside of the carriage until it can move freely, but do not excessively
loosen. Then, while holding the roller in place, tighten the lock nut. Repeat the proce-
dure 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.

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.
STARTING UP THE BIKE
See Section 6, titled Specifications, for power requirements. Insert the AC adapter into an electrical outlet that has been
properly installed and grounded in accordance with all local codes and ordinances.
To power up the exercise bike, simply start pedaling or press any key on the console. Once the unit’s power is on, the con-
sole display lights up, making it possible to select a workout or to begin a MANUAL workout using QUICK START MANU-
AL MODE. See Section 3.2, titled Setting Up and Using the Workouts, for more information.

3THE WORKOUTS
3.1 WORKOUT OVERVIEWS
This section lists the exercise bike’s pre-programmed workouts. For more detailed information, see Section 3.2, titled
Setting Up and Using the Workouts.
QUICK START MANUAL MODE is the fastest way to begin exercising, and it bypasses the steps involved in selecting a
specific workout program. After the START key is pressed, a constant-level workout begins. The resistance level does
not change automatically.
INTERVAL combines “hills” and “valleys” of different resistance levels. Raising and lowering the heart rate in this
manner is proven to efficiently promote fat burn and cardiovascular endurance.
RANDOM provides a completely random workout profile of “hills” and “valleys” every time the user selects this workout.
Endless variety reduces boredom.
MANUAL is a workout in which the resistance level does not change automatically.
PEAK maintains a constant resistance level throughout the workout. Intended to burn fat.
SLOPE gradually increases resistance so user is less aware of the physical demand. Helps user slowly build-up to
higher resistance levels and improve cardiovascular endurance.
CHALLENGE maintains a high resistance level throughout the workout. Challenges the user to a high intensity workout
that promotes cardiovascular endurance.
17

3.2 SETTING UP AND USING THE WORKOUTS
To activate the console, press any key, or simply start pedaling. When the console display lights up, either select
QUICK START MANUAL MODE, or select a specific workout. Setting up a specific workout involves four steps,
which are described in this section:
1. Selecting a workout
2. Entering a workout duration
3. Selecting a level
4. Starting the workout (pressing START or ENTER)
SELECTING AND USING QUICK START MANUAL MODE

EXPLANATION OF RESISTANCE LEVEL
The difficulty level table shows the resistance level range at each difficulty level. Since some workouts have predeter-
mined profiles, a resistance level range had to be created. This allows the user to set a difficulty level of 1 - 9, which will
adjust the entire workouts intensity level.
19

STARTING A WORKOUT
After accepting a difficulty level, press START to begin the workout.
USING WORKOUTS IN PROGRESS
The exercise bike MANUAL program features 16 resistance levels, with “1” being the easiest and “16” being the most
difficult. The exercise bike RANDOM, SLOPE, INTERVAL, PEAK, and CHALLENGE programs feature 9 difficulty levels,
with “1” being the easiest and “9” being the most difficult. While a workout is in progress, it is possible to change the
level of the overall workout. To do so, simply press the UP or DOWN arrow keys repeatedly until the DATA DISPLAY
window shows the desired level. That change remains in effect for the entire workout or until the level is changed again.
NOTE: The exercise bike features speed-dependent braking resistance. For a set resistance level on the monitor,
the resistance increases with the user’s speed. The computer makes no adjustments to maintain the resistance level
based on the user’s speed.
PAUSING A WORKOUT
To pause a workout-in-progress, press the STOP key, or simply stop pedaling for 25 seconds. A workout can remain
in pause mode for a maximum duration of five minutes. If a paused workout is not resumed before the five-minute
pause duration ends, the console shuts down, and the paused workout information is lost. To resume a paused workout,
press the START key or simply begin pedaling again.
RESETTING A WORKOUT
To reset a workout, press the STOP key, and hold it for three seconds. This deletes the current workout and makes it
possible to set up a new workout.
REVIEWING A COMPLETED WORKOUT
When a workout reaches the end of its duration, the console emits four consecutive beeps. At this point, it is possible to
review summary data for the completed workout, including total calories burned and distance traveled, by pressing the
SCROLL key and reading the results in the DATA WINDOWS. Afterward, press the STOP key to return to the workout-
select mode.
