THEORY OF OPERATION
The Lifecycle recumbent bikes are stationary exercise bicycles that provide a scientific method of improving body
fitness and endurance through its unique “12 or 24 MINUTE RIDE TO VIGOROUS HEALTH.”
Computerized state-of-the-art electronics have been engineered to satisfy a range of personalized fitness needs of
the beginner to the needs of the most advanced fitness enthusiast.
The Lifecycle concept is based on the self-motivational principle of INTERVAL TRAINING WITH PROGRESSIVE
OVERLOAD. During the HILL and RANDOM exercise programs, the workload against which you are pedaling is
periodically changed by the built-in computer resulting in an automatic increase or decrease in pedal resistance.
This simulates riding up and down virtual “hills,” which are visualized on the display console with columns of “lights”
that move from right to left.
With features like the RACE program, Fit Test, level 1 through 20 resistance - almost 25% easier than the level 1
found on earlier editions of the classic Lifecycle exercise bike and much more challenging for the experienced rider.
Also a seat adjustment which allows a wider range of selection to accommodate most anyone.
The ability to select a program to match your particular needs is what distinguishes Lifecycle bikes as the world’s
most popular physical conditioning device. Its user-flexibility means that you will never outgrow the innumerable
challenges the Lifecycle exercise bike has to offer.
The beginner starts with basic programs, then improves his level of fitness at his own rate while constantly
challenging himself to the next level. For well-conditioned individuals, the advanced programs offer more difficult
modes of training. In fact, many world-class athletes use Lifecycle bikes to maintain peak levels of conditioning.

How To...ADJUST SEAT ROLLER ADJUSTMENT
Tools Required: Two torque wrenches, combination wrench set
1. The SEAT ROLLERS are adjusted to a specified
resistance load. If the seat moves too freely with
excessive side-to-side movement, then the seat
rollers must be adjusted as follows.
2. Using a ½ inch wrench, loosen all four(4) SEAT
ROLLER CLAMP NUTS, then retighten by hand.
3. Make initial adjustments to the SEAT ROLLERS on the
right side of the unit first. This is done to ensure that
the two right guide rollers are properly seated in the Vchannel of the seat extrusion. Once the SEAT
ROLLERS on the right side are adjusted, then proceed
to adjust the seat rollers on the left side of the unit.
Right Side
NOTE: Step 4 requires use of two inch pound torque
wrenches. One to maintain a resistance load against the
TAKE-UP ROLLER and the other to torque the ROLLER
CLAMP NUT.
4. Starting with the right side SEAT ROLLERS, adjust the
first TAKE-UP ROLLER NUT to 60-65 in. lbs. in a
clockwise direction. Observe that the ROLLER CLAMP
NUT will move up. This indicates that the seat roller is
being forced up against the extrusion. Continue to
maintain the 60-65 in. lbs. resistance load on the takeup roller, and secure the seat roller position by
tightening the ROLLER CLAMP NUT from 100-120 in.
lbs. Repeat this procedure for other remaining right
roller. Once the right side is adjusted, repeat this
procedure for the left side. Always set the right side
seat rollers first. Failure to do so, will result in side-toside seat movement.
5. With all SEAT ROLLERS adjusted, test operation of the
seat assembly for a 15-25 lbs. pulling force and to
insure that no side-to-side movement exists. Repeat
this procedure as required.

Removing the existing Lifepulse digital heart rate sensors:
1. Using a standard flat screwdriver, pry off the stainless steel sensor
furthest away from you as if you were the user gripping the Lifepulse
heart rate monitoring sensors (if screw access holes are already provided
in the sensor you wish to replace, simply remove the two screws and
continue to Step 2). This will be the sensor on which your fingertips rest
during use. This sensor will be referred to as the “ground sensor” (black
or green wire) hereafter in these instructions. The sensor closest to the
user, on which the palm rests, will be referred to as the “signal outputsensor” (red or white wire).
2. Pull the ground sensor gently away from the molded plastic
housing, to which it was attached, to reveal a wire harness (black
or green wire) with a Faston connector attached to the back of
the sensor. Unplug the Faston connector from the groundsensor.
3. Loosen and remove the two screws securing the two sensor
molded plastic housings to each other on the assembly. Lift the
molded plastic housings away from each other and unplug the
Faston connector attached to the back of the signal outputsensor (red or white wire).

How To... REPLACE THE DIGITAL HEART RATE SENSORS (continued)
Installing the new Lifepulse digital heart rate sensors:
4. Plug the Faston connector (red or white wire) to the back of the new, pre-assembled signal output sensor
assembly (this will be the assembly without the screw access holes in the sensor) and locate it into position.
This sensor will be the sensor on which the palm rests during use.
5. Plug the Faston connector (black or green wire) to the back of the new, pre-assembled ground sensor
assembly (this will be the assembly with the screw access holes in the sensor) and locate it into position. This is
the sensor on which the fingertips rest during use.
6. Install the two screws through the access holes in the ground sensor and torque to 5 - 7 in. Lb. .
7. Repeat Steps 1 through 6 to remove and replace the second set of sensors included in the kit.

How To... REPLACE THE DIGITAL HEART RATE PC BOARD (LC9500HR)
Tools Required: Phillips screwdriver, pliers
1. Remove the four SCREWS securing the DISPLAY CONSOLE to the DISPLAY CONSOLE BRACKET.
2. Unplug the 10-PIN CONNECTOR, 4-PIN CONNECTOR, and the 3-PIN CONNECTOR from the back of the
DISPLAY CONSOLE.
3. Remove the SCREWS securing the back of the DISPLAY CONSOLE to the OVERLAY FACE-PLATE. Set the
OVERLAY face down on a non-abrasive, flat surface.
4. Ground yourself to the machine by attaching one end of a DISPOSABLE ANTI-STATIC GROUNDING STRAP
to your wrist and the other to a suitable grounding point on the exercise bike (e.g.: the metal part of the pedal
crankshaft).
Display Console model
shown for reference only.
5. Use the pliers to squeeze the tips of the five SPACERS, one at a time, to allow removal of the HEART RATE
PC BOARD. Before lifting the HEART RATE PC BOARD from position, be aware that an 8-PIN
CONNECTOR is also securing the back of the board in place.
6. Replace any damaged SPACERS with those included in the kit.
7. Reverse Steps 1 through 5 to replace all parts in their proper positions.
