BASIC OPERATION
LOCATION OF THE EXERCISE BIKE
Place the exercise bike on a level surface. There should be one foot in front
of the exercise bike for the power cord. For ease of access, there should be
an accessible space preferentially on both sides of the exercise bike equal to
2 ft (0.6 meters) to allow a user access to the machine from either side. Do
not place the exercise bike in any area that will block any vent or air
openings. The exercise bike should not be located in a garage, covered patio,
near water or outdoors.
MOVING THE EXERCISE BIKE
Your exercise bike has a pair of transport wheels built into the front
stabilizer tube. Remove the power supply before attempting to move the bike.
WARNING!
Our exercise bikes are heavy, use care and additional help if necessary when
moving. Failure to follow these instructions could result in injury.
LEVELING THE EXERCISE BIKE
Your exercise bike should be level for optimum use. Once you have placed your
exercise bike where you intend to use it, raise or lower one or both of the
adjustable levelers located on the bottom of the frame. A carpenter’s level is
recommended. Once you have leveled your exercise bike, lock the levelers in
place by tightening the nuts against the frame. Actual levelers may differ
from image and may not include the lock.
POWER
Your exercise bike is powered by a power supply. The power must be plugged
into the power jack, which is located in the front of the machine near the
stabilizer tube. Unplug cord when not in use.
WARNING!
Never operate product if it has a damaged cord or plug, if it is not working
properly, if it has been damaged, or immersed in water. Please reference
contact information on the INFORMATION CARD for assistance.
UPRIGHT BIKES: firmly grasp the handlebars, carefully tip toward you, and
roll on the transport wheels.
RECUMBENT BIKES: firmly grasp the steel portion of the rear stabilizer tube, carefully lift and roll on the transport wheels.
PROPER USAGE
To determine proper seat position, sit on the seat and position the ball of
your foot on the center of the pedal. Your knee should bend slightly at the
furthest pedal position. You should be able to pedal without locking your
knees or shifting your weight from side to side. Adjust pedal straps to
desired tightness.
UPRIGHT SEAT ADJUSTMENT
For upright bikes with an adjustment lever: To raise the seat height, pull the
seat upward. To lower the seat, locate the adjustment lever under the seat and
pull the lever up to slide the seat down. Release lever and allow to lock into
place. Please check to be sure seat post is locked in place before each use.
For upright bikes with a locking seat adjustment knob: To adjust, get off the
bike seat and loosen the adjustment knob by turning it two half turns counter-
clockwise. Pull out the knob to unlock the post, and adjust the post up or
down to the desired setting. Release the knob to lock in place. Turn the knob
clockwise until tightened. Please check to be sure seat post is locked in
place before each use.
RECUMBENT SEAT ADJUSTMENT
For recumbent bikes with an adjustment lever: To adjust the seat position,
locate the lever under the seat before you mount the bike. Place your right
hand on the adjustment handle under the seat. Place feet on the ground while
seated and slide forward if needed. Place feet on pedals, gently lift lever
under the seat. Using legs, slowly push and slide the seat up or down to a
position that puts you in a comfortable pedaling range (one that keeps a
slight bend in your knee while your legs are in the extended position).
Release lever and allow to lock into place. For recumbent bikes with a locking
seat adjustment handle: Turn the handle up into its middle position making the
handle feel loose. Then, slide the seat to a position that puts you in a
comfortable pedaling range (one that keeps a slight bend in your knee while
your legs are in the extended position). Lock the mechanism by rotating it
down until handle tightens.
RECUMBENT MESH SEAT BACK ADJUSTMENT
Some recumbent bikes are equipped with a tilting mesh seat back. Tilt
adjustments are made with a rotating lever on the user’s right side, located
slightly behind the handlebar. Not all mesh seat backs have an adjustment
lever so check the ASSEMBLY GUIDE.
To adjust the tilt angle of the seat back, rotate the lever down (counterclock
wise) and lean back on the mesh seat back until the desired position is
achieved. When the position is set, rotate the lever upward (clock wise) until
it is snug. The seat back comes quipped with a spring return system to return
the seat back to its original position when the adjustment lever is released
and the user is not leaning against the seat back.
TROUBLESHOOTING
COMMON PRODUCT QUESTIONS
ARE THE SOUNDS MY EXERCISE BIKE MAKES NORMAL?
Our exercise bikes are some of the quietest available because they use belt
drives and friction free magnetic resistance. We use the highest grade
bearings and belts to minimize noise. However, because the resistance system
itself is so quiet, you will occasionally hear other slight mechanical noises.
Unlike older, louder technologies, there are no fans, friction belts, or
alternator noises to mask these sounds on our exercise bikes. These mechanical
noises, which may or may not be intermittent, are normal and are caused by the
transfer of significant amounts of energy to a rapidly spinning flywheel. All
bearings, belts and other rotating parts will generate some noise which will
transmit through the casing and frame. It is also normal for these sounds to
change slightly during a workout and over time because of thermal expansion of
the parts.
WHY IS THE EXERCISE BIKE I HAD DELIVERED LOUDER THAN THE ONE AT THE
STORE?
All fitness products seem quieter in a large store showroom because there is
generally more background noise than in your home. Also, there will be less
reverberation on a carpeted concrete floor than on a wood overlay floor.
Sometimes a heavy rubber mat will
help reduce reverberation through the floor. If a fitness product is placed
close to a wall, there will be more reflected noise.
HOW LONG WILL THE DRIVE BELT LAST?
The computer modeling we have done indicated virtually thousands of
maintenance free hours. You should not have to replace the belt as long as you
have the exercise bike.
CAN I MOVE THE EXERCISE BIKE EASILY ONCE IT IS ASSEMBLED?
Your exercise bike has a pair of transport wheels built into the front
stabilizer tube. Please follow the MOVING THE EXERCISE BIKE section to
transport your exercise bike. It is important that you place your exercise
bike in a comfortable and inviting room. Your exercise bike is designed to
use minimal floor space. Many people will place their exercise bikes facing
the TV or a picture window. If at all possible, avoid putting your exercise
bike in an unfinished basement. To make exercise a desirable daily activity
for you, the exercise bike should be in a comfortable setting.
BASIC TROUBLESHOOTING
PROBLEM: The console does not light up.
SOLUTION: Verify the following:
- The outlet the machine is plugged into is functional. Double check that the breaker has not tripped.
- The correct power cord is being used. Only use the power cord provided. Test the voltage on the power cord to verify it provides the specified output voltage from the label.
- The power cord is not pinched or damaged and is properly plugged into the outlet AND the machine.
- Unplug power cord, remove the console and check that all connections to the console are secure and not damaged or pinched. Unplug then reconnect the console cable.
PROBLEM: The console lights up but the Distance/Watts/RPMs do not count.
SOLUTION: Verify the following:
- Unplug power cord, remove the console and check that all connections to the console are secure and not damaged or pinched. Unplug then reconnect the console cable.
- If doing the above does not fix the problem, the speed sensor and/ or magnet may have become dislodged or damaged.
PROBLEM: The resistance levels seem to be incorrect, seeming too hard or
too easy.
SOLUTION: Verify the following:
- The correct power cord is being used. Only use the power cord provided.
- Reset the console and allow the resistance to reset to the default position. Restart and retry the resistance levels.
PROBLEM: The exercise makes a clicking noise or feeling from the pedals.
SOLUTION: Verify the following:
- Verify the bike is on a level surface.
- Remove the pedals, apply blue threadlocker to the threads and re-tighten the pedals using an open wrench.
PROBLEM: The exercise bike makes a squeaking or chirping noise.
SOLUTION: Verify the following:
- The exercise bike is on a level surface.
- Loosen all bolts attached during the assembly process, grease the threads, and tighten again.
FOR CYCLES WITH SPEAKERS:
PROBLEM: When MP3 player is connected there is no sound coming from the
speakers or the speakers sound fuzzy.
SOLUTION: Make sure audio cable is plugged in securely to both the
console and MP3 Player jacks.
HEART RATE (GRIP-PULSE ONLY)
Check your exercise environment for sources of interference such as
fluorescent lights, computers, underground fencing, home security systems or
appliances containing large motors. These items may cause erratic heart rate
readouts.
You may experience an erratic readout under the following conditions:
- Gripping the heart rate handlebars too tight. Try to maintain moderate pressure while holding onto the heart rate handlebars.
- Constant movement and vibration due to constantly holding the heart rate handlebars while exercising. If you are receiving erratic heart rate readouts, try to only hold the grips long enough to monitor your heart rate.
- When you are breathing heavily during a workout.
- When your hands are constricted by wearing a ring.
- When your hands are dry or cold. Try to moisten your palms by rubbing them together to warm.
- Anyone with heavy arrhythmia.
- Anyone with arteriosclerosis or peripheral circulation disorder.
- Anyone whose skin on the measuring palm is especially thick.
