Assembly Instructions
STEP 4:

This section will instruct you on how to properly use and make adjustments to
components on the bike. Items which will be covered include seat adjustment,
handlebar adjustment, resistance adjustment, using the emergency brake, pedal
strap adjustment, dismounting the bike, moving the bike, and leveling the bike.
NOTE:
Properly assembling the equipment before use is very important, please be sure to
follow all instructions as detailed in the assembly instructions section of the owner’s
manual.
SEAT ADJUSTMENT
Proper seat height helps to ensure the maximum exercise efficiency and comfort
while reducing the risk of injury. Adjusting the seat forward and backwards allows the
rider to target and work lower body muscle groups.
SEAT HEIGHT ADJUSTMENT
Do NOT raise the seat height above the STOP mark on the seat post.
1. To adjust the seat height, turn the Seat Height Adjustment Knob (6)
counter-clockwise and pull it outward to release it. Raise or lower the seat post to the
desired height, release the Seat Adjustment Knob gently until it engages a preset hole
along the seat post. Turn the Seat Height Adjustment Knob (6) clockwise to tighten
and secure it into place.
2. Rotate the crank so that the pedals are at the 12 and 6 o’clock position.
3. Place your foot into the toe cage of the pedal closest to the floor and mount the bike.
Ensure that the ball of your foot is over the center of the pedal. If your leg is too
straight or your foot cannot touch the pedal you will need to lower the seat. If your leg
is bent too much you will need to raise the seat.
4. If necessary, you may need to make several different seat height adjustments in
order to find the most comfortable position. Repeat the instructions of Steps 1, 2 & 3
until you locate the desired seat position.
5. When you have obtained the desired seat position, be sure to note the number on
the seat post for future reference.
User Instructions

SEAT SLIDER ADJUSTMENT
1. Turn the Seat Slider Adjustment Knob (80) count-clockwise and pull it outward
to release it. Slide the Seat Slider (3) forward or backwards to the desired position.
2. Once the seat has been set in the desired position, turn the Seat Slider
Adjustment Knob (80) clockwise to tighten and secure the Seat Slider (3) in place.
3. If necessary, you may need to make several different adjustments to the Seat
Slider (3) in order to find the most comfortable position. Repeat the instructions of
Step 1 & 2 until you locate the desired seat position.
4. When you have obtained the desired seat position, be sure to note the number on
the seat slider for future reference.
HANDLEBAR ADJUSTMENT
Proper handlebar height helps to ensure the maximum exercise efficiency and
comfort. Adjusting the handlebars to a higher level will give the rider more of an
upright position, lowering it will result in a more prone position. If there is any
discomfort in your back during exercise, the handlebars should be adjusted.
HANDLEBAR HEIGHT ADJUSTMENT
Do NOT raise the handlebar height above the STOP mark on the handlebar post
1. Begin by positioning the handlebars at the same height as the seat. Mount the bike
and assume a riding position. Use this position to obtain a feel for the location of the
handlebars as well as your level of comfort.
2. Turn Handlebar Adjustment Knob (81) counter-clockwise and pull it outward to
release it. Raise or lower the Handlebar Post (9) to the desired height, release the
Handlebar Adjustment Knob gently until it engages a preset hole along the handlebar
post. Turn the Handlebar Adjustment Knob (81) clockwise to tighten and secure it
into place.
3. If necessary, you may need to make several different handlebar height adjustments
in order to find the most comfortable position. Repeat the instructions of Steps 1 & 2
until you locate the desired handlebar position.
4. When you have obtained the desired handlebar position, be sure to note the
number on the handlebar post for future reference.
User Instructions

RESISTANCE ADJUSTMENT
Resistance can easily be adjusted at any time while riding in order
to change the intensity of the workout.
Turn the Resistance Knob (No. 58) clockwise (+) to increase the
level of resistance. Turn the Resistance Knob (No. 58)
counter-clockwise (-) to decrease the level of resistance.
EMERGENCY BRAKE
In case of emergency or before dismounting the bike press
directly down on the Resistance Knob (No. 58) to enforce the
brake system and bring the flywheel to an immediate stop.
PEDAL STRAP ADJUSTMENT
Feet should be securely positioned in the toe clips during exercise. Place your feet as
far forward into the toe-clips as you can. With your feet in place, grasp the pedal strap
and pull it upward to tighten the toe-clip cage then insert the strap back into the hoop
of the toe-clip. Repeat this process to secure your other foot.
LEVELING THE BIKE
In order to assure a smooth and comfortable workout, you must ensure that the
stability of the bike is correct. If you notice that the bike is unbalanced during use, you
may adjust the leveler foot located beneath the front and rear stabilizers of the bike.
To do so, use the Combination Wrench (No. C) to loosen the Hex Nut (No. 19) by
turning it clockwise. With the nut loosened, rotate the Leveler Foot (No. 20) until it
sits level with the surface that the bike is on. When you have finished adjusting the
leveler foot, re-tighten the Hex Nut (No. 19) by turning it counter-clockwise using the
Combination Wrench (No. C). If necessary, repeat this process to adjust the
remaining leveler feet on the bike.
User Instructions

DISMOUNTING THE BIKE
WARNING:
Do NOT attempt to dismount or remove your feet from the pedals until both the
flywheel and the pedals/crank have come to a complete stop. Failure to follow this
warning may lead to loss of control and/or serious injury.
Here are a few examples of how to safely and properly dismount the bike:
1. Reduce the pedal speed until the pedals/crank come to a complete stop.
2. Increase the resistance until the pedals/crank come to a complete stop.
3. Push and hold the resistance knob down to engage the Emergency Brake function,
hold until the pedals/crank come to a complete stop.
MOVING THE BIKE
To move the bike, first make sure that the
Handlebar (No. 8) is properly secured. If the
handlebar is loose, tighten the Handlebar
Adjustment Knob (No. 81) to secure it.
Next, stand at the front of the bike so that
you’re directly in front of the handlebars.
Firmly grasp each side of the handlebar,
place one foot on the stabilizer and tilt the
bike towards you until the transportation
wheels on the front stabilizer touch the
ground. With the wheels securely on the
ground, move the bike to the desired
location.
NOTE: When moving the bike, always move with caution as unexpected impacts or
dropping the bike may affect its operation.

Maintenance

NOTE:
Using the ASUNA Commercial Indoor Cycling Bike will provide you with several
benefits. It will improve your physical fitness, tone your muscles, and in conjunction
with calorie controlled diet, it can also help you lose weight.
1. THE WARM-UP PHASE:
This stage helps to get the blood flowing around the body while also loosening and
preparing the muscles for workout. This phase will also reduce the risk of cramp and
muscle injury. It is advisable to do a few stretching exercises as shown below. Each
stretch should be held for approximately 30 seconds, do not force or jerk your
muscles into a stretch, if it hurts, STOP!
2. THE EXERCISE PHASE:
Effort is the key in this phase. After regular use, the muscles in your legs will become
stronger as the duration & intensity of your workouts may increase based on your
body’s tolerance to physical activity. When increasing physical activity, it is very
important to maintain a steady tempo throughout. The rate of work should be
sufficient enough to raise your heart beat into the target zone shown on the graph
below.
SIDE STRETCH OUTER THIGH
FORWARD
STRETCH
INNER THIGH
CALF / ACHILLES
Exercise Instructions
Physical activity during
this stage should last for
a minimum of 12 minutes,
although for most people,
it will take about 15-20
minutes for their heart
rate to reach the target
zone.

3. THE COOL-DOWN PHASE:
This stage is to let your cardio-vascular system and muscles wind down. Start by
reducing your tempo and continuing for approximately 5 minutes. The stretching
exercises (warm-up phase) should now be repeated. Again, remember not to force or
jerk your muscles into the stretch.
As you build your physical endurance, you may need to train longer and harder. It is
advisable to train at least three times a week, and if possible space your workouts
evenly throughout the week.
MUSCLE TONING:
To tone muscle while using the ASUNA Commercial Indoor Cycling Bike, you will
need to set the resistance level to high. This will increase the strain on leg muscles
which will then result in shorter training sessions. As the workload is increased, it will
decrease the time required for the muscles to obtain an adequate workout. If you’re
also trying to improve your fitness, you’ll need to alter your training program. You
should train normally during the warm up and cool down phases, but towards the end
of the exercise phase, the resistance should be increased in order to make your legs
work harder than normal. You may have to reduce your speed to keep your heart rate
in the target zone.
WEIGHT LOSS:
The most important factor here is the amount of effort you put in. The harder and
longer you work, the more calories you can burn. Please keep in mind that a healthy
calorie controlled diet should be paired with your workouts for best results.
Exercise Instructions

Included with your equipment is a set of SPD cleats compatible to the SPD pedals.
Your SPD pedals have a standard pedal with toe cage on one side, which allows you
to use regular shoes, as well as the SPD pedal on the other side. In order to use the
SPD pedal, you would have to own a pair of SPD shoes designed to fit the cleats.
Use the image below to see the proper order that the SPD hardware should be placed
in. Once combined, attach the cleats tightly into your shoes with the triangular
portion of the cleat towards the front of the shoe. Ensure the lateral center line of the
cleat is aligned to the ball of your foot and clip into the pedal. Cleat positions can be
turned and adjusted. To release the cleat from the pedal, simply lift and twist your
heel.
