IMPORTANT SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS BEFORE USING THIS EXERCISE EQUIPENT
1. Use this equipment only for its intended use as described in this manual. Do not attempt
to ride this bike at high pedal speeds until you have ridden the bike for some time and
are comfortable riding at slower pedal speeds.
2. The bike is NOT equipped with a freewheel system which means that when the flywheel
is in motion, the pedals will be in motion. Do not attempt to stop the unit by applying
backward pressure to pedals while they are turning as knee injury may occur. Do not
attempt to remove your feet from pedals while they are moving.
3. Wait for flywheel to coast to a stop before dismounting the bike. If you want to stop the
flywheel, push down on the brake knob.
4. Serious injury or death may occur from over-training. Consult a medical doctor or
qualified fitness instructor to determine an exercise program appropriate for your level
of fitness.
5. Do not attempt to turn the pedal cranks by hand. Do not touch any driving mechanism
while it is in motion as possible injury could occur.
6. In a home setting, keep children away from the bike when it is not in use. Keep children
and pets away from the unit while it is in use.
7. Do not attempt to perform dip movements on handlebars.
8. Never drop or insert any object into any opening of the bike.
9. Only use the bike on a stable, level floor.
10. Follow instructions for safe use of the equipment including proper seat position,
handlebar position, and use of foot positioning system of pedals. Do not attempt to pull
up handlebar post and seat post over the ‘MAX.’ graduation.
11. For safe operation, allow for at least 1foot (30cm) of free space to either side of the unit
and 2 feet (60cm) of free space to the rear of the unit.
Regularly examine the bike for damage and wear. Inoperable components should be replaced
immediately or the equipment should not be used until it is repaired.
Failure to follow all guidelines may compromise the effectiveness of the exercise experience,
expose yourself (and possibly others) to injury, and reduce the longevity of the equipment.

GUIDELINES FOR SAFE OPERATION
WARNING!
AS THE OWNER OF THIS EXERCISE EQUIPMENT, YOU SHOULD INSIST THAT ALL
USERS FOLLOW THE SAME GUIDELINES: YOU SHOULD MAKE THIS MANUAL
AVAILABLE TO ALL USERS.
1. Obtain a complete physical examination from your medical doctor and enlist a
health/fitness professional’s aid in developing an exercise program suitable for your
current health status.
2. When working out for the first time, start out slowly for a minimum of five minutes. After
your muscles are warmed up, gradually increase the pedaling rate zone.
3. The speed and duration of your exercise program should always be subject to how you
feel. Never permit peer pressure to exceed your personal judgment while exercising.
4. Overweight or severely de-conditioned individuals should be particularly cautious when
using the equipment for the first time. Even thought such individuals may not have
histories of serious physical problems, they may perceive the exercise to be far less
intense than it really is, resulting in the possibility of overexertion or injury.
5. Proper installation and regular maintenance are required to ensure user’s safety.
Maintenance is the sole responsibility of the owner.

ADJUSTING THE BIKE FOR A PROPER FIT
Take some time to learn how to properly adjust the bike to your body; it will make your workouts
more pleasant and a safer experience too. Riding the bike when it is incorrectly adjusted can result
in discomfort and increase your risk of injury.
Adjustment of Seat Position:
Seat Height Adjustment
1. Standing next to the bike, adjust seat until it is about hip height.
2. Rotate crank arms until the pedals are in the vertical position: 12 and 6
o’clock.
3. Place your foot in toe cage of pedal closest to the floor and mount the
bike. Ensure that the ball of your foot is over the center of pedal. Your leg
should be slightly bent at the knee, about 5 degrees.
4. If your leg is too straight or your foot cannot touch pedal you will need to
lower seat height. If your leg is bent too much you will need to raise seat
height.
5. Dismount the bike. Loosen the quick release lever on seat post and adjust up or down as
necessary.
6. When seat is in the desired position, tighten the quick release to secure the seat post.
7. Note the final position mark on the seat post for future reference.
Seat Forward/Aft Adjustment
1. Sit on bike with crank arms in the 3 and 9 o’clock positions. For road bike
training, a proper forward/aft position of the seat is achieved when small
bump at the top of the shin is above pedal axle.
2. Dismount the bike. Loosen the quick release under the seat and slide the
seat forward or backward as desired; then tighten the quick release.
Handlebar Adjustment:
Handlebar Height Adjustment
1. The Handlebar height is a matter of preference. Start with a handlebar height that is the same
as the seat’s height. Adjusting the handlebar higher will give the rider a more upright position;
lower will result in a more crouched position.
2. Raise or lower the handlebar by loosening quick release on handlebar
post and adjust by sliding the handlebar mount up or down as desired.
Then tighten the quick release to secure the handlebar post. Note the
final position mark on handlebar post for future reference.
Adjustment of Handlebar’s Forward/Aft Position
1. Loosen the quick release under the handlebar and slide the handlebar
forward or backward as desired. Suitable forward/aft position should allow the rider to
comfortably grasp the handlebar with a slight bend at the elbow.
2. Tighten the quick release to secure the handlebar assembly.

HOW TO USE OUR DUAL FUNCTION PEDAL:
Attaching Cleats to Your Shoes
If you have questions it is recommended that you consult a bicycle dealer for assistance, and
also refer to your shoe manufacturer’s instructions.
When fixing the cleat the lateral center line should be under the center of the ball of the foot.
Adjust forward and backward via the slots in the shoe sole. Adjust laterally via play between cleat
washer and cleat. Tighten cleats very firmly. Cleat position can be fine-tuned, according to
personal preference, after trial use. It may take time to find your optimum cleat set-up.
Toe Clips
All standard toe clips can be attached to the pedals. Use fixing hardware and installation
instructions supplied with toe clips and ensure the attachment screws are firmly tightened before
use.
To Use Pedals
Engage cleated shoes in pedals by placing cleat between bindings while pushing down.
Disengage by twisting heel outwards away from exercise bike.
Binding tension is adjustable and should be set so that cleat and shoe do not disengage when
pedaling. Use an Allen key to turn tension adjusting screws, clockwise to increase binding tension,
counterclockwise to decrease binding tension.
Use the opposite side of the pedal from the clip-in side when wearing regular sports training
shoes. The regular side can be used with or without toe clips.

BASIC OPERATION
Now that you have established a proper riding position, take a few minutes to ride the bike and
determine that your position is comfortable. Start pedaling at a slow pace with your toes and
knees pointed directly forward. Hold the handlebar lightly and in a position that allows your
shoulders and upper body to relax. Pedal easily, at a low resistance until you feel confident that
you could ride in that position for the duration of your workout.
WARNING!
IF AT ANY TIME DURING YOUR WORKOUT, YOU FEEL CHEST PAIN, EXPERIENCE SEVERE
MUSCULAR DISCOMFORT, FEEL FAINT, OR ARE SHORT OF BREATH, STOP EXERCISING AT
ONCE. IF THE CONDITION PERSISTS, YOU SHOULD CONSULT YOUR MEDICAL DOCTOR
IMMEDIATELY.
1. Pedaling resistance is controlled by the tension knob. Resistance can be changed at any
time by turning tension knob: clock-wise for more resistance; counterclockwise for less
resistance.
2. To apply the brake, press down on the tension knob.
3. Before dismounting, apply the brake to stop flywheel, or increase resistance and let
flywheel come to a stop.
