1、Precautions for use
Please read the manual carefully before using the exercise bike. Ensure that you receive the
correct usage information. Including spare parts we provide you free of charge.
Warning! *When the exercise bike is not in use, please turn the brake ball head clockwise so
that the flywheel will not rotate
*Improper use or excessive use of the exercise bike may cause injury. It is suggested that
the user should pay attention to the use time and resistance when using the exercise bike for
the first time. The resistance can be adjusted appropriately first, and then the resistance can
be increased slowly after training for a period of time.
1. The exercise bike is a household fitness equipment, the maximum load-bearing capacity
is 120 kg.
2. Please operate in strict accordance with the instructions.
3. Please check the machine carefully before the first use, and check the machine strictly
according to the installation principle every 1-2 months after use. Please try to keep the
machine in normal use and use the original accessories.
4. If it cannot be used normally, please contact the dealer.
5. Please avoid contact with corrosive cleaning agents and other articles.
6. Please use it after correct installation and inspection.
7. Please adjust all adjustable parts to the maximum value before installation.
8. This product is adult fitness equipment . If it is used by children, please use it under the
supervision of the guardian. Children without supervision should stay away from the
equipment.
9. Please do not use this product to make dangerous actions.
10. Please use this product under the guidance of doctors and fitness professionals, it will
play a good role.
11. Please make a reasonable training plan before use and use this product strictly
according to the requirements.
12. The resistance of this product is adjustable. Please choose the right resistance.
13. Please check all knobs and screws carefully before use to ensure your safety.
14. The exercise bike is only suitable for one person at a time. Other people should keep a
safe distance of more than 50cm when using it.
15. When using, please adjust the height of handlebar and saddle reasonably. The height
of saddle is the reference height when the user sits on the saddle with his feet stretched out
and just completely touching the tread surface. It is recommended to adjust the handlebar
height to slightly higher than the saddle height.

~ 4 ~
16. When using, check whether the pedal of the bicycle is in good condition and whether the
fixing sleeve is in good condition. Put the foot in, fasten and fix it, and do not slide. At the
same time, the shoelaces must also be tied to avoid entanglement on the bicycle. If the feet
are not fixed well, coupled with the inertia of the flywheel, the feet are easy to step on empty,
causing danger.
17. Flywheel may cause danger. For example, when riding at high speed, it may bring
certain driving or impact to the legs;
After reaching a certain speed, stop the movement, do not try to stop the high-speed
flywheel with the strength of legs;
The brake should be used reasonably and the handbrake behind the handlebar should be
pressed by hand to avoid accidents. Wait until the flywheel stops.
When the flywheel rotates, it is forbidden to touch other parts of the body or other objects
with hands, so as to avoid danger.
18. Part 22 armrest fixed seat and 18 cushion tube are engraved with stop. Please do not
exceed this height when adjusting.
19. The exercise bike should be placed in a fixed and flat place, not in an inclined place to
prevent overturning.
2、Training Guide
The correct use of the exercise bike can make the buttocks and legs more healthy, increase
the oxygen in the blood volume, and make the spirit more relaxed. So how can we use the
right bike safely?
First: warm up in front of the exercise bike
Full warm-up exercise before exercise is indispensable, such as jogging, squatting, high
legs, leg pressing, pronunciation, waist twisting, arm movement. And so on the activity,
causes the body micro perspiration hot, generally in 5-10 minutes.
Second: adjust the height of the exercise bike seat and the front and back position and
handle height
To make the most of your exercise and ride as efficiently as possible, make sure your seat is
properly adjusted. It will also make you more comfortable.
1. Seat height adjustment: sit on the seat and put your foot on the pedal so that the toe ball is
above the pedal axis. When the pedal is at the lowest point, you should see the knee bend
slightly at an angle of 25-30 degrees. The pedal force in this position is maximum and most
comfortable. If the hips swing back and forth on the seat, the seat may be too high. In this
case, please lower the seat.
2. seat adjustment: sitting on the seat, when the distance between the two pedals and the
ground is the same, the front knee should not exceed the toe.

~ 5 ~
However, you can’t sit too far back, the angle between crus and instep should not be
more than 90 degrees.
3. Handle height adjustment: after adjusting the seat, adjust the handle to a slightly higher
height than the seat; keep the waist and back as straight as possible, especially for the
obese and the weak core. If not used properly, the lumbar spine may be injured.
4. The shoelace must be tied, and then put into the fixed sleeve of the foot, and fasten the
tension belt, which can let you put more on the pedal when you exercise. The muscles in
exercise are more effective in pedaling.
Third: the right posture of the exercise bike
Correct sitting posture: lean forward, arms straight, abdomen tight, abdominal breathing
method, legs parallel to the vehicle beam, knees, hip joint coordination, pay attention to the
rhythm of riding.
Correct trampling posture: correct pedaling should include: trampling, pulling, lifting and
pushing four coherent movements. The foot moves down first, then the calf retracts
backward, then raises upward, finally pushes forward, thus just completed a circle. Good
pedal rhythm not only saves physical energy consumption, but also improves speed.
Fourth: the right speed can be used for cycling
Frequency and intensity are the basic principles of exercise. At first, it is suggested that you
can find the right frequency, and then increase the amount of exercise. The average person
pedals about 60 to 80 times per minute. Warm up at low speed for each ride, and then
moderate and high frequency cycling for more than 20 minutes may cause slight sweating.
Fifthly, the purpose of different riding methods is different, but we should act according to our
ability. If you feel unwell, please stop training
1. In order to train to lose weight
For those who want to lose weight by bike, you can use aerobic cycling, which is to adjust
the feeling of resisting body load without exerting force. The intensity of this exercise should
be moderate, generally more than 30 minutes, in order to decompose fat. Therefore, the
best time to ride is 30 to 40 minutes, with a heart rate of 100-110 beats / min.
2. In order to train muscles
Exercise by bike to build muscles. Choose easy resistance, slow warm-up for 5 minutes,
then as a high-speed ride for about 5 minutes with a heart rate of 170-180 beats / min, and
then gradually slow down for 5-10 minutes so that the heart rate returns to 100 beats / min or
less. As a group, you can even do several groups and arrange a 3-5 minute rest between
groups.
