The belt tension of this product has been adjusted in advance in the factory. Long-term high-strength use will
cause the belt to lengthen and become loose, resulting in instantaneous slip when force is applied. In case of this
situation, the screw of fixed inertia wheel can be loosened at the same time, so that the hexagon screw can be
slightly locked and adjusted with a wrench. However, the above wrench used for calibration is not in the box
attached with the machine.

How to adjust the resistance and emergency stop of the exercise bike:

     Considering the needs of different users, this product is equipped with resistance adjustment system and the
user can adjust the resistance by adjusting the knob. (+. -) is marked on the trim, where + indicates an increase in
resistance and - indicates a decrease in resistance. According to the requirements of the movement, the user can
increase the resistance by clockwise rotation, reduce the resistance by counterclockwise rotation and press the
knob down hard to stop the emergency. 

(note: please make sure that the brake system is in an effective state

before each use).

How to adjust the four uneven feet of the exercise bike:

This product is equipped with 4 adjustable foot pads under the front and rear bottom pipes. If it is found that the
front and rear feet of the product are uneven, you can adjust them through the four adjusting pads, so that the
product can be used in a stable state.

Sit on a clean cushion with one leg straight, put the other leg inward to make it
close to the inside of the straightened leg amd try to touch your toes with your
hands. Hold for 10 to 15 seconds and then relax. Repeat 3 times for each leg
(see Figure 2).

3) Stretch calf and heel tendon

Stand with both hands on the wall and one foot behind. Keep your hind legs
upright with your heels on the ground and tilt toward the wall. Hold for 10 to 15
seconds and then relax. Repeat 3 times for each leg (see Figure 3).

4) Stretch quadriceps

Common problem handling

Warm-up representation

    Warm up before exercise can help blood circulation, ensure the normal
activity of muscles, and reduce the cramps and strains caused by strenuous
exercise. Therefore, it is necessary to take 5 to 10 minutes to do the following
stretching exercises. Do each stretch about 30 times, but do not stretch your
muscles too hard. Stop when you feel a little pain in the stretching area and do it
again after the exercise.

1) Stretch down

Bend your knees slightly, bend your body forward, relax your back and
shoulders, and try to touch your toes with both hands. Hold for 10 to 15 seconds
and then relax. Repeat 3 times (see Figure 1).
