Instructions on Product Usage

Illustration diagram of foot pad adjustment

Descriptions: If the overall balance of the bike is not good, users can adjust it through the 4 foot pads of the front and rear foot tubes. Rotating the foot pads can make them fully support the ground, and the bike will no longer wag from side to side.

[Diagram showing the rear of the exercise bike with an inset showing a foot pad being rotated to adjust height, labeled 'High' and 'Low'.]

Battery Installation and Indicator Status Tips

Battery installation: Open the battery cover on the back of the bike, install the battery (for test), and put the battery cover back.

Battery replacement: If the Bluetooth has no signal or cannot be connected, please rotate the pedal and observe the Bluetooth indicator. If the indicator doesn't flash for more than 60s, please replace the battery in time.

[Diagram showing battery compartment and batteries.]

Note: After using the test battery once, replace it with a new battery.

Indicator status description:

• The indicator light goes off: The Bluetooth is dormant or out of power.
• The indicator light slowly flashes: When the Bluetooth is in the stand-by state, it can be connected to the bike (step on the bike pedal for two cycles to enter this state).
• The indicator light quickly flashes: The Bluetooth is in the connection status. The Bluetooth and APP will be disconnected automatically after suspending the movement for 1 minute.

[Diagram showing the location of the Bluetooth indicator light on the bike.]

Illustration Diagram of Cushion Adjustment

Properly set the cushion position

• Cushion height: Align your legs, and stand straight next to the cushion. Adjust the cushion, align it with your hips (Figure A), and then sit on the cushion. Step on the pedal with your heels, stop when your feet are directly under you, and keep your legs completely straight (Figure B).
• Front and rear position of the cushion: Place your right shoe into the pedal and the foot straps of the pedal. When the current pedal is in the short needle position at 3 o'clock (level with the ground), if the front of the knee joint is in the vertical line with the pedal, the adjustment is correct (Figure C).

[Diagrams A, B, and C illustrating correct cushion height and front/rear positioning relative to the pedal and knee joint.]

The right crank is parallel to the ground on the right, that is the short needle direction at 3 o'clock.

Adjustment method of cushion

• Up and down adjustment method: Turn the cushion column knob with one hand, loosen it slightly and pull outward. Grab the cushion with the other hand, and pull it up (or down). Slightly move the saddle column up and down after adjusting to the desired position, loosen the spring to restore it to its original position (the knob is already in the hold of the cushion column when you hear a "clicking" sound), and then re-tighten the knob.
• Front and rear adjustment method: Loosen the knob at the bottom of the saddle and slide the saddle back and forth. Tighten the knob after adjusting to the desired position.

[Diagrams showing the adjustment mechanism for seat height and fore/aft position.]

Illustration Diagram of Handrail Adjustment

Correctly set the handrail height

You can set the handles to the appropriate height according to your height and riding experience.

• The method recommended by our company:
• For first training people: Adjust the handrail slightly higher than the cushion.
• For experienced people: Adjust the handrail to the same height as the cushion, or just below it.

[Diagrams showing recommended handrail heights for beginners and experienced users.]

* If you feel worried about lumbar disc herniation or spondylolysis, please consult your doctor before use. In addition, it is recommended to adjust the handrail to a higher position than beginners.

Adjustment of handrail height

You can adjust the handrail height according to your height. Rotate the pull pin, loosen it and put it outward to move the handrail column up and down (Figure A). After adjusting to the appropriate height, please align the pull pin and the hole of the handrail column, and tighten it by turning clockwise (Figure B).

[Diagrams Figure A and Figure B illustrating the process of adjusting the handrail height using a pull pin.]

* If the handle lever cannot be moved up and down smoothly, you can apply lubricating oil. Please note that your hands may get dirty if you touch them directly.

Resistance Adjustment and Handling Instructions

Resistance adjustment and use method of brakes

• Resistance adjustment: Rotate the resistance adjusting knob clockwise to increase resistance (A) and counterclockwise to reduce resistance (B). Please adjust the resistance according to your physical strength.
• How to use brakes: In case that you want to stop after reaching a certain movement speed, you can put your hand on the knob and push it down to gradually add resistance to the wheels and finally stop the bike.

[Diagram showing the resistance knob labeled A and the brake function labeled B.]

Machine handling instructions

When moving the product, hold the front of the handle and push it down so that the moving wheels of the forefoot tube completely touch the ground. For women and the elderly, it is easier to hold the front leg tube with your feet and press down on the front of the steering wheel. After lifting up, the movement becomes simple. The method is the same when putting it down; first, fix the front leg tube with your feet before putting it down.

Warm-up

Do stretches before exercising. Warm muscles are easier to stretch, so start with a 5-10 minute warm-up, then do some stretches shown below - 5 times, 10 seconds or more per leg. Do it again after the workout.

1. Stretch down: Bend your knees slightly, slowly bend your body forward, relax your back and shoulders, and try to touch your toes with your hands. Hold for 10-15 seconds, then relax. Repeat 3 times. [Figure 1: Person bending forward from the waist, reaching towards toes.]
2. Seated hamstring stretch: Sit with one leg straight. Bring the other leg in so that it is snug on the inside of the straightened leg. Try to touch your feet with your hand's toe. Hold for 10-15 seconds, then relax. Repeat 3 times for each leg. [Figure 2: Person sitting with one leg extended and the other bent, reaching for the toes of the extended leg.]
3. Calf and Achilles tendon stretch: Stand with both hands against the wall or a tree, put one foot behind another. Keep the back leg straight and your heel on the ground, lean toward a wall or a tree. Hold for 10-15 seconds, then relax. Repeat 3 times for each leg. [Figure 3: Person standing, leaning forward against a wall, with one leg extended back.]
4. Quadriceps stretch: Reach back with your right hand, grab your right foot and slowly pull it toward your hips until you feel the muscles in the front of your thigh tense. Hold for 10-15 seconds, then relax. Repeat 3 times for each leg. [Figure 4: Person standing, bending one knee and pulling the foot towards the hip with the hand.]
