5. Operating Instructions
5.1 Adjusting Seat Position
The seat height can be adjusted to 4 different sections. Loosen the adjustment knob, slide the seat post to the desired height, and re-tighten the knob securely. Ensure your knees have a slight bend at the bottom of the pedal stroke.
5.2 Selecting Exercise Mode (3-in-1 Functionality)
This bike offers three exercise modes:
- Upright Mode: Provides a high-intensity workout.
- Recumbent Mode: Offers a less strenuous workout with back support.
- Semi-Recumbent Mode: A hybrid position for varied comfort and intensity.
To switch between modes, adjust the frame angle using the designated knob or lever (refer to specific frame adjustment points on your bike). Ensure the frame is locked securely in place before use.

5.3 Adjusting Magnetic Resistance
The exercise bike features 8 levels of adjustable magnetic resistance. Turn the tension control knob, located below the console, clockwise to increase resistance for a more challenging workout, and counter-clockwise to decrease resistance for an easier workout or warm-up.
5.4 Using the LCD Display Console
The digital LCD monitor displays the following fitness data:
- Time: Duration of your workout.
- Speed: Current cycling speed.
- Distance: Total distance cycled.
- Calories: Estimated calories burned.
- Pulse: Your heart rate, measured by the hand pulse grips.
To measure your heart rate, place both hands firmly on the pulse grips located on the handlebars. The console will display your pulse after a few seconds.
The console also includes a phone/tablet holder for convenience during your workout.
5.5 Utilizing Arm Resistance Bands
The integrated arm resistance bands allow for upper body exercises while cycling. Hold the handles and perform various arm movements (e.g., curls, rows) to engage different muscle groups. This provides a balanced full-body workout.
6. Maintenance
- Cleaning: Wipe down the exercise bike with a damp cloth after each use to remove sweat and dust. Avoid abrasive cleaners.
- Inspection: Regularly check all bolts, nuts, and moving parts for tightness and wear. Tighten any loose fasteners.
- Lubrication: The magnetic resistance system is generally maintenance-free. Do not lubricate internal components unless specifically instructed by customer support.
- Storage: When not in use, fold the exercise bike to minimize space. Store it in a dry, cool place away from direct sunlight and moisture. The integrated wheels allow for easy movement.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on console | Batteries are dead or incorrectly installed. | Replace batteries or ensure they are inserted with correct polarity. Check wire connections. |
| Inaccurate pulse reading | Hands not firmly on grips; dry hands; loose connection. | Ensure firm contact with both pulse grips. Moisten hands slightly if too dry. Check sensor wire connections. |
| Squeaking or grinding noise | Loose bolts; friction from moving parts; internal issue. | Check and tighten all assembly bolts. Ensure pedals are securely fastened. If noise persists, contact customer support. |
| Resistance not changing | Resistance cable disconnected or damaged; internal mechanism issue. | Check the connection of the resistance cable to the tension knob and the internal mechanism. Contact customer support if the issue persists. |
| Bike feels unstable | Not on a flat surface; stabilizers not level; loose frame bolts. | Move the bike to a flat surface. Adjust the leveling caps on the stabilizers if present. Tighten all frame bolts. |
