3. Refer to the included parts diagram (if available in packaging) to verify all components are present and undamaged.

4.2 Assembly Steps (General)

1. Attach the front and rear stabilizers to the main frame using the provided bolts and washers.
2. Install the pedals onto the crank arms. Note that pedals are typically marked 'L' for left and 'R' for right, and the left pedal often tightens counter-clockwise.

4. Attach the handlebar post and handlebars, ensuring all cables (if any) are properly connected.
5. Install the computer monitor onto the handlebar assembly.

The computer monitor requires 2 AAA batteries (not included). Locate the battery compartment on the back of the monitor, insert the batteries according to polarity, and close the cover.

5. Operating Instructions

5.1 Unfolding the Bike

1. Place the folded bike on a stable surface.
2. Locate the locking pin or mechanism that secures the bike in its folded position.
3. Release the locking mechanism and carefully unfold the bike until it clicks into its fully extended, stable position. Ensure the frame is securely locked before use.

5.2 Adjusting the Seat

The seat height can be adjusted to accommodate different user heights. Loosen the adjustment knob located on the seat post, slide the seat to the desired height, and then firmly tighten the knob to secure the seat in place. Ensure your knees have a slight bend at the bottom of the pedal stroke.

5.3 Adjusting Resistance

The bike features a manual tension control knob, typically located below the handlebars. Turn the knob clockwise to increase resistance (making pedaling harder) and counter-clockwise to decrease resistance (making pedaling easier). There are 8 distinct resistance levels.

5.4 Using the Computer Monitor

The monitor automatically activates when you start pedaling. It displays the following metrics:

• TIME: Duration of your workout.
• SPEED: Current pedaling speed.
• DISTANCE: Distance covered during the current workout.
• CALORIES: Estimated calories burned.
• ODOMETER: Total accumulated distance.

Press the red button on the monitor to cycle through the display modes or to reset values (hold the button for a few seconds to reset most values, consult monitor specific instructions if available).

5.5 Securing Foot Straps

Place your feet on the pedals and adjust the straps to ensure your feet are securely held in place. This prevents slipping and provides a more efficient workout.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your Marcy NS-652 Exercise Bike.

• Cleaning: Wipe down the bike with a damp cloth after each use to remove sweat and dust. Avoid abrasive cleaners.
• Inspection: Periodically check all bolts, nuts, and moving parts for tightness and wear. Tighten any loose fasteners.

• Battery Replacement: Replace the monitor batteries (2 AAA) when the display becomes dim or stops functioning.
• Storage: When not in use, fold the bike and store it in a dry, cool place away from direct sunlight and moisture.

7. Troubleshooting

Here are solutions to common issues you might encounter:

• Monitor Not Displaying:
  • Check if batteries are correctly installed and not depleted. Replace if necessary.
  • Ensure all cable connections to the monitor are secure.
• Resistance Not Changing:
  • Verify the resistance cable is properly connected and not kinked.
  • Ensure the resistance knob is turning freely and engaging the mechanism.
• Clicking or Squeaking Noise:
  • Check all assembly bolts and nuts, especially around the pedals and frame joints, and tighten them.
  • Ensure pedals are securely tightened to the crank arms.
  • Apply a small amount of silicone lubricant to any pivot points if the noise persists.
• Bike Feels Unstable:
  • Ensure the bike is on a level surface.
  • Check that the folding mechanism is fully engaged and locked.
