Operating Instructions
Adjusting Seat Height
The seat height can be adjusted to five different levels to accommodate various user heights. Loosen the adjustment knob located on the seat post, slide the seat to the desired height, and then tighten the knob securely. Ensure your knees have a slight bend at the bottom of the pedal stroke.

Adjusting Resistance
The bike features 8 levels of magnetic resistance. Turn the resistance knob, located below the LCD monitor, clockwise to increase resistance and counter-clockwise to decrease it. Start with a lower resistance and gradually increase as your fitness improves.
