OPERATIONS

What to Wear

Wear rubber-soled athletic shoes. You will need the appropriate clothes for exercise that allow you to move freely.

How Often Should You Exercise

 Consult a physician before you start an exercise program. Stop exercising if you feel pain or tightness in your chest, 

become short of breath, or feel faint. Contact your doctor before you use the machine again. Use the values calcu-

lated or measured by the machine’s computer for reference purposes only. The heart rate displayed on the console 

is an approximation and should be used for reference only.

•  3 times a week for 30 minutes each day.
•  Schedule workouts in advance and try to follow the schedule.

Seat Adjustment

Correct seat placement encourages exercise efficiency and comfort, while reducing the risk of 

injury.
1. With a Pedal in the forward position, center the ball of your foot over the center of it. Your leg 

should be bent slightly at the knee.

2. If your leg is too straight or your foot cannot touch the Pedal, move the seat down on the upright 

bike. If your leg is bent too much, move the seat up.

!

Step off the bike before you adjust the seat.

Loosen and pull the adjustment knob on the seat tube. Adjust the seat to the desired height. 

Release the adjustment knob to engage the locking pin. Be sure that the pin is fully engaged and 

fully tighten the knob.  

!

Do not set the Seat Post position higher than the stop mark (STOP) on the tube.

To move the seat closer to, or away from the console, loosen the seat slider adjustment knob. Slide 

the seat forward or rearward to the desired position and tighten the knob.

Foot Position / Pedal Strap Adjustment

Foot pedals with straps provide secure footing to the exercise bike.
1. Put the ball of each foot on the Pedals.
2. Rotate the Pedals until one can be reached.
3. Fasten the strap over the shoe.
4. Repeat for the other foot.
Be sure toes and knees point directly forward to ensure maximum Pedal efficiency. Pedal straps 

can be left in position for subsequent workouts.

Power-Up / Idle Mode

The Console will enter Power-Up / Idle Mode if it is plugged into a power source, any button is 

pushed, or if it receives a signal from the RPM sensor as a result of pedaling the machine.

Auto Shut-Off (Sleep Mode)

If the Console does not receive any input in approximately 5 minutes, it will automatically shut off. The LCD display is off 

while in Sleep Mode.

 Note: 

The Console does not have an On/Off switch.

Initial Setup 

During the first power-up, the Console should be setup with the date, time and your preferred measurement units. 
1.   Date: Push the Increase/Decrease buttons to adjust the currently active value (flashing). Push the Left/Right buttons 

to change which segment is the currently active value (month / day / year). 

2.   Push OK to set.
