HOW TO OPERATE THE EXERCISE CYCLE
HOW TO ADJUST THE SEAT
For effective exercise, the seat should be in the proper
position. As you pedal, there should be a slight bend in
your knees when the pedals are all of the way forward.
To adjust the seat, push the seat lever down, slide the
seat forward or backward, and then firmly pull the seat
lever back up.
HOW TO ADJUST THE UPRIGHT
The upright can be
adjusted to the
height that is the
most comfortable for
you. To adjust the
upright, first turn the
indicated knob
counterclockwise
two or three turns to
loosen it (if the knob
is not loosened
enough, it may
scratch the upright).
Next, pull the knob,
slide the upright to the desired height, and then release
the knob. Move the upright up and down slightly
until the pin on the knob snaps into one of the
holes in the upright. Then, turn the knob clockwise
until it is tight.
HOW TO ADJUST THE PEDAL STRAPS
To adjust the pedal
straps, first pull the
ends of the straps
off the tabs on the
pedals. Adjust the
straps to the
desired position,
and then press the
ends of the straps
back onto the tabs.
