HOW TO USE THE EXERCISE BIKE
HOW TO ADJUST THE HEIGHT OF THE SEAT
For effective exercise, the seat should be at the proper
height. As you pedal, there should be a slight bend in
your knees when the pedals are in the lowest position.
To adjust the height
of the seat, first
loosen the post
knob a few turns.
Next, pull the post
knob outward,
slide the seat post
upward or down-
ward to the desired
position, and then
release the post
knob into one of the adjustment holes in the seat post.
Move the seat post upward or downward slightly to
make sure that the post knob is engaged in one of
the adjustment holes in the seat post. Then, tighten
the post knob.
HOW TO ADJUST THE HORIZONTAL POSITION OF
THE SEAT
To adjust the hori-
zontal position of
the seat, first loosen
the carriage knob
a few turns. Then,
move the seat for-
ward or backward to
the desired position,

Questions and answers
Belt broke is it worth replacing ?
The manual provides instructions for adjusting the drive belt on the Pro-Form 831.21813.2 but does not mention replacing it. However, since the bike is covered by a 90-day full warranty and the frame has a 5-year warranty, it may be worth checking if the repair is covered. If the bike is out of warranty, replacing the belt could be worth it if the rest of the bike is in good condition and the cost of replacement is reasonable compared to buying a new bike.
