Getting Comfortable
Setting Your
Weight
Seat
Adjustment
The body weight setting does
not affect the calorie expenditure
calculation. Unlike treadmills or
other weight-bearing exercises,
calories burned during exercise
biking does not change with
different body weights.
Adjust the seat so that
when your leg is fully
extended with your
feet in the pedals, your
knee is slightly bent.
While standing next to the bike, pull out the
seat adjust knob and lower the seat to the
lowest position. Next, get onto the bike with
one leg fully extended in a pedal, supporting
most of your weight. Grasp the horn of the
seat and pull it up under you to a snug fit,
letting the ratcheting mechanism lock the
knob and pin in place.

Variations in human
exercise efficiency are another
potential source of error,
with differences of plus or
minus 10% common in the
population.
