Seat height
In order to obtain the most comfortable riding position
and offer the best possible pedalling efficiency, the seat
height should be set correctly in relation to the rider's
leg length. The correct seat height should not allow
leg strain from over-extension, and the hips should not
rock from side to side when pedalling.
While sitting on the bicycle with one pedal at its lowest
point, place the ball of your foot on the pedal. The
correct seat height will allow the knee to be slightly
bent in this position.
Arm reach
To obtain maximum comfort, the rider should not over
extend his or her reach when riding. There should be a
slight bend in the rider's elbows. Refer to the Assembly
section to learn how to adjust the seat height and arm
reach.
WARNING: The seat's "minimum insertion"
mark should not be visible when the seat is
inserted into the seat mast of the bicycle. Do
not raise the seat beyond this mark. The seat
post or frame may break causing you to lose
control and fall. Always check and make sure
that the seat post clamp is tightened securely
before riding.
