1 Safety
Seat Height and Handlebar Reach
WARNING!
Improperly adjusted seat height could affect the rider's ability
to reach the handlebar and pedals may result in an unexpected
movement, loss of control, and serious injury or death. Follow
these guidelines when adjusting the seat height. Always
ensure the seat post minimum insertion marks are below the
seat clamp and cannot be seen. Ensure the seat clamp is
locked and the seat cannot move.
❶ Your legs should be almost completely straight when the
pedal is in the down most position, just a slight bend in
the knee. Figure 1.2
Note: The rider's feet may not touch the ground easily. If
this is the case the rider can simply move forward off the
seat to mount and dismount the bicycle or the seat can be
adjusted lower if the rider is uncomfortable with the height,
but note that riding is more difficult with the seat too low,
as the legs are in an unnatural position.
Do not raise the seat so much the knees lock straight when
pedaling or you have to move forward off the seat to pedal.
This is unsafe and the bicycle cannot be controlled in this
condition.
❷ You should be able to safely reach the handlebar with
your arms bent slightly (approximately 10 degrees) at
the elbow.
