CauTion

Risk of accident and injury!

correctly.
The optimal sitting position depends on the frame size of the bicy
-
cle, the physical size of the rider and the settings of the handlebars
and the seat. Specialist knowledge is required to adjust the bicycle
to an optimal sitting position.
The optimal sitting position can also depend on the use of the
bicycle, e.g. if it is predominantly used for sports.
The key features of an optimal sitting position are:
–
If a pedal is at the top, the knee angle of the upper leg and
the arm angle is 90°. The lower leg must be slightly bent (see
Fig.
“Characteristics of an appropriate seating position”
, left).
–
When one pedal is forwards, the knee must be above the axle
of the front pedal (see Fig.
“Characteristics of an appropriate
seating position”
, right).
–
The arms are relaxed and slightly bent outwards (not shown
in the picture below).
–
The back is not perpendicular to the seat post.
