Mountain bike
The frame geometries for mountain bikes differ
depending on the type and area of use. The frame
size is not dependent on the wheel size. The
differences are already taken into account in the
recommended frame sizes.

Table 13: Recommended frame size for mountain bikes
Racing bicycles and gravel bikes
The different frame heights are closer together on
racing bicycles and gravel bikes. Smaller
increments in the frame heights ensure precise
adjustment to the rider's height.
The seat on the pedelec is largely determined by
the length of the top tube:
• The shorter the top tube is, the steeper the sitting
position is.
• The longer the top tube is, the more stretched-out
the sitting position is.

Bicycle for young adults
A person grows in height rapidly during
adolescence. As a result, the frame size needs to
be checked every six months.

Child's bike
Children are growing constantly. As a result, the
frame size needs to be checked every six months.
It is important that riders, especially learners, can
safely put both feet on the ground. Children thus
need a pedelec that is appropriate for their height.
This is the only way to ensure a safe ride.
