Seat cushion
The standard seat cushion consists of a 1,4 cm
thick layer of flexible EVA foam.This is a black
material with closed cells that is also used in
the production of high quality camping mats. It
feels very comfortable without appearing too
soft or spongy. It is waterproof so that you can
dry your seat with a sweep of your hand in ca-
se your bicycle has become wet.
For better ventilation, an airflow cushion is
available as accessory.This cushion consists of
several layers:A soft foam and a rigid mesh,
which provides for an approximately 1 cm
thick air cushion with excellent circulation.
These two layers are wrapped up in a cover
that consists of fine mesh like it is known from
high quality Rucksacks.
You can wash the material at 30° Celcius and
it dries very quickly. In case you want to wash
the seat cushion take it off the seat.Then open
the Velcro at the back and take out the foam
cushion and the airflow insert.
The seat cushion suffers from wear through
constant use.At the parts that are under punc-
tual strain the mesh can be pressed together
permanently. In order to provide a good riding
comfort in that situation the airflow cushion
has additional foam padding.
Seat Cushion
Caution! The seat cushion is fastened with
Velcro and you can take it off. For this pur-
pose it is important not to simply grab the
foam and take it off since the Velcro could
come off. In order to take off the seat cus-
hion lift up the upper part a little bit from
the seat.Then you grab the cushion on both
sides together with the end of the Velcro
that sticks out slightly and remove the cus-
hion slowly. In case the Velcro comes off
fasten it again with a good glue.
Caution! Never expose the seat cushion to
extreme heat or focused sunlight.The mate-
rial warms up considerably.The heat may
melt the glue of the Velcro.The seat cushion
can be damaged when the rays of the sun
are bundled through a lens.Take care to ne-
ver leave any bubble wrap on the seat in the
sun.The air bubbles in the film act like a
burning glass and shrink the seat cushion.
