To adjust the angle of the back rest only open
the front quick release lever.That way the seat
stays fixed on the rail and you keep the adjust-
ment made for the leg length. Only when the
back quick release lever is closed very tightly
it is better to open it a little bit, too.
The rear rack moves together with the seat
back.Take care to keep your fingers, bags,
straps, etc. away from the area between inte-
grated rear rack and frame while adjusting the
seat back.
Hold the seat at the upper end of the back
rest and move it to the correct angle.
Close the quick release levers.

Adjusting the seat angle
You can adjust the seat back in a range of
55° - 65°.
The angle you feel comfortable with depends
on the form and the length of your back.
The back seat back has an ergonomic shape
according to the S-form of the spine.The up-
per bend automatically puts the neck in an
upright position so that you don't feel any
strain in neck and shoulders even on a long ri-
de.
In addition to this you can influence the shape
of the back rest by adjusting the tension of the
inlaying belts.
To get started we recommend a medium seat
angle.After you have gained some riding expe-
rience you can start trying different angles.
Recumbent beginners often start with a very
upright seat position.That way the biggest part
of your weight lies on the seat cushion and
you mainly sit on your muscles which can lead
to problems on a long ride.
The lower the angle the better you distribute
your weight between seat cushion and seat
back - this is one of the main advantages of
the recumbent.
Another advantage of a low seat back angle is
better aerodynamics. In a recumbent position
you don't offer much area for head wind
which can result in a big plus in velocity.
Adjusting the seat
Caution! The two quick releases have to be
tightened firmly (tightening force 15–20 kgs.
/ 45 lbs.) after adjusting the seat.You must
not open them while riding.After they have
been closed the imprint "close" must be visi-
ble. If the quick releases are not tightened
appropriately the seat can move while riding
and you may no more be able to control
your bicycle.
