Your Street Machine Gte is equipped either
with the ErgoMesh
®
mesh seat or the ad-
justable BodyLink
®
seat from HP V
ELOTECHNIK
.
The following instructions refer to the
BodyLink seat. Length, seat back angle and
lower seat angle are adjustable for this seat.
The adjustment of the seat length and the
proper seat angle is crucial for a comfortable
feeling while riding your recumbent.
The upper curve of the seat back in the area
of the shoulder blades determines the correct
seat length:Through this shape the shoulder
and neck area is lifted from the recumbent po-
sition so that the head rests in a natural and
relaxed position. For this reason you shouldn't
need a head rest if you have the right seat po-
sition. On long rides, a head rest can increase
your riding comfort as you can relax your
neck for a few seconds by leaning back.You
can mount our custom headrest to your exist-
ing seat.
The seat is too small when you have the im-
pression that your back is pressed too much
into a "hunchback". It is too large when you
have the impression that the seat angle is too
far back when you are in the most upright po-
sition, or when you hit the upper seat edge
with the back of your head when you look up-
wards.
Adjusting the seat length
Take off the seat cover (see page 49). Open
the quick release lever for the seat back angle
adjustment, so that the seat is not bent with
inner tension. Loosen the 4 screws at the in-
ner side of the seat back with an allen key
SW4 a few turns. Step behind your bike and
hold the seat back with both hands. Pull or
push the seat back to achieve the preferred
seat length.To achieve the smallest possible
seat length, move the 2 upper screws from the
top to the middle holes.
Tighten all 4 screws with 5–6 Nm. Move the
seat back rest to the preferred angle and close
the quick release lever firmly. Reinstall the seat
cover
Length adjustment of the Airflow cushion
The optional Airflow-cushion consits of two
parts, that connect in a V-type shape. Loosen
the velcro mount of the upper part, and place
it in the desired position, than fasten the vel-
cro.
Adjusting the seat back angle
A big advantage of the BodyLink
®
seat on your
recumbent is that you can adjust the seat back
angle very quickly. For beginners or rides in
the city you can choose an upright seat posi-
tion for a better view, and for longer rides you
can choose a flat position for better aerody-
namics.
The seat back is fastened with a quick release
lever on a slotted aluminum seat mount.You
can adjust the seat back angle by 10 degrees
by simply opening the quick release lever. In
the medium seat position the angle is about
35° from horizontal.
Caution!
Do not loosen or tighten the 4
screws in the lower seat part to adjust the
seat length. Maximum tightening torque of
these screws is 3–4 Nm.
Caution!
To avoid noise from the seat when
loaded, the contact surfaces between the
two seat halfs need to be seperated by self-
adhesive plastic sheets and all contact sur-
faces of seat and seat mounts and frame
need to be lubricated with grease.
