Alignment of the handlebars to the wheel
To align the handlebars perpendicular to the
front wheel, turn the adaptor for indirect
steering clamped into the bottom end of the
fork steerer tube.
Loosen the allen key bolt a few turns. Hold the
front wheel and align the handlebar perpendi-
cular to the front wheel. Push the adaptor fully
into the fork steerer tube, so that the metal
plate welded onto the tube is positioned di-
rectly at the end of the fork steerer tube.
Tighten the allen bolt with 30–32 Nm.

The friction adjustment should not need fre-
quent readjustment in normal use. Sometimes,
rain will cause the friction to drop slightly, but
things should go back to normal when dried out.
Adjusting the under seat steering
handlebars
Your GrassHopper with under seat steering is
equipped with an „indirect“ steering.The han-
dlebars are supported by a stem that pivots in
the frame.The front fork is connected with a
steerer rod to the stem.
Horizontal alignment of the handlebars
The stem is made of two parts that telescopi-
cally slide into each other.The connection is
made with an quick release lever clamping.
Open the lever while pushing the security but-
ton on the lever. Sit on the bike and align the
handlebars horizontally, so that both bar ends
are at same height. Close the quick release
lever untill the security button locks in. Check
the safe clamping by trying to turn the handle-
bars in the stem.This should only be possible
with high forces. If the clamping is to loose,
open the quick release lever and adjust the
counter nut of the QR.The ability to turn is
designed on purpose: In case the bike drops
over the handlebars can turn without being
bent or broken immediately.
We suggest to fully insert the stem half. If you
move the handlebars further back, you will in-
crease your turning circle as the handlebar
with contact the frame or lowrider earlier.
Adjusting the handlebars
Danger!
Do not loosen the bolt past the
minimum friction point. If you do, retighten
the bolt until you can feel the friction in-
crease.The bolt must be secured with Loctite.
Danger!
The minimum insertion depth of
the stem half is 5 cm (2"). In no case may
the rear end of the inserted stem half be-
come visible in the clamping slot.
Caution!
On the left side of the handlebars
there is a foam liner to protect the paint
where the handlebar touches the frame.
Check that it is in the correct position and
replace it when worn or lost.
Danger!
This tightening torque is mandato-
ry! If you do tighten the bolt with a wrong
torque, the adaptor could turn or bolt could
break while riding, leading to a crash. Only
use our original bolt of the strength type
12.9.The bolt head and threads must be lu-
bricated. Do not use a washer.The clamping
part and the inner steerer tube must not be
greased. If you are unsure about this, let
your bike mechanic carry out this work.
Danger!
Before every ride, check the se-
cure clamping of the adaptor and all steering
parts.The steerer rod bolts must be secured
with loctite and stop-nuts.
Never adjust the alignment of the handle-
bars to the front wheel by changing the
length of the steerer rod! The distance be-
tween the two rod pivots is a fixed measure.
The adaptor must stay perpendicular to the
front wheel, or the front wheel could sud-
denly turn in sharp corners!
