Introduction
Original instructions (user manual/instructions for use) are written in English. All other
languages are translations of the original instructions (user manual/instructions for use).
In case of any dispute, the user manual in English prevails.
This user instruction manual is developed for your Greyp bike only. It contains important
safety, performance and technical information, which you should read before your rst ride
and keep for reference. You should also read the entire User Manual, because it contains
additional important general information and instructions that you should follow.
If you do not have a copy of the User Manual, please download it for free at
www.greyp.com or obtain it from your nearest Authorised Greyp Retailer. In case of
discrepancy, the english version shall prevail.

General warning
This manual contains many “WARNINGS” and “CAUTIONS” concerning the consequences of
failure to maintain or inspect your bike and of failure to follow safe cycling practices.
The combination of the safety alert symbol and the word WARNING indicates a potentially
hazardous situation which, if not avoided, could result in serious injury or death.
The combination of the safety alert symbol and the word CAUTION indicates a potentially
hazardous situation which, if not avoided, may result in minor or moderate injury, or is an alert
against unsafe practices.
Many of the WARNINGS and CAUTIONS say you may lose control and fall. Because any fall
can result in serious injury or even death, we do not always repeat the warning of possible
injury or death.
As it is impossible to anticipate every situation or condition which can occur while riding, this
User Manual makes no representation about the safe use of the bicycle under all conditions.
There are risks associated with the use of any bicycle which cannot be predicted or avoided,
and which are the sole responsibility of the rider.

5 HANDLEBAR POSITIONING
1. Rotate the handlebar to its natural position (≈90° to the frame, “centered ”).
2. Using the tool (three-arm hex key number 5), lightly tighten the two bolts on the stem.

1. Guide your wheel into the fork and guide the rotor between the brake pads.
2.
Tighten the axle - line up your hub with the holes at the bottom of your fork. Check which side of the fork
is threaded and push the axle in from the opposite side. Turn the three-arm hex key number 6 clockwise to
thread the axle into the fork.
7 PEDALS MOUNTING (G6.1, G6.2, G6.4, G6.5, G6.6)
1. Take the pedals out of the box, grease
the thread and tighten them using the
tool (three-arm hex key number 6) (see
picture above).
2. Pay attention to the direction of
rotation
while tightening. The thread
on the right pedal is right-handed
(standard). The direction of rotation for
tightening is anti-clockwise. The thread
on the left pedal is left-handed so the
direction of rotation for tightening is
clockwise.

CHECK (G6.3)
1.Take the pedals out of the box, grease
the thread and tighten
them usingthe tool
(L shaped 8 allen wrench - see picture).
2. Pay attention to the direction of
rotation
while tightening. The thread on
the rightpedal isright-handed (standard).
The direction of rotation for tightening
is anti-clockwise. The thread on the left
pedal is left-handed so the direction of
rotation for tightening is clockwise.
8 HANDLEBAR MOUNT
1. Slightly loosen the 2 bolts on the stem.
Tighten thetop cap (headsetbolt) to 6Nm
using the three-arm hex key number 5).
2. Center and tighten the 2 bolts on the
stem. The easiest way to get everything
“centered” is to stand in front of your bike
and hold the front wheel between your
feet and legs. Tighten the 2 bolts on stem
(headset bolt) to 12Nm.
9 CHECK
Grab the front brake and use the bars to push/jolt the bike forward. If you feel that the headset is loose (a clinking
sound, or any movement other than the rear wheel coming off the ground), tighten the top cap, but
be careful how much you tighten it (three-arm hex key number 5). The top cap bolt will determine how
loose or tight your headset is, so it plays a major role in the steering and feel of your bike. Tighten the bolt
a little at a time and between each turn.
Once the looseness in the headset is gone, it should be tight enough.
Give the handlebar a turn to the left and
right
to make sure they still move smoothly. If the movement is tight, you’ve gone too far. Back the stem

cap off a quarter to half a turn and try again. Once there is no looseness in the headset and the handlebar
is smoothly turning, you need to take the tool (three-arm hex key number 5) and tighten the two bolts on
the stem (see picture).
Flip your bike over and spin your wheel: by spinning your wheel, you will make sure your brake pads are not
rubbing on the rotor. If your wheel does not spin, it could be crooked in the fork’s dropouts. Flip your bike
back, loosen your axle, push down on the wheel and tighten the axle again.
