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.

INTRODUCTION
6
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.

The Greyp G6 is classied as a pedelec. The G6 is a vehicle where the rider’s pedalling is assisted
by an electric motor with 5 assist and torque levels, which gives you a range of power assistance.
Motor support will automatically switch off when you reach a maximum speed of: 25km/h for
G6.1 and G6.2; 32km/h (20mph) for G6.1(US) and G6.2(US); 45km/h (28mph) for G6.3 , G6.2O,
G6.2O(US) and G6.3 (US). A driver’s license or insurance is typically not required. Regardless
of its classication, it will only provide motor support only while pedalling.
Before using your Greyp bike, please inform yourself of all applicable legal requirements and
regulations in your country or state. There may be restrictions on riding your Greyp bike on
public roads, cycling paths, and/or trails. There may also be applicable helmet requirements, age
restrictions or license or insurance requirements. As laws and regulations regarding electric vehicles
vary by country and/or state and are constantly changing, please make sure you obtain the latest
information. You should also regularly see your authorized Greyp retailer for updated information.
All Greyp G6 bikes have a xed pre-set speed limit at which the motor support will automatically
shut off. Tempering is to interfere with bike in order to cause damage or make unauthorized

alterations (i.e. excluding the exchange of sprocket with non-original parts) Any (attempted)
tampering with the power output and/or system (i.e. excluding the exchange of sprocket with
non-original parts) is prohibited, will void the warranty, is extremely dangerous and could
result in severe and/or fatal injuries. In case of tampering we recommend that you stop using
bike and call authorized Greyp retailer.
Safety information
Please, carefully read all the warnings and notes in this User Manual before using your Greyp bike.
WARNING — You add to your risk of injury when you use your bicycle in an incorrect manner.
Misuse can add stress to your bike. High stress can cause the frame or a part to break and
increase your risk of injury. To decrease your risk of injury, use your bicycle in the manner for
which it was designed.
WARNING — As with all mechanical components, the EPAC (Electrically Power Assisted Cycles)
is subjected to wear and high stress. Different materials and components may react to wear
or stress fatigue in different ways. If the design life of a component has been exceeded, it may
suddenly fail, possibly causing injuries to the rider. Any form of crack, scratches or change of
colouring in highly stressed areas indicate that the lifespan of the component has been exceed-
ed and it should be replaced.
WARNING — For composite components, impact damage may be invisible to you and may
result in serious personal injury or death. If composite components exhibit any signs of damage,
do not use them and immediately bring them to your authorized Greyp retailer for inspection.

WARNING — Inappropriate handling of a Greyp bike can cause damage, injury and/or death.
Please make sure you learn how to operate your Greyp bike in a safe and responsible way.
The Greyp G6 is intended to transport only one person at a time. If you allow somebody else
to use your Greyp bike, please provide them with this User Manual.
We advise keeping the original box that the bike came with for the warranty period in case
there are any troubles.
WARNING — We strongly advise you to wear a helmet and other safety equipment while riding
your bike. In some countries, there is an obligation to wear a helmet. Please check if this is
the case in your country.
Only ride at ambient temperatures between 5°C (41°F) and 40°C (104°F).
WARNING — Greyp lights are primarily designed as auxiliary lights and you should take care
that you use lights that are in accordance with the provision in force in the country of use.

GENERAL NOTES ABOUT RIDING 9
General notes about riding
The G6 motor provides pedal assistance while you are pedalling, and the the bike is in motion.
The amount of pedal assistance will be higher or lower depending on the amount of force
applied to the pedals. If you stop pedalling, the motor will stop providing any assistance. The
Greyp G6 can also be ridden as a normal bicycle without motor assistance by switching the
vehicle to the OFF mode. The same applies if the battery is empty.
The Greyp G6 has a walk-assist mode (the motor engages without pedal force being applied)
which is designed to provide assistance when walking the vehicle up a hill.
Riding tips
Below are some riding tips, which may also reduce component wear and increase battery range.
»Pay attention to your speed when going into a corner and be sure to stop pedaling
well before entering the corner. Otherwise you may have too much speed as you
enter the corner ;
»Ride efciently and look ahead. Any time a braking force is applied, more energy is
needed to get the vehicle back up to speed ;
»Shift gears regularly to stay in an optimal cadence range and downshift before
coming to a stop ;
»Reduce pedal force before initiating a gear shift to reduce drivetrain wear ;
»Check the tire pressure regularly. Low pressure can cause the tires to roll
inefciently ;
»If your vehicle is exposed to cooler weather, keep the battery stored indoors until
just before riding ;
»Do not expose your vehicle to excessive heat ;
»Only carry the cargo you need. More cargo weight requires more energy to move.

GENERAL NOTES ABOUT RIDING
10
WARNING — Improper derailleur shifting technique could cause your chain to jam or come off,
causing you to lose control and fall.
Pre-Ride Inspection
»Prior to the rst ride, charge the battery to 100% ;
»Check to ensure that the quick-release levers or axle nuts are tight ;
»Check the brake pads for excessive or uneven wear ;
»Make sure that all bolts on the brakes and steering parts are tight ;
»Spin the rims – check for wobbles while sighting on the rims
»Check the tire pressure ;
»Check the tires for excessive wear, cracking or gashes ;
»Check that the gears shift smoothly ;
»Check the chain for rust, dirt, stiff links or noticeable signs of wear (the chain
should be clean and lubricated, be sure to use a chain-elongation gauge) ;
»Apply the front brake, and push the bike forward and backward (the headset
should be tight and not make any clunking noises).
WARNING — Being aware of your surroundings can drastically reduce incidents. If you are on
the road be aware of trafc and road conditions. In off-road conditions there may be less friction
between the tires and the ground and it can make you lose control and cause an accident.
CAUTION — Your eld of view is particularly shorter, in fact very short, when riding at night.
Obstructions are more difcult to see at night. Use extreme caution, slow down to compensate
for the much shorter reaction time and ride at a speed appropriate to your eld of vision and
surroundings.
Riding tips for children
Greyp bikes are only designed and tested for use by one person at a time. Greyp bikes are
not intended for children under 16 years. Do not allow children under 16 years old to drive a
Greyp bike.
Seat post – basics
WARNING — Make sure that the seat position is adjustable so that the feet of a seated rider can
touch the ground. If your bicycle does not t properly, you may lose control and fall.

GENERAL NOTES ABOUT RIDING 11
WARNING — After any saddle adjustment, be sure that the saddle adjusting mechanism is
properly seated and tightened before riding. A loose saddle clamp or seat post clamp can
cause damage to the seat post, or can cause you to lose control and fall. A correctly tightened
saddle adjusting mechanism will allow no saddle movement in any direction. Periodically
check to make sure that the saddle adjusting mechanism is properly tightened.
Seat post
MIN
INSERT
Greyp G6 bikes have a telescopic seat post.
Familiarise yourself with the features of the
seat post before your rst ride. Only operate
the telescopic seat if it will not distract any of
your attention from the road and terrain. Refer
to information from the telescopic seat post
manufacturer (www.kssuspension.com). A
telescopic seat post allows the saddle height to
be adjusted by operating a lever underneath the
saddle or a remote control on the handlebars,
both at a standstill and while ridding.
The saddle height is always measured with the
crank arm pointed down and in line with the
seat tube. The distance from the centre of the pedal axle to the top of your saddle is your
saddle height. Before changing the height of your saddle, you should measure your current
saddle height.
All seat post models must be inserted into the bike seat tube to cover the minimum insertion
line indicated on the seat post. Insufcient insertion of the seat post into the bike’s frame seat
tube frame’s seat tube could result in damage to the seat post and/or vehicle and may result
in a loss of control of the vehicle, which may lead to serious injury or death.
To lower the saddle, weight the saddle rmly with your hand or sit on the bike while pressing
and holding the actuation lever or remote. Release the lever when the desired height is reached.
To raise the saddle, actuate your seat post by pulling the lever or handlebar remote. Unweight
the saddle and release the lever when the desired height is reached.
You can raise and lower your saddle to any desired position within the seat post’s travel.
Brakes – basics
WARNING — Braking devices on Greyp bikes are a high-performance product, offering a
stopping power greater than normal brakes. As a result, less effort is required to lock up the
wheel when braking. Be careful, as a locked wheel can result in loss of control over the vehicle
and can cause injuries. Brakes are essential for the safe use of a vehicle - an improper setup
and use of the brakes can make you lose control and cause an accident, with unpredictable
consequences and/or potentially serious injuries. Disc brakes get VERY hot when used.
Commonly the left lever operates the front brake and the right lever operates the rear brake
(this may vary depending on country).

GENERAL NOTES ABOUT RIDING
12
CAUTION — NEVER touch the calliper or the rotor immediately after use. Make sure the brakes
have cooled down before working on them.
The brake rotors must be installed on wheels that are suitable for this type of brake system.
A wheel with an insufcient spoke section or with radial spoke lacing can break under normal
use of the braking system and cause serious injury, accident or death. Check with your wheel
manufacturer BEFORE installation to ensure compatibility.
Check the spoke tension and condition frequently. A damaged spoke may break suddenly and
interfere with the braking system. This may result in serious personal injury, accidents or death.
WARNING — Before every ride, make sure there are no fluid leaks in the system by applying
the lever and holding it down as far as it will go. Check the hose connections and the brake
fluid reservoir for any leaks. Consult a professional mechanic if there are fluid leaks. A fluid
leak can cause a serious accident or death!
CAUTION — Braking distances may be greater in wet weather and use of the brakes can make
you lose control, fall and cause an accident.
Test the brakes and your braking technique on flat and even ground before using the bike in
more severe conditions.
You can nd more info about Formula Cura brakes on www.rideformula.com
Suspension – basics
WARNING — Improperly installed, maintained or adjusted components are extremely
dangerous and could result in severe and/or fatal injuries. If you have any questions about the
installation of these components, consult a qualied bicycle mechanic.
Rear Suspension
Suspension sag can be used to set the proper suspension spring rate for the rider. Sag is
the amount (percentage) the suspension compresses when the rider, including riding gear,
is seated on the bike in the riding position. Setting the proper sag allows the wheels to
maintain traction without using too much of the travel reserved for shock absorption. More
sag increases small bump sensitivity, while less sag decreases small bump sensitivity. Set the
spring sag before making any other tuning adjustments. G6.1 & G6.1(US) are using Rock Shox
Monarch RT1 216x63 and G6.2, G6.2O, G6.2O(US), G6.2(US), G6.3 & G6.3(US) are using Rock
Shox Monarch RT3 216x63.
Before setting sag, set the dampers to the full open positions. Rotate the adjusters counter-
clockwise until they stop. Set the shock to the open position.
Beginning with the shock fully deflated, pressurize the air spring chamber to 100 psi. Remove
the pump. Do not compress the suspension with the pump attached.
Fully compress the shock ve times to equalize the positive and negative air springs.

GENERAL NOTES ABOUT RIDING 13
Pressurize the shock (PSI) to the equivalent of the rider’s total weight (lbs), including gear.
Example: 160 lbs = 160 PSI (0.15 bar = 1 kg). Remove the pump. Compress the shock once
more to equalize air pressure.
With your riding gear on, and an assistant holding the bike, step onto the vehicle and lightly
cycle the shock two to three times.
While seated on the bicycle, have an assistant slide the sag o-ring against the wiper seal.
Gently step off the vehicle without compressing the shock.
Note the sag percentage where the o-ring stopped. The correct sag percentage for Debon Air
shocks is 30%. Sag can be set ±5% as preferred. If your target sag percentage is not achieved,
air pressure must be adjusted. Increase air pressure to decrease sag. Decrease air pressure
to increase sag.
Adjusting rebound
Monarch rebound damping controls suspension rebound speed after compression.
Suspension rebound speed affects the wheel contact with the ground, which affects control
and efciency. The shock should rebound quickly enough to maintain wheel traction without
feeling ‘bouncy’. Too much rebound damping will not allow the shock to rebound quickly
enough for the next bump. To increase the rebound speed, rotate counter-clockwise. To
decrease the rebound speed, rotate clockwise.
Adjusting the threshold (only for models G6.2&G6.3)
The threshold, or pedal setting prevents the shock from compressing until moderate impact
or downward force occurs. Use the threshold setting to increase pedalling efciency on flat,
rolling, and smoother terrain. To activate the threshold setting, rotate the lever, or actuate the
remote until it reaches the threshold position indicated on the shock.

GENERAL NOTES ABOUT RIDING
14
Adjusting the lockout
The lockout setting prevents the shock from compressing until signicant impact or downward
force occurs. The shock will compress when the force exceeds the damper blow-off circuit
resistance. Use the lockout setting for maximum pedalling efciency on smooth or rolling
terrain. Rotate the lever, or actuate the remote, to lock and unlock the compression damper.
You can nd more info about rear suspensions on www.sram.com/rockshox.
Front suspension
Rebound damping controls the suspension fork extension/return speed, which affects
traction and control. Optimal rebound damping allows the fork to extend at a controlled speed
and maintain traction and control. Rebound that is too fast allows the fork to extend too
quickly, which causes the wheel to bounce off objects and the ground resulting in a pogo
effect. Rebound that is too slow prevents the fork from extending quickly enough to regain
contact with the ground or prepare for the next impact. Rebound damping can be tuned to
rider weight, spring rate and travel, as well as for terrain and rider preference.
As the air pressure or spring rate increases, the extension/return speed increases. To achieve
the optimal setting, rebound damping may need to be increased when air pressure or spring
rate increases.
For recommended rebound settings, go www.sram.com/rockshox.
After setting the sag, adjust the rebound damper, go for a ride, and adjust again as preferred.

Recommended tire pressure
The tire pressure is an important factor for riding your bike properly. If the tire pressure is
too high, the tire will not conform to the ground, reducing traction. It is important to have an
accurate pressure gauge when setting the tire pressure; preferably a digital gauge with a 0.03
[bar] (0.5 [psi]) accuracy.
The recommended tire pressure will vary slightly based on rider weight, riding style, and
terrain. Some riders may nd it helpful to start a ride at a slightly higher pressure than
recommended and let out a little air throughout the course of the ride until you nd your ideal
riding tire pressure.
The maximum inflation pressure is 2.6bar (38psi)
WARNING — If the maximum pressure values in this manual and values on the side wall of a
tire are in any way different, please refer to the ones that are marked on the tire’s sidewall or
wheel (which ever is lowest). Never inflate a tire beyond the maximum pressure marked on the
tire’s sidewall. Exceeding the recommended maximum pressure may blow the tire off the rim,
which could cause damage to the bike and injury to the rider and/or bystanders.
You can nd the minimum recommended tire pressure on the tire side wall. Never inflate tire
below the minimum recommended tire pressure. If the tire pressure is too low, the tire could
pinch flat and be difcult to handle and can cause loss of control.
