IMPORTANT SAFEGUARDS:

IMPORTANT: READ ALL INSTRUCTIONS BEFORE USE.
RETAIN INSTRUCTIONS FOR FUTURE REFERENCE.

WARNING: Basic safety precautions should always be observed when

using an electrical appliance to reduce the risk of re, electrical shock or
serious injury.

The term “eBike” throughout this manual refers to your Electrically Power
Assisted Cycle.

Personal Safety:

• This eBike is intended for use as a commuter
and trekking bicycle. Using the eBike for any
other purpose may result in serious injury.

• Before you ride this eBike, practice riding in a
safe area free from hazards. Take time to learn
the eBike’s controls and performance. Practice
the controls and gain the experience necessary
to avoid any hazards you may encounter
while riding.

• It is your responsibility to identify and follow all
local laws and regulations, including tting your
eBike with any additional equipment necessary
to comply with local laws.

• Observe the applicable trafc regulations.

• At night your eBike MUST have white front and
red rear lights lit. It MUST also be tted with a
red rear reector and amber pedal reectors.

• Never ride with no hands.

• Adopt a speed that reects the terrain as well
as your riding ability.

• Use designated cycle paths when not using
public roads.

• When riding your eBike, wear
close-tting pants, or use a bicycle clip. Loose
clothing can get between moving parts and
cause serious injury.

• Wear clothing that attracts attention
when cycling.

• When riding your eBike, you should wear a
bicycle helmet that conforms to
current regulations.

• Your eBike saddle should be as close as
possible to horizontal. Do not tilt the saddle
backwards, as this can lead to pain and
physical injury.

• Take care when loading your eBike into a car or
when mounting it on a bicycle carrier.

• We DO NOT recommend that you use a bicycle
trailer with your Gtech eBike.

• You can t a Gtech approved luggage carrier to
your eBike. Please check with the manufacturer
to make sure that a child seat can be safely
attached to the luggage carrier.

eBike Safety:

• You must be over 14 to ride an eBike.

• The drive assist system is limited to a maximum
continuous power rating of 0,25kW (250W) and
a maximum speed of 25Km/h, (15.5 mph).

• Your eBike is designed for a maximum
permitted overall weight (rider + luggage +
bicycle) of 126kg. The maximum permitted
weight of the rider (85kg) plus luggage (25kg)
is 110kg.

• Do not submerge your eBike in water.

• Be aware that the speed at which you are
travelling may be faster than you are used to,
especially when starting off.

• Other road users may not realise that you
are on an eBike and that you are capable of
travelling at faster speeds.

Electrical Safety:

• Only use batteries and chargers supplied by
Gtech.

• Never modify the charger in any way.

• The charger has been designed for a specic
voltage, always check that the mains voltage
is the same as that stated on the rating plate.
A charger that is suitable for one type of battery
pack may create a risk of re when used with
another battery pack; never use the charger
with another appliance or attempt to charge
this product with another charger.

• Before use, check the charger cord for signs
of damage or ageing. A damaged or entangled
charger cord increases the risk of re and
electric shock.

3

• Do not abuse the charger cord. Never carry the
charger by the cord.

• Do not pull the cord to disconnect from a
socket; grasp the plug and pull to disconnect.

• Don’t wrap the cord around the charger
when storing.

• Keep the charger cord away from hot surfaces
and sharp edges.

• The supply cord cannot be replaced. If the cord
is damaged the charger should be discarded
and replaced.

• Do not handle the charger or the appliance with
wet hands.

• Do not store or charge the appliance outdoors.

• The charger must be removed from the socket
before removing the battery, cleaning or
maintaining the appliance.

Battery Safety:

• This appliance includes Li-Ion batteries;
do not incinerate batteries or expose to high
temperatures, as they may explode.

• Shorting the battery terminals may cause burns
or re.

• When the battery pack is not in use, keep it
away from paper clips, coins, keys, nails, screws
or other small metal objects that could make a
connection from one terminal to another.

• When you dispose of the appliance remove
the battery and dispose of the battery safely in
accordance with local regulations.

• You must always use the battery in accordance
with the instructions on the battery label.

• Liquid ejected from the battery may cause
irritation or burns.

• In an emergency situation contact professional
help immediately.

• Leaks from the battery cells can occur under
extreme conditions. Do not touch any liquid
that leaks from the battery. If the liquid gets
on the skin wash immediately with soap and
water. If the liquid gets into the eyes, ush them
immediately with clean water for a minimum of
10 minutes and seek medical attention. Wear
gloves to handle the battery and dispose of
immediately in accordance with local regulations.

Drive Belt Safety:

• Do not roll, pry, twist, invert or bend the belt
back on itself.

• Do not zip tie the belt.

• The acceptable temperature range for your belt
drive is -53°C to 85°C.

• Do not lubricate the belt drive.

• Keep body parts and clothing away from the
belt drive when in motion, otherwise they might
get caught in the belt drive.

• Replace the belt drive if there are any signs of

Brake Safety:

• Regularly check your brakes for signs of wear
and tear. Any worn parts must be repaired or
replaced immediately.

• Be careful while getting used to the brakes.
Practice emergency stops in a place clear of
trafc until you are comfortable controlling your
eBike.

• Wet weather reduces your braking power and
the grip of the brakes. Reduce your speed and
be aware of longer stopping distances when
cycling in wet conditions.

• Braking on unpaved surfaces will differ. Be sure
to practice braking on different surface types.

• Ensure that braking surfaces and brake pads
are free of wax, grease and oil.

Maintenance:

• Many parts on your eBike are subject to a
higher degree of wear due to their function
and depending on their use. Have your eBike
checked regularly at a professional bike shop
and have the worn parts replaced.

• After an accident or crash you must take your
eBike to a bike repair specialist to make sure
that it is safe to ride. Be aware that damage
may be invisible. Failure to do this may result in
serious injury.

• Any form of crack, scratches or change of
colouring in highly stressed areas indicate
that the life expectancy of the part has been
reached and it should be replaced immediately.

• Ensure the battery is removed from the bike
before carrying out any maintenance.

• Make sure that all screws and bolts are
tightened securely and to the prescribed
tightening torques before riding.

• You must always use genuine replacement
parts when performing maintenance on
your eBike.

• Regularly check the tyre pressures (maximum
75psi) and regularly check the tread depth of

Assembly

Make sure that you follow all of the instructions in this manual carefully to assemble your eBike cor­rectly before use.

We recommend that you build your eBike on a large, at and soft surface. You may need to put
something down on the surface to stop your eBike from getting scratched.

Carefully remove all of the packaging and ties from your eBike, as well as the 4 black plastic
wheel protectors and fork spacer. Take care not to damage or scratch the bike.

Check that you have all of the correct parts before you start to assemble your eBike.
See page 6 - 7.

For more information about the names and locations of the different parts of your eBike see page
8 - 11.

Make sure that the battery is removed from the bike before tting any parts.

Make sure that all screws are tightened securely before using your eBike.
For the correct tightening torques see page 69.

Assembly

Place the eBike frame upright on a at surface, you
may need to put something down on the surface
to stop your bike frame from getting scratched.
Make sure that the handlebar stem is sticking out
forwards and the brakes face the front. You can
adjust this by turning the front forks around.

Using the Gtech tool, carefully unscrew the
handlebar plate from the handlebar stem by
turning the screws anti-clockwise. Keep the 4
handlebar screws and washers safe – you will
need them later.

The brake levers should be horizontal and facing
away from the bike. The handlebars can be
rotated and adjusted to a comfortable position
if required.

Hold the handlebars in place at the centre of
the handlebar stem, making sure that they are
centred and the correct way round – the lines on
the centre of the handlebars will help you
do this.

Attaching the handlebarsAttaching the handlebars

16

Assembly

Note: When tted, the handlebar plate will not t
ush against the handlebar stem. There will be
a small gap. Ensure that the gap is even on the
top and the bottom of the handlebar.

Using the Gtech tool, tighten all of the screws
evenly by turning them clockwise. Tighten
in small increments in a criss-cross pattern.
The handlebars should be secure but do not
overtighten the screws.

Carefully insert the four screws (with washers)
making sure the threads are engaged well.
Screw in by hand, starting with two that are
diagonally opposite.

Place the handlebar plate so that it’s in front of
the handlebars and aligned with the holes on the
handlebar stem.
Note: The handlebar plate can go either way up.

Assembly

Make sure that all of the screws are tightened
securely, so that the handlebars do not move if
you try and twist them backwards and forwards.

IMPORTANT: After tting the
handlebar check carefully before your
rst ride. Loose or incorrect tting
of the handlebar can lead to loss of
control and the risk of serious injury.

Should you have any concerns
regarding the assembly of the
handlebar we recommend your
Ebike is checked by an experienced
mechanic or a professional bike shop.

18

Assembly

When closed, the quick release lever must lie at against the frame, fork and
saddle clamp, otherwise it could snag on obstructions when the bike is moving.
This could lead to serious injury.

Attaching the saddle

The seat tube has a quick-release tting on it to make it easier to attach and adjust the saddle’s height.
To operate the quick-release, follow these instructions:
Refer to page 38 for adjusting the saddle to the recommended height and position.

1. Pull back the quick-release lever.

2. Insert the saddle post into the frame.

Drop the saddle’s seat post down to its lowest
position and make sure that the saddle is in line
with the eBike’s frame.

Check that the saddle cannot move once the
quick-release is closed. If it does move, tighten
the adjusting nut, until you need to use the palm
of your hand to close the quick-release lever.

Close the quick-release by rmly pushing on the
quick-release lever, so that it lies at against the
frame.

19

Assembly

Turn the black adjustment nut anti-clockwise and
remove it from the front wheel quick release lever.
Keep the adjustment nut safe.

Remove the spring that was closest to the
adjustment nut and keep it safe.

Push the quick-release through the centre of the
front wheel.

Place the frame upside down on a at surface,
resting the saddle and handlebars on the oor.
You may need to put something down on the
surface to stop your bike frame from getting
scratched.

Make sure that the 2 black plastic wheel protectors have been removed from the wheel. Be careful
when removing these, so they do not snap off and become stuck in the wheel. Remove the front fork
spacer.

How to t the front wheel

20

Assembly

Fit the spring onto the quick release shaft, with
the narrow end facing towards the wheel.

Screw the adjustment nut onto the end of the
quick-release, next to the spring, by turning it
clockwise. Only 2 to 3 turns are required, leaving
a gap to slot the front wheel onto the forks.

Note the direction of rotation marked on the tyre
should be the same as on the rear wheel. Align
the front wheel with the fork holders and slot in
place, ensuring that the wheel ts tight within the
fork holders.

While holding the quick-release lever in line with
the wheel hub tighten the adjustment nut on
the opposite side by turning it clockwise until
resistance is felt.

21

Assembly

The closed position is with the lever in line with
the front fork with “close” visible.

Push the quick-release lever fully closed.
You should need to use the palm of your hand
to close the quick release lever with as much
strength as possible.

If the lever is too easy to close return it to the
open position and tighten the adjustment nut a
quarter turn clockwise. Repeat as required.
If the lever is too stiff to close return it to the open
position and loosen the adjustment nut a quarter
turn anti-clockwise. Repeat as required.

Make sure that the wheel can rotate
freely.

Make sure the quick release lever
is in fully closed position and that
the wheel is attached securely.
Incorrect tting may result in the
wheel becoming loose when riding
or the quick release lever snagging
on obstructions. This could lead to
serious injury.

Should you have any concerns
regarding tting the wheel we
recommend your bike is checked
by a professional bike shop.

22

Assembly

Fully tighten both pedals from behind the crank,
using the 6mm allen key provided.

Make sure you rotate the pedal by the hexagonal
section, not the pedal itself, which will just spin
free.

Fitting the pedals

Match the pedal marked L with the crank marked
L, located on the opposite side to the drive belt.

Carefully align the pedal into the crank hole.
Poor alignment will damage the screw thread.
Tighten by using your ngers to turn the pedal
spindle anti-clockwise.

Match the pedal marked R with the crank marked
R, located on the opposite side to the drive belt.
Carefully align the pedal into the crank hole.
Poor alignment will damage the screw thread.
Tighten by using your ngers to turn the pedal
spindle clockwise.
