About this instruction
manual
This instruction manual provides
you with the information you
need to maintain and use your
Koga bicycle safely. The manual
describes only the major parts of
the bicycle and the most common
settings. This manual is intended
for all types of bicycles from
Koga. That means that certain
information might not apply to
your Koga bicycle.
Visit www.koga.com to find the
most up to date version of this
document.
Manuals for specific parts may
have been supplied along with
your Koga bicycle.
Consult these manuals if you
want extra information about the
part in question. If you want more
information about a certain part,
or you want to make adjustments
that have not been described
in these manuals, contact your
Koga dealer.
Safety
Use the bicycle for the
purpose for which it
was designed.
Traffic
Every rider is legally obliged to
maintain his or her bicycle in a
condition that is safe for traffic
and ready for riding. Make sure
you are familiar with these legal
obligations so you are not faced
with unwelcome situations.
Koga supplies bicycles that
meet the legal obligations for
the purpose for which they are
made. The Trekking, Comfort,
Special and most of the Light
Touring bicycles are suitable for
public roads. The Race, MTB and
a few Light Touring bicycles are
not suitable for public roads if
they do not have the necessary
adjustments. In their standard
models they do not have any
lighting, and therefore may
not be ridden on public roads
in conditions of poor visibility.
Separate light units are available
for these bicycles.
Ride particularly
carefully on wet road
surfaces. The braking
distance is longer on a
slippery road surface.
Use lights that work
properly in all cases of
poor visibility.
(Cycle) clothing
When riding your bicycle, wear
close-fitting pants, or use a
bicycle clip. Loose clothing can
get between moving parts.
Koga is not liable for
grease and/or lubricants
in clothing.
When riding your bicycle, wear
clothing that attracts attention.
When riding your bicycle, wear a
DIN-EN 1078 approved bicycle
helmet.
Before you start riding, check
that:
• The wheels are properly
mounted.
• The brakes work properly.
• The saddle is at the correct
height.
• The seat post is at the correct
height.
• The seat post is at the correct
height.
• The lights work properly.
• The gears work properly.
• The bolts, nuts and pedals are
attached firmly.
• The air pressure in the tyres is
correct.
• The tread of the tyres is
correct.
After an accident
After an accident or a fall, have
your Koga dealer check your
Koga bicycle thoroughly.
• A bent or deformed aluminium
frame cannot be repaired.
• A slightly bent or deformed
steel frame can be repaired.
• After an accident, carbon parts
must be replaced entirely.
Carbon parts can receive
visible and invisible damage.
Accessories and equipment
You can mount extra accessories
on your Koga bicycle. All parts
that are mounted additionally on
the bicycle must be suitable for
the Koga bicycle. Therefore, use
accessories only in consultation
with your Koga dealer. Parts that
do not fit can lead to damage or
accidents.

braking distance is always
longer.
• Make sure no limbs can come
between moving parts.
• Make sure fingers cannot come
between suspension parts of
the saddle.
• Never transport more weight
on the luggage carrier than

Bicycle carriers
A number of types of bicycle
carriers (on car, caravan, camper
etc.) can damage your bicycle
when mounting or transporting
it. An incorrect mounting position
or tightening the mounting
construction too far can cause
damage to the frame/front fork.
The damage to the frame or fork
can result it in it breaking.
Environment
Dispose of excess lubricants,
cleaning agents and paints.
Dispose of these agents as
specified on their packaging and
take local legislation into
consideration. If you are
discarding a bicycle, return it
to your Koga dealer or dispose

authority‘s.
Proof of ownership
Have your Koga dealer fill in the
proof of ownership completely, and
place his signature and business
stamp. Check that frame number
is filled in. Store the proof of
ownership carefully. It is also the
guarantee. The proof of ownership
is unique and can therefore only be
issued once.
Guarantee

guarantee on your Koga bicycle
(Details page 22). You are also
entitled to a lifetime guarantee for
the frame against manufacturing
faults. The guarantee period
starts on the day of sale by the
dealer. The guarantee is solely

indication of the brakes.
When the brakes wear out, the
braking power can decrease.
1. Release the brake lever.

Brake Power Controller (4A)
administers the braking power.
This means you can brake more
safely.
