Bike maintenance
Servicing & parts
We recommend servicing the
bike once a year or every 1000km,
whichever comes first.
As with all mechanical products,
this bike is subject to wear and
fatigue. Different materials and
components may react to wear
and 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
or change in colouring in highly
stressed areas indicates that the
end of life of the component has
been reached and that it should
be replaced.
Do not try to open or reach any
part of the electrical system of the
bike. There is a risk of injury and
permanent damage to the bike.
Always use approved Cowboy
spare parts should you need any.
Contact us via message in the
Cowboy app, or email us at
hello@cowboy.com.
Cleaning
Always take out the battery
before performing any
maintenance or cleaning.
Use a moist piece of cloth for
the frame and we suggest water
when cleaning the saddle. Bike
cleaning products can be used
to wipe down the frame. Do not
steam clean, high pressure clean,
or clean your bike and your battery
with a water hose.
Brake pads
Brake pads are an important
part of your bike and ensure that
you can always ride safely. It is
recommended to check them
every 1000km or as soon as you
feel decreased braking power or
hear a creaking noise. Your brake
pads have a wear indicator built in.
When the surface is worn away
so the small blue circle is visible,
it's time for a replacement set.
The brake pads you need to use
are the Shimano B05S.
The brake system is hydraulic
and can only be used with mineral
oil. Should the system oil need
to be topped up or replaced,
use mineral oil.
Tires
Your tires naturally wear over time
and need replacing. There is a
yellow Kevlar compound layer wear
indicator inside. When the tire is
worn and the inner layer becomes
visible, it’s time for a new one. If you
need to replace the inner tubes,
choose any tube with a Presta valve
(aka F/V) compatible with the
following tire dimensions (several
ways to define tire sizes):
• 58-559 / 62-559
• 26’‘x 2.25’’ / 26’’ x 2.4’’
If you can’t find tubes to fit those
dimensions, you may use smaller
ones such as:
• 60-559
• 26’’ x 2.4’’
If you need to remove the wheels
for any reason, reassemble the

Suspension seat post
Every month or whenever
the suspension movement is
significantly less smooth, apply
a light amount of grease to the
stanchion.
Every year or 1000km or whenever
the performance of the fork has
diminished (whichever occurs
first), ask a qualified person to
perform a maintenance, including
disassembling, cleaning, greasing
and inspecting the seat post.
front wheel through the axle with
10Nm torque and the rear wheel
nuts with 30Nm. For guidance
speak with us in the app or check
our online tutorials.
Belt drive
The carbon belt drive system does
not require lubrication. Applying
lubricant can cause the system
to malfunction.
Regularly inspect the belt and
sprockets carefully for signs of
deterioration. Make sure the belt
is always kept free of any debris
and clean it with water and a small
amount of soap if need be. Dirt and
dust hasten wear, which may cause
the belt to break unexpectedly.
When the belt is worn it will need
replacing.
Motor
For any motor-related issues,
please contact us directly rather
than trying to fix them yourself.
The motor is an auxiliary motor
limited to 250W of power and
provides assistance up to 25 km/h,
in compliance with EU regulations.
Note that motor assistance will not
function below -10°C or above
+60°C. The motor assistance
system’s A-weighted emission
sound pressure level at the rider’s
ears is less than 70 dB(A).

Suspension fork
Every month or whenever the
performance of the fork has
deteriorated (whichever occurs
first), apply a light amount of
grease to the wiper and stanchion.
Every year or 1000km or whenever
