5 | MAINTENANCE
Servicing and repairs can be tricky and complex. Careless or unprofessional servicing can
lead to the failure of certain bike components. Danger of accident! Only carry out work for
which you have the necessary knowledge and the appropriate tools. Otherwise, it is best to
have these tasks carried out by your authorised dealer.
5.1 BATTERY
The battery is the most important element on your Moustache.
By respecting a few simple rules, you can optimize its lifespan.You will find lots of informa-
tion in the Bosch notice delivered with your Moustache, but here is a little advice:
• Do not stock your battery without any charge for prolonged periods; the battery
can go into a deep discharge which will shorten its lifespan.
• Get into the habit of recharging it at your return from riding, then your bike will
always be ready to go.
• The Bosch battery can be stocked without use or charging for up to a year, but
it must be left charged to 50/60% (3 leds).
• Even if it can bear being stocked in temperatures of -20°C to +60°C, you will
optimize its lifespan if you keep it at an ambient temperature (20°C).
• Respect the temperature conditions for usage which are -5°C to 40°C.
• Never leave your battery exposed to high temperatures or in direct sunlight for
a long period (for example in the back of a car in full sunlight).
• Ensure that the contact points are always clean and do not insert metallic
objects.
• The Bosch batteries are specifically conceived in order to be recyclable.
• Do not throw them away in normal rubbish or the tip. There is a specific treatment
(ask your local Moustache retailer for advice).
• Be careful, the transport of Lithium-ion batteries is subject to strict rules.
If you have any questions, please consult your local retailer.
5.2 USING ORIGINAL PARTS
It is strongly recommended to use the original parts for all components that are critical for
safety.
The use of parts that are non-compliant with your bike, as well as any modification to
the frame or parts can cause risks for the user of the bike as well as a restriction of the
guarantee.

Replacing cranks and tires
If you wish to change your cranks to increase their length, you should first check that they
will not pass too close to the chain stays. Please also check that your shoe will not touch
the wheel or the mud guard when the cranks are in a horizontal position and you turn the
handlebar. This same check should also be carried out if you increase the width of the front
tire.
What's more, if you increase the length of your cranks, you will decrease their distance from
the ground, so you are at risk of touching the ground if pedaling when cornering or on rough
terrain, and therefore risk a fall. Ask your retailer for advice.
5.3 CLEANING AND LUBRICATION
After each ride, you should clean your bike with soapy water (washing up liquid is advised
for its powerful degreasing qualities, without being corrosive). However, do not use a high-
pressure hose, as far as possible.
If you cannot clean it otherwise, never direct the jet directly at the bearings and seals, nor
at the motor and the battery.
We also advise you to remove the battery and the on board computer during cleaning,
and to wash them separately using a damp cloth. Dry them with the aid of a soft cloth to
eliminate any drops of water and residues of humidity in order to avoid the risk of corrosion.
Doing this will also enable you to carry out a visual check of the tubes of your bike (useful to
check for the start of any possible cracks).
Before storing your bike away, lubricate the transmission with a product specially designed
for this. Also check the wear on your brakes, any possible buckling of the wheels and for
any play.
Beware of the potential risks of being pinched, trapped, or caught and drawn in during
maintenance work.
5.4 WEAR PARTS AND INSPECTION FREQUENCIES
As for any mechanical element, your Moustache bike is subject to high rates of
stress and wear. The different materials and components can react in different ways
to wear or to fatigue. If the envisaged life span of a component has been passed,
this can break suddenly, therefore risking injury for the rider. Any cracks, scrapes or
discoloration in zones subject to high levels of stress are an indication that the part
has passed its usable life and should be replaced.
Regularly check all wear parts, especially parts for the brakes and the transmission in order
to not take risks. If you have any doubt about the level of wear on any part, please check
the manufacturer's notice or check with your retailer. Prevention is better than cure, so don't
wait till the last moment!
