INDIVIDUAL CATEGORIES OF BIKES AND THEIR USES:
Children‘s bikes EN14765: All children‘s bikes up to the wheel size 20“ are intended for use in playgrounds and enclosed areas
and only under the supervision of parents or a responsible person. Recommended load of the wheel size 20“ up to 30 kg; wheel
size 24“ up to 45 kg.
MTB bikes EN14766: they are designed for sporty driving on the open ground. Recommended load up to 100 kg.
Trekking and city bikes EN14764: they are designed to operate on public roads and mild terrain, with a focus on recreation
and tourism. Recommended load is up to 120 kg, including the baggage.
If the weight of the cyclist, including the baggage, exceeds this load, please, contact your dealer who performs adjustments
and settings if necessary.
The first 150 km
The first 150 km can be defined as a warm-up round in which the life of a cyclist is filled with emotions and eventful experiences
from a new sport, on the other hand, the operational reliability and service life of the bike is being tested.
WHY A STARTING PERIOD AND WHY JUST FOR 150 km?
A little theory hurts nobody. Everything, during use, follows a certain law as to the number of defects depending upon the
length of its use. Mechanisms behave more or less obediently in accordance with the appropriately titled “bathtub-shaped curve”
of the occurrence of defects that consists in three quite different operational periods. The numbers of defects drop relatively steeply
at the beginning, a long section with a uniformly low occurrence of defects follows and in the end, defects will start to appear
more and more frequently.
The starting period represents the first stage; the second stage can be considered to be an optimum period of operation.
Long-term operation with a minimum number of defects is then a reward for your care and maintenance. An operational period
with increased supervision expressed as the distance of 150 km should be considered to be a period suitable for execution
of the first guarantee inspection specified on the basis of service experience. It is also based on the assumption that more
expensive and more frequently used bikes will be monitored more carefully by their owners. However, don‘t assume the date
of the first guarantee repair to be the day of the first inspection of your bike by anybody. That is to say, the service person could
replace certain components, such as cranks or shifters, replace them with new ones – and at your expense. It is necessary to state
that neglected maintenance is not covered even by a lifelong guarantee.
WHAT TO MONITOR DURING THE STARTING PERIOD
Even if your bike is adjusted correctly before operation, the production technology of components and their assembly requires some
time for the stabilization of correct operation. Generally, everything that moves and turns needs to find and smooth its path and
everything connected mechanically should settle mutually and create the required contact areas. Backlashes of rotational or sliding
assemblies are created by smoothing the roughness of contact surfaces while fixed connections are slackened.
What does this mean? The pedals may operate stiffly from the beginning but they can have considerable play after some time.
The same applies to the seatpost, with which adjustment of the saddle height was difficult. In the case of expensive components
with polished paths, this problem can mostly be eliminated by a single additional adjustment. Conversely, components with pressed,
often non-circular and small, hard surfaces for balls are difficult to adjust and achieving the status of an optimum setting for a long
period is practically impossible. Individual intensively monitored places, the neglected maintenance of which can have serious
consequences from the viewpoint of safe operation:
Recommendation: If parts or components of a bike become damaged as a result of use, replace them immediately!!! Use only
original spare parts purchased from authorized dealers!!! We recommend having your bike inspected by authorized service shops
at regular intervals, at least once a year! In case of an accident, we strongly recommend having the bike inspected professionally
in an authorized service shop.1. Connection of cranks with the axle
