To define the intended purposes for the different types of bicycles, we have classified our bikes in different categories. The purpose of this classification is to define the test requirements complying with the respective
stress as early as during the development of our bikes. This is to ensure the highest possible level of safety for the use of our bikes.
It is therefore of major importance that the bikes are not used under conditions beyond the intended use, as this bears the risk that the bikes’ maximum load is exceeded and the frame or other components are damaged. This can result in severe crashes.
The rider’s maximum weight incl. baggage should not exceed 120 kg. Under certain circumstances this permissible maximum weight can be further limited by the component manufacturers’ recommendations for use. The frame of your bike is marked according to one of the following symbols indicating the category your bike belongs to. Picture 1
This category is intended for childrens’ bicycles. Children should not ride near precipices, staircases or swimming pools as well as on paths used by automotive
mobiles. In general, this applies to bicycles with wheel sizes of 12 to 24 inches.
Bikes of this category are designed for riding on hard-surface roads where the wheels remain in permanent contact to the ground. These are in general
road racing bicycles with racing handlebars or straight handlebars, triathlon or time trial bicycles.
The rider’s maximum weight incl. baggage should not exceed 120 kg. Under certain circumstances this permissible maximum weight can be further limited
by the component manufacturers’ recommendations for use.
Bicycles of category 1 and bicycles designed for well paved gravel paths and off-road trails with a slight slope where a short loss of tyre contact with the
ground due to small steps can occur. This condition comprises urban and city bicycles as well as cyclocross bikes with road racing handlebars and cantilever
or disc brakes.
Bikes of this category comprise the bicycles of the categories 1 and 2 and are in addition suitable for rough and unpaved terrains. Sporadic jumps of a
maximum height of approx. 60 cm are also included in the field of use of these bicycles. But inexperienced riders doing jumps of this height may land inappropriately, thus increasing the acting forces significantly which may result in damage and injuries. This category is represented by MTB hardtails and full suspension bicycles with short suspension travel.
This category includes bikes of the categories 1 to 3. In addition, bicycles of this category are suitable for very rough and partly blocked terrain with steep
slopes and higher speeds as a result thereof.
Regular, moderate jumps by experienced riders are no problem for these bicycles. The regular and durable use of the bicycles on North Shore trails and in
bike parks should, however, be excluded. Due to the higher stresses, these bicycles should be checked for possible damage after every ride. Full suspension
bikes with medium suspension travel are typical for this category.
This type of use stands for very challenging, highly blocked and extremely steep terrains, which can only be mastered by well-trained riders with technical
skills. Rather high jumps at very high speeds as well as the intensive use of specific, identified bike parks or downhill trails are typical for this category.
In the case of these bicycles it must be considered that a thorough check for possible damage is carried out after every ride. Preliminary damage with clearly
inferior further stress can result in failure. A regular replacement of safety-relevant components should also be taken into account. Wearing special protectors
is strongly recommended. Full suspension bikes with long suspension travel as well as dirt bikes are
typical for this category
