Even though there are currently no laws that require you to wear a helmet, you should think about your own safety and therefore wear a helmet when cycling. The ADAC recommends that children, young people and sporty cyclists in particular wear a helmet for protection.
Microshell helmets have a thin plastic cover and are the most common. These models are made of thin polycarbonate, which is primarily found in lightweight sports models.
The hardshell helmets have a hard plastic cover around the foam (polystyrene foam) and are mainly used for downhill riding due to their high weight. The "hardshell" material is made of ABS (acrylonitrile butadiene styrene) and is somewhat stronger and heavier, which is why it is also used in motorcycle helmets.
The straps of the helmets are made of polyester and the buckles are made of solid polyamide or POM (polyoxymethylene).
The materials used in the manufacture of helmets can be found online in the information on the article or in the product's instructions for use.
The helmet should fit your head snugly, but not too tightly, and above all it should not slip. The straps should not be twisted. If this is the case, put your helmet on straight and bring the straps down so that they pass in front of and behind your ear.
Then you can close the chin strap buckle, which should rest under your chin when the chin strap is taut.
If your bike helmet has a knob at the back, you can adjust it individually to your head shape so that it neither slips nor presses.
It is advisable to measure above the ears and across the middle of the forehead, about three centimetres above the eyebrows. You should not stretch the tape measure over your neck, but keep it on your head.
I recommend that you measure a second time to get the correct measurement.
The right bicycle helmet size or the size of the head cannot simply be divided into age groups, but depends on the individual child.
You will find the following guidelines for children on the market, which may vary slightly depending on the manufacturer and brand:
44 to 49 centimeter
0 till 3 years
46 to 51 centimeter
2 to 7 years
49 to 53 centimeters
3 to 9 years
52 to 58 centimeters
4 to 80 + years
You should not rely on these general values, but measure your child's head exactly to determine the appropriate size.
However, there is a general recommendation for cyclists to wear a bicycle helmet when riding in traffic. Especially for children under the age of twelve, experts strongly recommend wearing a bicycle helmet.
You should think of your child's safety first and foremost and therefore always let your child wear a helmet when riding a bike.
The materials of a helmet are also subject to ageing. This reduces the protective effect of the material, which is why you should replace your bicycle helmet after about three to five years.
Too much UV light can also damage the plastics and adhesives. Therefore, you should not store your bike helmet in the sun or in a warm car, as the shell of the helmet can deform.
