Always beware of electric vehicles, motorcycles and tricycles. This kind of vehicle often does not act according to common sense and frightens you to urinate every minute.

During cycling, both eyes should look forward as far as possible, and allow enough time to judge obstacles such as potholes and broken glass on the road.

It is added that the principle of helmet protection is that the helmet wearer can make the impacted head stop relatively slowly, while if the helmet wearer hits the head on the ground, it will often cause brain edema and bleeding, while the spherical objects in the helmet can absorb the impact force, avoiding the occurrence of these unfortunate events.
Electric vehicle helmet At present, there is no unified quality standard "common helmet shells are made of engineering plastics, glass fiber reinforced plastics, carbon fiber and other materials." Han Kuanbao, vice president of Nanjing Electric Bicycle Industry Association, said that the more protective the materials, the higher the price. A high-quality carbon fiber helmet can cost thousands or even tens of thousands of yuan. In addition to material differences, the coverage area of the helmet also has an important impact on safety. The protective effect of full helmet, but poor air permeability; 3/4 helmet gives consideration to both protection and breathability; Half helmet is easy to wear, but the ability to protect safety is poor; There is also a "lift up helmet" that can completely turn up the chin device, which is convenient to wear and has good protection.

Precautions for purchasing helmets: some of the foam cushioning materials for helmets have low density, which is even worse than the foam cushion for home appliances.

They will smell and soften when the sun shines, and may contain some toxic and harmful substances in the garbage during recycling. Because this kind of helmet is super cheap, many people buy it. For safety, we must not be greedy. The main certification standards for motorcycle foreign trade helmets: the United States, Canada, etc., DOT certification Europe, ECE certification.

The fiberglass shell can be made of any fiber reinforced material, including fiberglass, carbon fiber and aromatic polyamide. Different materials are constructed in different order, resulting in thin and hard shells. In these cases, the shell can be made thicker or thinner by increasing or reducing the number of material layers. The composite shell is high-density, which is why cheap helmets are made of peeling polycarbonate plastic. These housings are usually thicker and heavier than composite housings. The shell will usually withstand small impacts, such as falling from the seat when you park, without damaging your protection. Small bumps or scratches will not affect it. Anything more serious than a small bump will cause invisible damage, so you can return your helmet to the factory for inspection before you trust it. Any strong enough impact will end the service life of the helmet.
