At present, there are many brands and models of children’s bicycles sold in supermarkets and shopping malls in some big cities, but many of them have problems such as exposed chains, no protective wheels, too high saddles, and only one brake.
Regarding the safety hazards of children’s bicycles, relevant experts pointed out that between the brake lever and the handle of the children’s bicycle, if the size of the brake lever is too large, the child will not be able to hold it tightly and will not be able to stop the car. The chain of a children’s bicycle is not covered by a full chain box. In fact, the designer did not consider the special needs of children, and safety hazards are inevitable.
The international standard of bicycle factories on the “safety requirements for children’s bicycles” stipulates that the braking force (ie braking force) shall not be less than 50 Newtons. However, some of our children’s bicycles actually only have one brake, which simply fails to meet the requirements. International standards also stipulate for children’s bicycles: the maximum height of the saddle is 560 mm or higher, and it should be equipped with two independent braking systems (ie, brakes), one on the front wheel and the other on the rear wheel. Experts pointed out that although higher technical requirements are put forward for the braking system of children’s bicycles for the safety of riding, some children’s bicycles are not fully implemented in accordance with this standard, and the harm to children’s riding safety is Obviously, this should arouse the attention of relevant parties.
