per bambinibiciclette are one of the main categories of children's biciclette. Children's biciclette include four categories: children's biciclette, strollers, baby walkers, and children's tricycles. When buying a bicicletta, consider the age and height of the child, and choose the appropriate size, that is, a biciclettacon un'altezza della sella nell'intervallo di 435-635 mm. Quando si acquista un veicolo, prestare attenzione alle dimensioni del freno a mano. Se la taglia è troppo grande, il bambino non sarà in grado di tenere saldamente il freno a mano durante la frenata e non sarà in grado di fermare l'auto. Quindi è meglio portare i tuoi bambini a provarlo durante lo shopping. Inoltre, la forza frenante non deve essere inferiore a 50 N. In caso contrario, il veicolo non potrà fermarsi, causando danni ai bambini. per bambinibiciclette are also equipped with protective wheels (balance wheels), which can keep the rider in balance, so pay attention to whether they are equipped (one on each side) when purchasing. It is necessary to consider this. The chain cover of children’s biciclette is indispensable. Children’s biciclette with a saddle height equal to or greater than 560mm should be equipped with a chain cover or other protective device to cover the outer surface of the chain and the meshing part of the sprocket. When meshing on the sprocket, the chain cover should extend beyond the outer side of the chain in the diameter direction. If the chain cover is not used but other protective devices are used, the covering range should be extended to the point where the sprocket initially enters the two sides of the chain. Measure at least 25mm along the chain.
