어린이용 보조 바퀴자전거양쪽의 높이가 같고 모두 지면에서 약간 떨어져 있습니다.

어린이용자전거 are one of the main categories of children's 자전거. Children's 자전거 include four categories: children's 자전거, strollers, baby walkers, and children's tricycles. When buying a 자전거, consider the age and height of the child, and choose the appropriate size, that is, a 자전거435-635mm 범위의 안장 높이. 차량을 구입할 때 핸드 브레이크의 크기에주의하십시오. 사이즈가 너무 크면 아이가 브레이크를 밟을 때 핸드브레이크를 꽉 쥐지 못하고 차를 멈출 수 없게 됩니다. 따라서 쇼핑할 때 자녀와 함께 사용해보는 것이 가장 좋습니다. 또한 제동력은 50N 이상이어야 합니다. 그렇지 않으면 차량이 멈출 수 없어 어린이에게 피해를 줄 수 있습니다. 어린이자전거 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 자전거 is indispensable. Children’s 자전거 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.
