Anak-anakbasikal are one of the main categories of children's basikal. Children's basikal include four categories: children's basikal, strollers, baby walkers, and children's tricycles. When buying a basikal, consider the age and height of the child, and choose the appropriate size, that is, a basikaldengan ketinggian pelana dalam julat 435-635mm. Semasa membeli kenderaan, perhatikan ukuran brek tangan. Sekiranya saiznya terlalu besar, anak tidak akan dapat memegang brek tangan dengan erat semasa melakukan brek, dan tidak akan dapat menghentikan kereta. Oleh itu, lebih baik bawa anak-anak anda mencubanya ketika membeli-belah. Di samping itu, daya brek tidak boleh kurang dari 50N. Jika tidak, kenderaan tidak akan dapat berhenti, menyebabkan bahaya kepada kanak-kanak. Anak-anakbasikal 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 basikal is indispensable. Children’s basikal 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.
