Choosing the right kids' bike and helmet選擇合適的兒童單車、頭盔
選擇兒童單車主要考慮是兒童身高
適合12歲或身高1.5米以下的小童，車呔直徑一般為10至24吋。
兒童兩歲起又達到85厘米至1米身高可先考慮從平衡車開始，
這樣會較容易學會平衡，掌控單車的速度和正確地把單車剎停。
若小孩身高達90厘米或以上，可為他們選擇14吋（約3至5歲）的兒童單車附有輔助轆或16吋兒童單車及加購輔助轆（約4至6歲）或20吋兒童單車（約6至8歲），
甚至是24吋兒童單車（9至12歲）。
The main consideration in choosing a children's bike is the height of the child
Suitable for children under 12 years old or 1.5 meters tall, the diameter of the tie is generally 10 to 24 inches.
Children who are 85cm to 1m tall from the age of 2 can start with a balance bike.
This will make it easier for children to learn to balance, control the speed of the bike and stop the bike properly.
If children are 90 cm or taller, they can choose a 14" (age 3 to 5) children's bike with assisted rolls or a 16" children's bike with additional assisted rolls (age 4 to 6) or a 20" children's bike (age 6 to 8).
Or even 24-inch children's bicycle (age 9 to 12).
二、如何選擇合適的兒童頭盔？
為了頭盔達到最佳保護效果，建議您在耳朵上方用捲尺測量孩子的頭圍。
在設計頭盔時，這是大多數測量的目的。
如果您沒有靈活的捲尺，請使用一根繩子，然後測量它的長度，可參考以下圖片。
