Abstract
A child's swaying bike includes a seat, two rear rollers, a center rod, two front rollers, and a handlebar. The bike can move forward by swaying of the center rod to the right and the left. The handlebar can be pivotally connected quickly with the center rod by inserting a pivot to simplify the structure of the child's swaying bike. The handlebar has an intermediate horizontal potion and two L-shaped side portions extending from the two ends of the intermediate horizontal portion. The two L-shaped side portions are symmetrically positioned to let a child ride and sway safely and stably on the seat, designed to conform to ergonomics.
