A balance bike includes a frame, front and rear wheels, a seat, a joining structure, a front fork, and a steering handle. The joining structure is pivotally joined to the frame and pivotal between first and second positions. The joining structure includes a joining end and a receiving end. The front and rear wheels are disposed apart from each other, and the balance bike defines a first longitudinal dimension when the joining structure is in the first position. The front and rear wheels are disposed adjacent to each other, and the balance bike defines a second longitudinal dimension when the joining structure is in the second position. The first longitudinal dimension is larger than the second longitudinal dimension.
