A supporting frame includes a left supporting leg (1) and a right supporting leg (2). The left supporting leg comprises an upper connector (11) and a lower connector (12) which is connected with the upper connector through a joint structure (4). The lower connector can rotate under the joint structure thereby enabling the left supporting leg to be bended. A side supporting leg (3) is outwardly extended from one side of the left supporting leg. After the left supporting leg is bended through the joint structure, the side supporting leg and the right supporting leg form a side support to the riding vehicle. The supporting frame is provided with middle support and side support functions simultaneously. As a side support when in use, it only needs to provide the supporting frame of a forward force, so that the left supporting leg can be bended. As a middle support when in use, it only needs to raise the supporting frame slightly upwards, so that the upper and lower connectors can be engaged. The supporting frame provides a convenient operation while has the advantage of saving labor.
