• the upper pipe and the lower pipe are disposed such that an interval in the up-down direction increases toward a front side of the balance bike,
• the rear frame includes an extension member that is a separate member from the front frame and extends in a front-rear direction,
• the main frame includes a connecting member to which the rear end of the front frame and a front end of the extension member are each joined,
