Abstract

The invention discloses a folding bicycle frame and a bicycle frame folding method. The folding bicycle frame comprises a bicycle frame main body, a rear wheel frame, a stand and a locking element. The rear wheel frame is movably connected with the bicycle frame main body through a first hinge shaft. The locking element is arranged on the bicycle frame main body. The rear wheel frame is provided with a locking-fixing part. The locking element is provided with a locking part. The rear wheel frame is provided with a support position and a folding position. When located in the support position, the rear wheel frame is locked by the locking part and the locking-fixing part which are opposite. When the locking part leaves the locking-fixing part, the rear wheel frame is located in the folding position. The stand is movably connected with the bicycle frame main body through a second hinge shaft and provided with a support position, a folding position and a locking prodding part. When the stand is located in the folding position, the locking prodding part gets far away from the locking element. When the stand is located in the support position, the locking prodding part gets close to the locking element. According to the folding bicycle frame and the bicycle frame folding method, operation is more convenient, and safety is higher.
