New description: [New technical field] This creation is related to the bicycle frame, especially for a self-cultivating frame. [Prior Art] The frame of a traditional bicycle is made up of 40% of metal material, which is heavier. In order to reduce the weight of the frame, in recent years, a frame made of stone anti-fiber reinforcing resin has been developed, and the frame includes a tube, a tr, a lower tube, a riser, a second rear upper tube, and two a rear lower fork pipe and a portion, wherein the head pipe, the front end of the upper pipe and the inner end of the front end of the lower pipe are connected to and/or (10) into a front end of the copper pipe - the vertical pipe connected to the front fork Its t:: the top of the cum tube is fixed with a - handle, and the fork of the fork has a front wheel. , bicycle process towel 'When the controller controls the Wei hand to turn ==:: When the grip is used for braking, the front of the frame will be subjected to great stress, and structural damage often occurs after long-term use. The strength of the fabric increases the amount of carbon fiber reinforced resin, so that the circumferential force of the front of the car: thick, and will increase the weight of the bicycle frame, making the rider more laborious. Therefore, the combination of the amount of (four) and the structural strength of the front of the car has reduced the research and development issues that the industry needs to solve. [New content] The main purpose of this creation is to provide a bicycle frame, which has better structural strength and light weight. In order to achieve the above object, the reinforced bicycle frame of the present invention is made of fiber reinforced material, and the reinforced frame includes a head pipe, an upper pipe section, a lower section and at least one rib. The upper pipe section is extended from the head pipe. The lower pipe section is integrally extended rearward from the head pipe and the 1 is located below the upper pipe section, and the copper pipe, the upper f section and the inner part of the lower pipe section are connected to each other and are connected to each other. The fresh, rainbow pipe section and the inner surface of the lower pipe section together form a silk surface, and a chamber defined by the inner surface. The rib has a connecting end connected to the inner surface of the head, and a free end remote from the connecting end is located in the head A of the head. [Embodiment] The following is a list of preferred embodiments and in order to better understand the features of the present invention, with reference to the drawings, wherein: the first drawing is a front view of the first preferred embodiment of the present invention; A partial perspective view of a preferred embodiment of the present invention.
