Abstract: The utility model discloses an improved bicycle handlebar, including a handlebar tube and a handlebar head. The handlebar head includes a curved arm and grips. The curved arm is of a structure that inclines forward relative to the handlebar tube. The grips naturally stretch along two ends of the curved arm toward the left and right sides. The handlebar tube is provided with a positioning groove and a limiting hole, a support tube is provided with a positioning protruding portion. After the handlebar tube is inserted into the support tube, the positioning protruding portion is inserted into the positioning groove to ensure that the handlebar will not rotate by itself. Screw the limit screw into the limiting hole to prevent the handlebar from being too deep to pull out. The handlebar is designed to be of a structure, which is more comfortable to use.

Abstract: The present invention relates to the field of electric bicycles, and in particular, to an anti-theft battery box structure for an electric bicycle. An external structural shape of the anti-theft battery box structure matches a shape of a top tube of a frame, so that the anti-theft battery box structure and the top tube form a whole to keep the complete appearance of a bicycle. A controller is disposed at a lower end on a rear side of the top tube, and a control box presents an inverted triangle, so that the frame has a more stable structure. In addition, a bolt of a battery lock can enter a lock hole of a battery box, to achieve an anti-theft effect.
