The limiting portion 14-2-1 has a first tapered surface for use with the positioning member 16, and anti-slip stripes are set on the outside of the anti-slip portion 14-2-2. The positioning member 16 is provided with a recessed platform 16-1 for connecting with the screw nut 14, and the recessed platform 16-1 is provided with a second tapered surface 16-1-1 that matches the first tapered surface. When the handlebar assembly is assembled with the front fork and frame assembly, it is completely fitted with the positioning member 16 mentioned below through the second tapered surface 16-1-1 and the first tapered surface to prevent the screw nut 14 from loosening. A positioning member 16 is provided on the handlebar 8 to form a handlebar assembly 15 . The positioning member 16 is fixed to the handlebar 8 and cannot be displaced in any direction on the handlebar 8 .
