Abstract: An overturning and folding device for a handlebar includes a tube (2) extending vertically from the handlebar base (13), a connecting member (15) next to the base (13), an eccentric axle (1) and a lug bolt (12). A first hole (21) in the axial direction and a second hole (20) in the perpendicular direction relative to the first hole are formed at the handlebar base (13) of said tube (2), which communicate with each other. The connecting member (15) is engaged to the fork of the bicycle, which defines a space (14) through which the lug bolt (12) can rotate from an axial position to a perpendicular position. The lug bolt (12) is fixed within the first hole (21) and space (14) by a fastener (8). The eccentric axle (1) is fitted rotatable in the second hole (20) and a third hole (5) on the head of the lug bolt (12).
