Abstract: A bicycle handlebar includes a main body pivotally connected to a bicycle. A first holding portion and a second holding portion corresponding to the first holding portion are disposed at left and right sides of the main body. The first holding portion and the second holding portion each bend towards a forward riding direction and extend to form a forward bending portion. The forward bending portions each extend towards a backward riding direction to form a backward bending portion. The backward bending portions each extend towards the backward riding direction to form a rear section. A distance between the two backward bending portions is greater than a distance between the two forward bending portions, so as to expand a turning radius of the bicycle handlebar.

Abstract: A quick release attachment for a bicycle includes an attachment device, a bracket and a quick release assembly. The attachment device has a main connecting body. The main connecting body has a retaining groove. The bracket has a sub connecting body. The bracket has a connecting portion defined at one lateral side thereof. The connecting portion has an opening defined therethrough. The quick release assembly has a quick release member and an abutting block. The quick release member is assembled with the connecting portion and defines a tightening position and a releasing position. The abutting block is received in the opening of the bracket. When the pivot portion is on the tightening position, the abutting block is engaged with the retaining groove of the main connecting body so that the attachment device is secured to the bracket.
