A bicycle wheel securing structure includes a shaft member, a head member, a lever member and an adjustment member. The shaft member has a first threaded end and a second end with a center axis extending therebetween. The head member is disposed on the second end of the shaft member. The lever member is operatively mounted between the shaft member and the head member to move the shaft member in an axial direction relative to the head member in response to movement of the lever member. The adjustment member is axially adjustably coupled to the head member such that an axial position of an abutment surface of the adjustment member can be adjusted relative to the shaft member.
