A bicycle helmet having a body (22), which preferably includes both a base (24) and a reinforcement structure (100). In one arrangement, the reinforcement structure is an external shell and, in another arrangement, the reinforcement structure is an internal skeletal frame. In some arrangements, the helmet body may include both an external shell and an internal frame. The helmet also includes a retention mechanism (30) defining a contact surface configured to contact a rearward surface of the head of the user. A strap arrangement (40) includes a first strap portion (44) and second strap portion (46) selectively connectable to one another to extend from opposing sides of the body and underneath a chin of the user. Desirably, no portion of the strap arrangement (48) is secured to the retention mechanism (30). The strap arrangement includes a strap section extending through a pair of spaced openings in a lower, rearward portion of the body such that a portion of the strap section extends across an outer surface of the body between the openings. Preferably, each of the openings is sized and shaped to generally correspond with a cross-sectional size and shape of the strap section.
