Abstract: A safety-reflector device universally adaptive to spoke wheeled vehicles such as bicycles; said reflector being suitably streamlined and attractive in appearence while functioning to create a visual cyclodial pattern of highly identifiable movement during normal wheel rotation under night-time use conditions; said reflector having unique captive attachment means via rotation of wafer-like half sections about a common interconnecting point as may be centered between any two adjacent spoke members, with elongated ends overlaping thus captive spokes.
