Motorcycle frame slider having elements of internal refraction and reflection

In a cycle having a bolt integrally secured to a cycle main frame or an engine block of the cycle, said bolt projecting transversely from said cycle relative to a vertical plane of symmetry thereof, a cycle frame slider comprising:

• (a) an elongate hollow cylinder having an internal diameter, an outside diameter and an annular region therebetween, said cylinder formed of a durable optically transmissible polymer, said cylinder having a proximal end and a distal end, said proximal end of said cylinder proportioned for securable engagement with said bolt, said cylinder having an axial length in a range of about 10 to about 15 centimeters;
• (b) a plurality of light-emitting means circumferentially secured within and about said proximal end of said hollow cylinder, said light-emitting means including means for control of on-off cycling and blinking thereof, said light-emitting means in optical communicating with said annular region of said cylinder;
• and
• (c) means for effecting electrical communication between said light-emitting means and a directional signal circuit of said cycle,
• whereby said axial length of said frame slider, in combination with said durable polymer, provides protection to the cycle in the event that it tips or falls over from a stationary position and, further whereby, superior cycle visibility and particular aesthetic effects are obtained by properties of internal reflection and refraction within said hollow cylinder by the operation of said light-emitting means in optical communication with said cylinder.
