ABSTRACT:
A bicycle spoke warning light device capable of setting and displaying characters. The device is mounted on the spoke of the bicycle, in which a rotational speed detecting unit of a controlling circuit detects the rotational speed of the spoke. When the rotational speed reaches a certain value, a processor takes out the data set in a memory unit by a setting unit and makes multiple light sources immediately emit light to form a predetermined picture or character on the quickly rotating spoke by using temporarily remaining vision so as to achieve a highlighting and warning effect.
