Abstract (en)
[origin: WO9859333A1] A bicycle wheel (4) is supported by a fork (6) to which a magnet (12) is attached. Attached to one spoke (8) of the wheel (4) is an elongate array (10) comprising sixteen light emitting diodes extending radially of the wheel (4). A controller (16), mounted on the spoke (8) is connected to the array (10) by a cable (18). The controller includes a memory that stores a program for controlling the sequence in which the different LEDs of the array are to be energised. By selecting the timing and energisation of the different LEDs in accordance with a predetermined program, the observer will see an apparently stationary image on the wheel notwithstanding that it is rotating.
