For a Light Cycle I'd go with:
1 Roll of Duct Tape
6 AA Batteries
6 LED (color mixed)
6' Speaker Wire
Place the batteries at the inner most core of the rim, wrapping the wire around the spokes reaching to the outer portion of the rim, there connecting the LEDs, and using the Duct-Tape as required to keep all items in place.
With this Handy-Dandy Light-Cycle, YOU TOO could be the talk of the town while you ride here and there, drinking water from your favorite empty alcoholic container, and inspiring your biology to actually require nurtrients.
Who knows, maybe after spending some real quality time with your new "Jedi Cycle", you may garner enough motivation to hit the gym in search of your natural peak, and then require those magical things called "Steroids".
