The Monkey Light 8-Bit Bike Wheel Light is just a lovely piece of awesome. The battery pack straps to your bike wheel’s hub (so it doesn’t mess up the balance) and the light unit quickly installs near the tire. With a few button presses, you’re selecting one of 20 different light patterns which will blast out of both sides of your tire (5 super-bright LEDs per side). $49.99
And then you get to select the colors you want (each theme has many color options). Finally, use science (persistence of vision) and your own muscles (pedaling power) to turn 10 spots of light into awesome streaking patterns. Skulls, invaders from space, rocket ships, fiery comets, and 16 more!
