Do not ride a bike down 8 Mile with Joyrider LEDs; you will die

There is absolute no way on this green earth that I would ride a bike with these LEDs on any street with the exception of maybe a deserted Montana road or in a sleepy Vermont town. Sure, the LED-powered wheels might bring a smile to some folks, but somehow I don’t think everyone is going to be smiling with you. The images come from a single LED device, dubbed the Joyrider, affixed to the spokes and controlled by microchips to correctly display the face, but the muggers aren’t going to care ’bout that when they are bashing your cheery face into the curb.
