Brazilian Boombox bike via OOBject
We noted last fall that times being what they were, kids couldn't afford to cruise the streets in cars with the sound turned up, so they were customizing bikes. This turns out to be an entire subculture, with people annoying other people all over the world.
I love the way the woofers on this one look like rockets.
It looks rather sedate compared to the others, but over at Instructables you can build your own bike boombox, complete with plans a fifteen watt per channel amplifier.
