Meet our future best friends and road buddies: the Richmond Hill, Queens teenagers who pimp their bikes with 5,000 watt stereo systems. Looking at these photos, they've defied the laws of physics and reason. We have enough trouble keeping our tires from going flat, the idea of putting a 50-lb stereo on the back of our bikes seems as impossible as time travel. It's like the Wright Brothers of bike cruising, and we imagine that, by next week, the musical bikes will take flight.
