World’s Fastest Speed On A Bicycle? [VIDEO]

Have you ever wondered what the world's fastest speed is on a bicycle?  We're talking human-powered speed over flat terrain. It's an unbelievable 82.3 miles per hour!  Canadian Sam Whittingham achieved the feat in 2008 over a flat stretch of road in Nevada.  And as you'll see in the video below, it wasn't on anybody's idea of a conventional bike.  Of course, the carbon fiber shell serves to cut wind drag, but it also protects the rider in case of a fall.  If you're a cyclist, you know that anything over about 35 miles per hour is REALLY fast on two narrow wheels.  I love to ride.  But 82 mph?  Watch Sam in action below:
