In 2000 adventurer Doug Stoup became the first American to ski from the Antarctic coast to the South Pole. But there was something wrong with the trip: it was too darn slow. So, working with bike designer and aerospace engineer Dan Hanebrink, Stoup came up with an alternative to skis: a bike that he could ride in Antarctica. The ice bike has no plastic parts (which would freeze and shatter in the extreme conditions), and the superfat, low-pressure tires provide traction in situations that would make a mountain bike weep. After a successful trial earlier this year, Stoup says he is ready to pedal to the Pole.
