Bike magazine has an awesome series called The Sh*t Bike Challenge. They take a softride bike (my bike is a softride) and give it to pro bikers to do various riding (cyclocross, trials, endurance races, downhill, etc.). In the last issue, the intent was to destroy the bike by setting it ablaze and flinging it with a trebuchet (catapult). Check out the results.
