The Skycycle X-2 was a steam-powered rocket owned by Evel Knievel and flown during his Snake River Canyon jump in Idaho in 1974.
An earlier prototype, the Skycycle X-1 designed by Doug Malewicki and retired U.S. Navy engineer Robert Truax, superficially resembled a motorcycle. It was tested in November 1973 and dove in the Snake River.
The Skycycle X-2 was designed by Truax, and ridden by Knievel in his attempt to jump the Snake River near Twin Falls on September 8, 1974. The parachute deployed during the launch, causing the stunt to fail.
A later analysis showed that a design flaw in a mechanical parachute retention cover, which did not properly take base drag into account, caused the premature parachute deployment. Following the failed jump, Truax blamed Knievel for the failure and vice versa. Later Truax accepted full responsibility for the failure.
Although the parachute deployed early, the aerial photographs show the X-2 cleared the canyon. However, the winds blew the rocket back to launch side, crashing at the bottom of the canyon, barely missing the river. Knievel stated that if the X-2 had landed in the water, he would have drowned, as he did not have the ability to release himself from the harness.
In order to obtain permission from the State of Idaho to perform the canyon jump, the X-2 was registered as an airplane rather than a motorcycle.
Three X-2 Skycycles were built for Knievel. The first two were used for test flights. Unable to fund further tests, Knievel used the third for the canyon jump. In 2007, the X-2-1 Skycycle was offered for sale for $5 million. The X-2-2 is owned by the Knievel estate and periodically exhibited along with a museum of Knievel artifacts.
In the era before cable networks, the Sunday afternoon jump was covered live by Top Rank on paid closed circuit television in several hundred theaters and arenas, promoted by Bob Arum with an average price of ten dollars. Taped coverage by ABC was shown on Wide World of Sports later in the month. The ticket price at the launch site was twenty-five dollars.
