The rocket was manufactured by Swiss company Exotic Thermo Engineering according to Gissy’s specifications. Concentrated liquid hydrogen peroxide is mixed with a catalyst, typically silver, which causes it to decompose into heat, water (steam) and oxygen. The steam provides thrust as it is forced through a rocket nozzle.

Although Gissy beat the record of 2002 he missed the overall cycling speed record set by 50-year-old Dutch cyclist Fred Rompelberg in 1995. He pedaled in the slipstream of a dragster in Utah, USA, and reached a speed of 268.8 kilometers per hour. He was provided with considerable help by the slipstreaming effect of the lead vehicle.
