Rocket-Powered Bike
Stored inside [Orion Propulsion's] portable trailer/workshop I found a bicycle that seemed to be nothing out of the ordinary, until I noticed the tank, pipes and frame behind the seat. Now, keep in mind that Orion does not build vehicles -- they specialize in rocket engine design, development and fabrication. Nevertheless, you have to have demos, so why not make them fun?
The two-wheeler is in fact the Rocket Bike. It does 0-55 mph in no time flat, and is powered by a very high tech fuel... roofing tar. Yes, ANN confirmed that the bike is powered by the same stuff it usually rolls over when moving. Add an igniter and more NOS, and off you go, triple-underwear and all.
Entertaining, but among the last things I'd like to see (which more or less guarantees that rocket-bikes will be everywhere in a year or so.)
