Rocket Bike!

post #1 of 6

Enough thrust to smoke a Porsche off the starting line? Check.
Crash Helmet? Check.
Brakes? Umm...
Darwin Award nomination form?...

How It Works
1. A toggle switch on the battery pack arms the ignition system.
2. The left-thumb button sends power from the battery pack to an igniter on a model-rocket motor inside the rocket engine, vaporizing the roofing-tar fuel so it can burn.
3. The right-thumb button keeps the nitrous oxide flowing (and the rocket lit) as long as it's pushed.
4. The left brake lever regulates the flow of nitrous and throttles the rocket.

For rocket designer Tim Pickens, a rocket on two wheels is the next best thing to a spaceship. "At heart we're a bunch of guys wanting to go to space, and we can't afford it," says Pickens of himself and his rocket-scientist brethren, most of whom never get to ride their own creations. "Basically it's my own subscale space program."

Pickens, president of rocket-design firm Orion Propulsion, created his first rocket bike with fellow speed enthusiast Glenn May by bolting a 35-pound-thrust rocket engine to Pickens's bike -- enough power for a gentle push down the road.

That project didn't kill anyone, so Pickens got himself another bike and stepped it up, attaching a 200-pound-thrust engine capable of blasting him from 0 to 60 miles an hour in five seconds -- fast enough to beat a Porsche in a drag race.

The rocket bike employs the same hybrid rocket technology as the suborbital rocket plane SpaceShipOne, whose propulsion system Pickens helped design.

In place of synthetic rubber fuel, however, the bike uses ordinary roofing tar. To ignite it, Pickens placed a model-rocket motor inside the engine. A button on the handlebar fires the model-rocket motor, which in turn sets off Pickens's larger motor by lighting the roofing-tar fuel.

His next project is to build a company car: a pickup truck with a removable 2,000-pound-thrust rocket strapped into the bed.

Holy Poached Pillion Passenger, Batman!

While you wouldn't necessarily want to ride behind this guy, the look on the face of the sticker/neon/whaletail boy racer challenging him might be worth the scorchmarks. The challenge would probably be not to fall off the thing laughing at their OMGWTF!??1! expression.

Expect to see X-Games competitors queueing up to buy these things.

I'd also think a few bicycle cops might be interested in them as a "pursuit" model.

Redneck DIY folks/Blazing Saddles fans may try the 'blue flame' version after mucho baked beans, but this seems so much more impressive.

Um, from the looks of the picture, I hate to think about where the fuel is coming from... *GULP*.

Yes. The black cylinder is just a burn chamber

Well, it is Tar powered, so logically what's missing for the ramp trick are Feathers.

A sportbike -- even a smaller one -- is still much more dangerous.
