Convert your bicycle from man-power to horsepower with the RevoPower ($600; 2008). The wheel, which weighs in at under 15 pounds and is designed to fit most bikes, contains a 21cc motor that gets over 100mpg and goes around 17mph. A simple way to power up your commute. [Thanks. Cliff]
If you don't care for those pesky "motors" that they're putting on boats these days, you should check out the Escapade Pedal Boat ($3,500). Its leg-powered, 15-inch two-blade propeller and rotomolded polyethylene hull glides smoothly through any body of water — from shallow canals to the Atlantic. With room for up to three drunkards, the boat sports a protective windshield and high freeboards, built-in bilge pump, collapsible polyester bimini top, and a dry shelf for towels, cameras, and the like.
Kawasaki brings their experience in winning IJSBA championships into the design of their new Jet Ski Ultra 250X ($11,500). The most powerful production personal watercraft made, this Jet Ski gives riders 250 horsepower from its 1,498cc marine engine. Speaking of the engine, it has a direct-drive supercharger and a large capacity intercooler to help you speed down the waterways as you bounce along on the race-developed hull while gripping the five-step adjustable handlebar.
