Cars are about as hard on your bank account as they are on the environment. Buying a gas-guzzler not only costs you up front but also sets you back more than $8,500 a year for gas and maintenance. In 2010, the average U.S. commute was less than 13 miles, so consider trading in your car for a bicycle, or one of these wheeled gizmos. Your wallet—and the air—will heave a sigh of relief.

Kyle Doerksen, a snowboarder from the Canadian Rockies, didn't want his powder sessions to end when he left the slopes, so he dreamed up the ultra-smooth-riding ONEWHEEL. It's a battery-run wonder that tackles up to eight miles of any terrain—wet sidewalk, grass, trail, or sand—per 25-minute charge. The self-balancing Onewheel is water-resistant, durable, and equipped with a rugged go-kart tire. Yeah, it's pricey, but that's because it won't explode, unlike some of the cheaper electric boards. $1,499, onewheel.com

Most skateboard decks are made from maple, but BAMBOO SKATEBOARDS' 32-inch Rasta Tiki Bat Tail Longboard is 70 percent bamboo, a fast-growing plant that requires half the time to produce that wood does. Bamboo's flexible nature makes this cruiser comfier. And since longboards are more stable than typical boards, the Bat Tail is easier to ride. Use this seven-pound rig to surf asphalt to work, then stash it upright beside your desk. $169, bambooskateboards.com

Thanks to its 350-watt, battery-powered motor, the aluminum bicycle can cruise a breezy 20 miles per hour. The handlebar displays the battery level—so you know when to head toward a plug—and lets you choose how much engine help you want. This single-speed also has an LED light-up front and a steel-frame rack in the caboose. $999, electrobike.com
