Summer is here, and we have the perfect way to help you get in shape—a Space Cruiser! No, we're not going to be sending you into orbit anytime soon—we're talking about a Paul Frank Space Cruiser bike. We're giving one lucky winner one of these fabulous bikes to jumpstart your summer weight-loss program.

Adopting a healthy vegetarian diet is one of the best things that you can do for the planet and your waistline, but you can enhance the benefits to both by leaving the keys behind and getting a little cardio on your way to the grocery store, while running errands, or while going wherever your flip flops take you this summer.

According to a 2006 U.N. report, the meat industry produces more greenhouse-gas emissions than all the cars, trucks, planes, and ships in the world combined—providing further evidence that meat's not green. So by adopting a healthy vegetarian diet, leaving your car parked, and using this awesome bike, you'll be preventing the release of thousands of pounds of carbon dioxide into the atmosphere—and speaking of pounds, you'll also be doing yourself a favor by getting into shape!

Paul Frank makes some pretty awesome bikes, but the company also has a serious love for dogs and the environment. Not only are Paul Frank employees able to bring their dogs to work, CEO John Oswald also had a dog park built to keep the dogs entertained while their human companions are hard at work coming up with all sorts of new products—like the new Space Cruiser. This is just one of the seven new Paul Frank bikes released for summer 2009. And in case you're wondering, Paul Frank bikes are vegan. The company does not use leather to make any of its bikes.
