Urban living gives you a great excuse to ditch your wheels and start taking advantage of your proximity to everything — but often you're not willing to rely entirely on the power of your legs to get you where you need to go. Greyp Bikes ($8,000) give you a choice, letting you use them as a bike when you want it, or a motorcycle when you need it. With a maximum speed of about 40 mph, and a range of almost 75 miles, it's the perfect vehicle for getting around the city, whether you choose to pedal, use battery power, or both. An LCD panel gives you all kinds of useful feedback, a fingerprint scanner lets you customize the experience and access for multiple riders, and the battery can reach a full charge in just under an hour and a half.
The BMW i8 ($136,000) provides an emphatic counterpoint to everyone out there who says a hybrid can't possibly be a fun car to drive — like it or not, this is the future. At its heart is a 1.5-liter turbocharged three-cylinder engine, capable of generating 231 horsepower and 236 pound-feet of torque. That power is delivered to the rear wheels through a six-speed automatic transmission. Up front an electric engine generates additional horsepower and torque, boosting the figures to 362 and 320 respectively. It'll get up to 62 mph in just 4.4 seconds, all while maintaining an average fuel economy of 94 mpg (which is nothing short of unbelievable). Oh, and the swan-winged coupe is absolutely gorgeous, but we didn't have to tell you that.
