Greyp Bikes
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.
