Biking is a fine way to get exercise while enjoying the great outdoors, but there's nothing worse than pedaling miles from home, then realizing that you're going to have to pedal all the way back too. While it looks like a standard cruiser style bike, the Twist Freedom DX from Taiwanese bike manufacturer Giant, hides a 250 W DC motor, that can propel the bike up to 75 miles. A selector on the handlebars lets you choose how much human power you want provide, then the electric motor delivers the rest. Just the thing you want when you're miles from home and it's getting dark.

It will be available in May for about $2000.
