Giant Twist Freedom DX

Go green and get some exercise with the Giant Twist Freedom DX ($2,000; May). This electric bike offers users a choice between using battery power, pedal power, or a mix of the two. It sports dual 26-volt lithium-ion batteries, which offer a range of up to 75 miles per charge, depending on how much your lazy butt wants to pedal. An integrated torque sensor keeps things running smoothly, while a cushioned seat keeps you comfortable throughout your commute. [via]
