power settings to place more emphasis on muscle or motor. Motion Measure:
The torque sensor tells the 250-watt DC motor how much power it needs to
supplement your pedaling. Dual Charge: A pair of 26-volt lithium-ion
batteries help power you up to 75 miles.
While electric bikes have been growing in popularity, they are typically
hampered by paltry ranges resulting from limited battery life. Because the
Giant Twist Freedom DX ($2000) runs on a cyborg like mix of muscle and
machine power, it can travel twice as far as most powered cycles-up to 75
miles per charge.
When you pedal, an integrated torque sensor summons the perfect amount of
power from the bike's front-hub motor to keep you at a steady pace; pedal
harder and the motor settles down, take a rest and it kicks into overdrive.
The bike comes out in May, and the manufacturer tells PM that it sees the
technology eventually taking off in developing countries, where it could act
as a low-cost option for carless commuters.

This article is very interesting. I would be tempted to buy one but the
price of USD2,000 is a bit too steep for me.
