Using Toshiba's quick-charging lithium ion rechargeable battery, the power-assisted bike from Cannondale Sports Group LLC was exhibited at a New York auto exhibit. The bicycle can run about 20 to 30 miles per charge. It's set to release in North America and Europe on 2009. Because the ratio for the force for the motor and the legs is 1:1(meaning 50% by the machine and 50% by the legs), the bike will unlikely be released in Japan, where the maximum ratio of the motor force to legs is 2:1.
