Street Smart hybrid electric bicycle

Last weekend I went to Street Smart San Diego where, among many interesting booths, they offered test rides of various hybrid electric bicycles. I really liked the Eneloop from Sanyo which is coming to the U.S. this Fall. It's not just an electric assisted bicycle (in the spirit of "mild hybrid" automobiles) but a hybrid integrated drive (in the spirit of Toyota's hybrid synergy drive. You don't have to think about controlling the electric motor. The way you ask for power is to pedal, and the bike matches your effort 2-to-1 at low speeds and 1-to-1 at high speeds. Coast on a slight downhill and it reclaims some energy to recharge the battery. Brake and it reclaims more.
