Gadgets to die for

Forget racetrack-worthy sports cars. The eco-conscious Silicon Valley crowd is getting revved up about Electrobike's Pi, a Ferrari-red, electric bicycle worthy of being parked beside the SLR McLaren Roadsters at the Sharon Heights Golf and Country Club.

The makers of the Pi, which weighs less than 60 pounds, like to tout the bike as a "human-electric hybrid," since it can be propelled by both pedal power and a 36-volt nickel metal hydride battery that's hidden inside the Pi's elegant monocoque arch frame. The battery power alone is enough to take the two-wheeler a distance of 25 miles at speeds up to 20 mph.

A single charge can carry dealmakers between their Atherton homes, Sand Hill Road offices and lunch meetings at Buck's in Woodside without any legwork. A little pedaling will extend the zero-emission bike's range, and an extra battery pack can transport riders an additional 25 miles -- say to meetings at the ultra-green Googleplex.
