Two Wheels, Zero Emissions and Loads of Fun By Chuck Squatriglia August 20, 2008 | 4:07:09 PMCategories: Electric Vehicles, Motorcycles Ask Neil Saiki why he designed an all-electric motocross motorcycle and he'll tell you EVs are the future, dirt riders must be more environmentally responsible and the sport faces a shaky future because dirt bikes are so loud they'll make your ears ring. That's all true, but push him a little and he'll confess the truth. "I love to ride. That's the real reason I did it," he told us with a laugh. "I wanted to make a product that's crazy fast and fun to ride." The Zero X from Zero Motorcycles is an EV you can actually buy right now for $7,450, and it's a real motorcycle. It weighs a bantamweight 140 pounds with the lithium-ion battery, and with a 23-horsepower motor it'll hit 57 mph and leave a fat streak of rubber on the pavement getting there. Saiki says the street version coming next year will be even quicker. Saiki started developing the Zero X five years ago after participating in a NASA round table analyzing transportation technology. He became convinced electric drivetrains are the best way forward and motorcycles the logical place to develop them. They're smaller and less complex than cars, and the regulatory hurdles to getting them on the road aren't as high. Off-road bikes lend themselves to electric power because they're typically ridden short distances, so range isn't that big an issue. Electric motors also provide gobs or torque, a big plus in motocross riding. The Zero X produces power instantaneously, and it'll catch you off guard because the bike is all but silent. Snap the throttle too hard and you'll lift the front wheel. "The throttle is like a light switch," Saiki says. "It's on or it's off." A low-speed mode limits the bike to about 30 mph and is good for tooling around. Switch to high-speed mode and you get unfettered acceleration to about 57 mph. The Zero X will hit 30 mph in under two seconds and 57 in about twice that. Juice comes from a proprietary li-ion battery that weighs 40 pounds and provides about two hours of riding time. It recharges in about two hours using any household socket, and you can get a spare for $2,950. The Zero X has hydraulic disc brakes and fully adjustable suspension with about 8 inches of travel. It looks a bit like a big mountain bike, which isn't a coincidence. Saiki, who holds a degree in aerospace engineering, has designed bicycles for Santa Cruz, Haro and Mountain Cycles. He worked through seven prototypes and designed most of the 300 or so components himself. The bikes are built in a factory near Santa Cruz, and Saiki hopes to turn out 300 a month by next summer. He's sold 127 since April (Google's Larry Page bought three) and has a waiting list of 77 people, including two guys who signed up after seeing the bike outside our office. Saiki says about 75 percent of buyers are seasoned motocross riders, which speaks to the bike's dirt cred. Saiki had motocross hall-of-famer Jeff Emig flog a prototype at a track in Las Vegas last year, and Emig says it's the real deal. "I'm expecting the production version to have a huge impact on the motor sports industry," he says. We probably won't see James Stewart or Ryan Villopoto racing them anytime soon (although Saiki says the AMA is interested in racing e-bikes) but the guys at Dirt Rider (.pdf) called an early prototype of the Zero X "the inevitable sound of the future of off-road motorcycle riding." As for Zero Motorcycle's future, it includes a street version good for 70 mph and a range of 60 miles. Look for it in January with a sticker price of $9,000.

I wouldn't want to be riding this thing when the battery blows up and catches on fire. The Dell notebooks that blew up used the same type of battery, lithium-ion. But if Larry Page is on it when it happens then ... :)
