The link above says cars but don't puke. It's actually another righteous write-up on electric dirt bikes complete w/video.
"The Zero X is an EV you can buy right now for $7,450. It weighs in at a bantamweight 150 pounds, delivers as much as 40 miles on a charge from a lithium-ion battery, and with a 23-horsepower motor it'll hit 57 mph (and throw up a big spray of dirt getting there). Sakai says it offers the same power as a 250-cc gasoline powered bike, and with 50 foot-pounds of torque it'll smoke the tires on pavement."
I think if they took more of a motard style approach, a nice quite electric bike would work well on the back streets and suburbs. I know I would much prefer something like this to a pocket bike or a moped.
