We got to ride this yesterday. It has lithium batteries, has a lot of kick and goes 20 mph for 20 miles on one charge. It can carry an extra battery pack. It is also really comfortable, with its off-road frame, big tires and suspension. But it's neither a bike nor a motorcycle. It's some futuristic cross breed. It costs about $2700. Money aside, would ride one home?
You can buy these in only a few places. Here are some good links:
