My roommate just bought one on 2008-04-19, a low cost 250 watt model from
GWEV (Green World Electric Vehicles), similar to the one in the picture. Most models
are twice as powerful. Of course I got to ride it.

The bike has a rated range of 30 km (18.64 miles) More expensive models are in the range of 80 km (49.71 miles). I would expect it depends just how much you use the assist. You plug the bike into the wall to charge any time it is not in use, and the charger automatically shuts off when the cells are fully charged.
This one is fitted with a large front carrying basket and two detachable saddle bags in the rear. Its main function will be fetching groceries.
It’s fun to pass a long line of cars by zipping along the bike lane. It is fun to seriously out-accelerate the cars at an intersection. That you can do that might come as a surprise. Newton discovered that acceleration = force / mass . This means you can double the acceleration by doubling the torque of your engine or by cutting your vehicle’s gross weight in half. An electric bike weighs a tiny fraction of a car, hence runs circles around it in acceleration.
