Rode an EG Maui, 28 mph PAS (20 mph throttle), 48V, 500w Dapu rear-hub motor (reportedly made in Japan) for a short time. This bike accelerated to 25 mph as fast as any of the 10 or so 500w bikes that I've ridden. Was so impressed with it that when my friend visited from norcal I suggested that she purchase one, and she loves it. If I were looking for a commuter this would be at the top of my performance/price list. She plans to commute as well as ride it on dirt roads (trails?) at home.
