It's a Dillenger 36V, geared front hub motor kit about 4 - 5 years old (with a new battery). Price was $699, but now less expensive. Top speed 20 mph. ebikeling has a similar front hub kit for about $225 while a battery ranges from $200 - 400; recently I purchased (ebay) a 36V, 10 a/h battery and charger for $184 delivered from Unit Pack Power, a Chinese company, so a risky venture. Haven't had a chance to test it yet.
