It's this motor http://www.bmsbattery.com/ebike-kits...-bike-kit.html. I don't know what brand the motor is but bms calls it a Q128. I'm not emotionally invested in that particular motor but I like the bms bottle battery so I thought I might save a little on shipping to buy both from bms. Anyone care to recommend a different 36v/500w+ motor for my build. I need to go front drive to keep my 8sp internal geared rear hub.
