I put this bike together with a Nine Continent kit (2806 hub, 20A Infineon controller, twist throttle) and eZee 36 volt 9 Ah lithium battery. I have put very few km on it. Fun and fast to ride. Rider controls electric boost via a motorcycle-type twist grip. Frame is a 23" Nishiki with new road tires which work well on the gravel sections of the Lochside trail. Comes complete with battery charger. I have invested over $1,500 into this bike.
