I try to run 36v LiFePo4. I am a commuter rider, so not wanting to run faster than 25, but I like to get off the line fast and be able to climb walls.
Right now I am pulling about 1300w tops from my pack, but I know I have some inefficiencies in my set-up that is sucking a bunch of that up.
Also, it looks as though you are using a freewheel on both sides of the motor. Is this necessary? It seems like one on the crank side is enough since the rear wheel will have a freewheel on it. Could you not use a fixed gear on the output side of the motor?
I have been thinking of ways to use #219 cart chain in a mid-drive setup and it seems like using a fixed gear on the output side of the motor and one of the crossfire 10-hole freewheels on the back (I'm using Nuvinci hub) would be a good solution for using #219.
