Your choice of rear hub motor is excellent for a direct drive system. Don't know where you're located, but if US, look at Luna Cycle for battery. You'll need to get an extra set of connectors for the battery and your controller. If you're frame is aluminum (assume it's 26" wheels), look at Grin (on Amazon) for a torque arm. Put 48V, 1000w into your browser and get basically same kit for less at accesseries or whatever.
