The kit comes with the motor already laced to rim so setting it up is easy. They supply the motor in various power from 200W to 500W, 24volt to 48 volt, and rims from 16 inch, 20inch, 24inch and 26inch.
That is what I did. I was thinking that sometime in the future I would like to try a Nuvinci rear hub. I did have to replace the aluminum shock fork with a steel solid fork.
