Controller installation: The upgrade is a mostly straightforward and easy operation. You just take off the motor cover and the plastic cover under the chainring. Then you can see the controller and the rest is fairly obvious. The only part that is a little bit tricky is prying out the rubber plug around the cables where they pass through a hole in the motor body. Here is a video showing how to remove it. https://www.youtube.com/watch?v=Wb8Omk6e7GI from 2:30 to 4:20.
