Install: Bafang BBSD HD 1000w Mid-drive electric assist motor on a Madsen Family Cargo Bucket Bike

Testing Madsen Bucket Bike without mid-drive motor. Went great on relatively flat streets even with two kids but we live in a  hilly town in Vermont. 
I'll be documenting the installation of a mid-drive electric assist motor on my wife's new Madsen Bucket bike here.

The Box! Assembly is very easy, basically putting on the front wheel and a fender.

 Here's the manual, a list of different builds with motors like this. 



Working on the rest now.
