Ok, here's the starting point. A stock inexpensive aluminum frame fatbike. I decided the ultra motor would be a bit more refined than a BBHD (torque sensing and power) for this build. One of the biggest challenges I see that people have is attaching the Ultra motor assembly to an existing frame...Without panic. How does one go about making it fit like it was designed for the frame? How do you align the chain line? Will the bottom bracket be in the same location as factory? Follow along and see how I "cheated" on some of these issues.
