I am going to use this thread to document the mid-drive eBike conversion to my custom-built pedal-pushing Nashbar mtn bike. Truth be told, ‘custom‘ is used loosely here - other than the frame, I only needed a top-pull front derailleur to complete the ‘customization’ from the donor bike, an Ibex Ignition II I bought in 2005. The Nashbar frame I purchased in late 2000’s for about $150. At the time the Ibex had a leaking rear shock and I wanted the lighter weight of a hard tail. The resulting Nashbar bike has been an excellent all a-rounder; it should handle the power of the Bafang BBSHD motor I want to install. Besides, I don't ride hard and I don’t intend to ride single-track trails.
Note: I still have the Ibex dual-suspension frame and may decide to build it back up with a mid-drive kit as well one day.
