Yea I used this forum as a bible when I put this thing together, I didn't want any failures I took my time and double checked everything. The motor was running fine, or so I thought up until it just died. I am hoping the place I got it from will at least send me a replacement at a discount price. If you haven't noticed yet I am unemployed and planned on using this to look for work, I used to be a auto mechanic so Im really good with mechanical stuff, there was no warning to this failure, I even checked that mag rotor bolt early in the build.That's the first time i've seen a magnet failure as described by your photos, and i've traveled over 30,000 miles in 3 & 1/2 years on my motorized bicycle in riding conditions from the good to the downright ugly.
I struggle to understand how such a magnet failure could happen given correct assembly of the parts?
