Alot of torque might be an understatement.

I googled and came up with kollmorgen/danaher. Didn't look like the K site had any motors on it but the D site did, none as you portray however?

I rode a TS Jackal with an Etek a few years ago and that thing would scoot. I think that size motor is better suited to a bit larger vehicle than a bicycle perhaps? But I can think of a few applications. Thanks for sharing.

One other thing. What was your objective changing the magnets and were you pleased with the final results?

the locktite glue was a bust. i ended up mixing my own resin and it worked.
motor works way past 60v without coming apart.
