Dom Harvey had a 48 volt 408 in his BB drive, built about 4 years or so ago now. I think he also used one of the dual wound two speed versions an a later incarnation. http://www.evalbum.com/769 a pic of an early version.

I'm watching your build closely to see how this Cute little guy works out Malcom. I currently have a similar MY1018 set up that needs an upgrade. More power for the steep Seattle hills would be nice. Rather than try to align the sprocket by moving the motor around I think I'll probably set up a...
Dequinox, I just took five nuts about 2 sizes bigger than the bolts that go through the freewheel so they would not thread on, just spacers basically. Put them between the face of the freewheel and the back of the drive ring. Still caught enough shoulder on the freewheel to center the ring but...
I've run BB drive and hub motors. The hub motors, especially the geared ones are pretty hard to beat for all around performance and reliability. My BB set ups all needed fairly constant tinkering but when they worked were excellent. The direct drive to the rear wheel with broached freewheel...
