The motor doesn't have a whole lot to do with range - that's almost ALL about the batteries (ok - weight too!)

I have been real happy with my Briggs ETEK motor. They don't make them anymore, but there are a couple other similar motors out, like the PERM, and now there is a new ETEK-R and ETEK-RT.

BIG deep cycle batteries can get you pretty decent range, but not likely as high speed. Plenty of small lithiums would be expensive, but save lots of weight, and give you good speed.

Another advantage of a permanent magnet motor is that you CAN do regen braking with it. Of course you do need a controller that supports it. The Kelly's and couple other controllers can do regen. (However, the only person I know with direct experience with Kelly controllers had NOTHING but problems with them.)

I really think that motorcycles make GREAT EVs, but range is an issue, as your really are limited in battery space.
