okay, thanks for the info. I mentioned these electric kits to my young brother out of university and he would like to add a ~350 - 500watt wheel motor kit on his bike, along with an A123 pack, for about 15-20 mile range unassisted at maybe 40km/h?

It needs to be a rear hub motor, and have 8 speed cassette with disc brake mounting. I would like for it to be a 36V unit, as that would allow me to run a nice 12S A123 pack.

I have looked around for kits, some are what I'm looking for, but are front only hubs, then some are rear, but no disc brake....etc. Just trying to find the right one!

He will spend $400 for a kit NOT including batteries.
