OK, I've been reading up on motors, controllers, and batteries.
I'm looking to build up a budge electric motor kit, so the hub drive is out.
I've found the Currie (disc brake side) and TNC mounts (derailer (sp?) side) for cheaper than I can make a mount.
Freewheels and rear hubs
Disc side drive options look like:
a) Hub adapter.
b) Mount fixed sprocket using the disc mount, put freewheel on the motor.
How often are are the bolts ripped out?
c) Hub adapted specifically for a freewheel. (Currie rear hub)
Gear side options.
a) Remove the cassette and put on 2 freewheels like in this kit.

Is there a way to remove an 8-speed cassette, put in a 5 or 6 speed cassette and run 2 freewheels? Since the rear hub gear side is designed to take the stress of a drive system, this seems like the best way to go.
The more I read, the less money I see wasting on the wrong hardware.
Thank you in advance.
