I lucked into F/R disc hub set $20, front for eZip upgrade, rear to build wheel for this project. 36H for 26" wheel or may build smaller wheel and fit gear reduction motor inside rear triangle.
I am willing to sacrifice brake function on rear wheel. Gear-reduction is nearly 10:1 and should provide excellent deceleration from throttle release!
No freewheel.
Sprocket to freewheel adapter available from staton-inc.com

Just waiting on delivery of 18T disc sprocket.

Looking to produce the cheapest possible eBike "kit"
Plenty of gearing and voltage choices!
15-22T+ disc sprockets - 9-13T+ motor sprockets
Perfect on a small bike for the lightweight, but qualified, youngster?
Fit a 20" 20mph eBike in the trunk, or gear for the hills?

24V 350w motor = 350w @ 24V - 308rpm
24V 350w motor = 378w @ 25.9V - 333rpm
24V 350w motor = 485w @ 33.3V - 427rpm
24V 350w motor = 525w @ 36V - 462rpm
24V 350w motor = 650w @ 44.4V - 570rpm
Beyond 37V is liable to shear oem sprocket "key" ... ? (Moderate preliminary throttle or controller with reduced amps recommended.)
