MY1016z3 24V 350w motor $52
24-44V controller- $13
13T sprocket - $6
18T disc brake cog - $13
#410 chain - $7
Throttle - $12 ?
Rear disc brake wheel -
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?
