He took the electric motor off and mounted a 5:1 pocket bike tranny in its place. Not sure if there was ever a build thread created. He might have placed the info in someone elses thread. Not able to find though.

Excellent Thanks...


This is what he did: "Yes the wheel had a lefthand freewheel sprocket on it. The complete bicycle was an electric model I bought on Craigs list for $50. It is called a cartridge motor, not a hub motor in the spokes.

Removed the electric motor, drilled 5 holes in the electric motor mount and bolted the 5:1 box on with a 12 tooth 1/2" pitch on the gear box for bmx chain (or ht chain).

Then had a machinist enlarge the center hole of a 48 tooth ht sprocket to fit fit the freewheel sprocket hub snugly. The sprockets ligned up easily and runs like a charm"

Was wondering if instead of going to a machinist, would this work mounting to the left hand freewheel on the electric bike?
