>>1325831All you have to do Anon is take and swap that with a SRAM Dual Drive Hub with disc brake flange.....
This gives you a 24 speed combo, with an 8 spd cassette and a 3 spd internal hub which can change gears with a load standing still or on the go.
A must have when pulling a beast with a load
It mounts in a standard set of 135mm dropouts and can fit that same space to the same degree of precision that you have shown on your Worksman
To convert it to act like a mid drive and torque converter you have to add the second sprocket to the left side of the hub. This is the only part that has to be "modded"
Take any sprocket, and drill out 6 matching holes that will mount to the disc brake mount holes on the hub flange and simply bolt on the ring of your choice.
The freewheel on the axle is then shifted over to the left side of the hub as well to line up....there is already a slot in the axle so you dont need to do anything except loosen the set screw and slide it over.
Promise that this will work better than anything on the market
I design work bikes for a living.
PS ...... if you cant find a sprocket to add, get the dimensions of the diameter and then have a shop make you one on a CNC Plasma Cutter or Waterjet Cutter to a precision that works to your liking and fits on the disc brake mounts on the hub flange
Total cost
Used and refurbished - 150.00
New - 350.00
Will not need the front electric motor hub then either....the SRAM Dual Drive is the only affordable model that is durable enough to take the loads and shred the hills to pieces.
Also the Derailleur has to be mounted so you may loose the tensioner screws on the dropouts? It will have to be turned forward under the frame as it will need ground clearance.
