Hi Geoff and
to the forum,
The axle
and the right hand side covers are different on the front and rear Magic Pies and would both need to be changed to enable the conventional threaded freewheel to fit:
The main cast section of the wheel would also need to be reversed in relation to the stator and axle assembly so that the offset rim would be more central within the rear dropouts.
Check out
this post for further information regarding the offset of the rim.
