take it apart, remove the reaction arm, that connects it to the frame ,
No personal experience having done this, to that product.
Internals gear hubs incorporate a freewheel mechanism in them,
then to change the gearing range, all you swap is 1 sprocket,
typically held in place with a snap ring.
Most 3 speed hubs have the spline in common, by now,
3 tabs in sprocket, following standard set by Sturmey Archer 100 years ago.
