To me riding my e-bike is like building a rocket. Any additional weight is not a good thing. But I respect that others have different needs.
The expensive way is to attach a hard case like a Pelican on top of the rear rack. Or see if a 3 inch PVC pipe will fit underneath the rear rack. Put an end cap on one end and use a long removable shackle padlock on the other end.
