It seems you have a bias against Riese-Muller and anything labelled "German-made". I know my bike was made to order, whether in Germany or Outer Mongolia is scant relevance if the engineering was done by Herrs Riese und Muller. That every owner of an R-M electric bike raves about the build-quality is a testament to the work-ethic and quality control of whatever factory is producing these bikes -- something most other bike manufacturers are not obviously enforcing.
I don't know (or care) what bike your pedalling, but I'm sure a side-by-side comparison with an R-M and yours would be enlightening.
And BTW, R-M owners aren't concerned about saving a grand or two if the bike they receive is everything they've always wanted.
