Hi Lutz,
yes, this figure can be backed up.
Just, funny thing - definitely not via the German manual!!
https://www.strida.de/fileadmin/user_upload/Downloads/bedienerhandbuch_Faltrad_Strida_DE.pdfThere it says you have to refer to page 63 - and this page does not exist!!
Hej MSA - Euer deutsches Handbuch ist ein Sauhaufen!!!You have to look at the English manual, page 3 - 100 kg max. rider weight are correct.

Anyway you should try Strida before buying.
If you want to carry additional tons of load then you should definitely take a look at this brand:

Kind regards,
