It either comes as a basic hub that you can lace to a wheel or a full on replacement wheel that you just swap on the brompton.
It isn't clear to me whether the Pantour hub is still available. Moreover, even if you can still get your hands on one, manufacturer support appears to be sketchy at best. Every once in a while a thread among the recumbent guys/gals pops up regarding the Pantour hub with someone trying to fix/replace/do-something with their hub and unable to contact the manufacturer.
