I hope it's a Rohloff and not some misspelled knockoff
Seriously though, it'll fit many folders. Subject, of course, to the usual provisos about having the right version to fit the frame- if it's different from the one on your other bike you'd need a new hub to the right spec. Kinetics for one do a Brommie with the Speedhub, Birdy do a Rohloff model, Dahons have been fitted with them (not as standard, by buyers)....Plenty of people tour on Brommies, there's the Dahon Speed TR (discontinued but frequently on
eBay), other Dahon (and Tern) models will take racks....
