That's not exactly the default use of a bakfiets though is it. Roller brakes are like hub gears, adequate and low-maintenance, and very common in countries with a big cycling modal share. I'm not saying they're for everyone, but the UK market aversion to them and IGH is not necessarily justified IMO.
Lolo-
I think IGH are great

combined weight of 2 children, adult and bike that weighs 30kg or so (+ luggage, locks etc?).. are 2x roller brakes made to handle this sort of use comfortably? If there just so happens to be any hills in the area of use. In flat areas and no e assist - sure why not.
I don’t consider disc brakes high maintenance.
Maybe I’ve just been put off by all the UK naysayers : D

They’re alright, but I think a small part of the resurgence of cargo bikes is due to the consistently powerful offerings of modern hydraulic discs. I wouldn’t want roller brakes on an all in 100~200kg bike bombing down a hill at 35mph.
