That was a known before the campaign ended and still roughly 1000 people supported the bike on kickstarter plus an unknown number did preorders. So I'd assume you issue is not much of an issue for them. If it is an issue for you the Helix just is not your bike - pretty easy...

Maybe you should look outside the Schwalbe brand... There is i.e. the Strozzapreti. Nevertheless the Brompton was designed as a city- and commuter bike. Which means your demand is a bit outside the mainstream. If the Brompton does not fulfil you needs it is not your bike. Pretty simple.

Just because you don't see an advantage does not mean there is none. i do see some, as outlined before.
