T-Line is 7.5kgs compared to a standard Brompton at 12kgs so thats in the frame, stem & forks. G-Line is 15kgs so must have quite a beefed up frame. I guess when the Ti G-Line inevitably comes out with Carbon forks it will be nearer to 11kgs which is better but I bet it will be closer to £6k. Bonkers.
The g line will have loads of little weight penalties. Rims, tyres, brakes to name but a few.
The grading range is huge on the Alfine (just over 300%). Plus it looks like its quite high gearing. The guess is that it will start at 34 inches. But as they haven’t publicised the sprocket size nobody knows

Ask nicely and I’ll go and count them. Brompton Junction Covent Garden is 300m from my new office. I might take a test ride too. I won’t be buying one though.
When I rode my Rhino, I liked the Alfine. So much that the Genesis IO I replaced it with had the same hub. But then I discovered single speed and never went back. The biggest issue for off road was the limited range of decent 406 tyres. That now seems better. Brompton basically reinvented 16” tyres. The old 16” was not the same ERTO (305 vs. 349) and decent tyres for that size are still very limited. My Tactiv has that size
One point you won’t see is that the powder coating is mentioned as robust. The Junction test C-range have the same, and it wears off at the fold clamp pretty easily. Expect the same
I don’t commute so I don’t need a Brompton
I already have a gravel bike so I don’t need a Brompton gravel
I already have too many bikes and have absolutely no good reason to want or need one of these
I really, really want one and bike to work is about to become available to me again…..
Not sure I get the strength argument
Well look at a Brompton compared to the Bike Friday. The frame in particular.
Trusses are lighter than equivalent (strength and stiffness) beams.
I'm not hating on the Brompton, just pointing out why it necessitates being heavier.

Took one for a spin. Gearing on the demos is 52x20 and I needed 6(/8) on the flat. It’s heavy but rides well. You won’t be happy carrying it up stairs.
took one for a whizz around London today - ride is very non Brompton.
odd that they did not design though for 2.5" wide tyres
My wife’s very happy with hers, arrived a couple of weeks ago and we’re just back from a week nr Aviemore where it coped admirably with the gravel as expected. Makes travelling with 4 bikes much easier even with a van. It’s heavyish for what it is but not ridiculous but rides great, looks cool and got a few interested parties asking about it, such a well designed thing too!

So i think this is the gearing. Based on a 44mm tyre as that was the closest. Looks like a better compromise than i expected
Just when I thought I didn't ever need another bike...
I've had a 6 speed Brompton for about 10 years, for commuting - either part ride part train, or sometimes (when the weather is nice) ride the 10 miles home in the evening (I've got some hills to get up so 6spd is welcome). It's one of those purchases where I'd ummmm'd and ahhhh'd for years before buying- then once I had one, wished I'd bought it years earlier.
That its not counted as a bike when folded makes life easier on busy trains. And for little things like getting home or to work after dropping the car off at a garage etc, it's great as it'll just go on the back seat or in the dog cage in the boot. + fits under the desk means no faffing with getting out of a bike shed or locking up etc
But I'd always wished for disc brakes. The rim brakes are rather crap when you're used to 180mm or 200mm mtb brakes, especially when some knobhaed pulls out on you from a side junction when going down a hill.
Hmmm...
