Good to see that Brompton addresses the demand for a wider gear range for hills. This solution doesn‘t convince me because it misses the simplicity Brompton stands for. Usability is complicated and service costs might be high. The external components of the 6-Speed wear out quickly on my bike. From my point of view priority should be fixing quality problems with the 6-Speed first and then creating a simpler 12-Speed.

Kinetic cycles of Glasgow make an 8 or 11 or 14 speed hub gear conversion. Cheaper less fiddly, more reliable. Why do Brompton do things the complicated way?

Hahaha if you want a more versatile folder, this isn't it. This is a hacked solution that is absolutely baffling from a premium brand like Brompton, painted up to look like a feature rather than a bug. The intuition of which hand to use for main shifting is reversed. You have to stop pedaling to shift the hub. This is disastrous. A slightly larger wheel, ISO 406 or 451, would allow a long-cage derailleur with multiple large chainrings. And if that's not your bag, you could have far better, premium hubs from Shimano or Rohloff on a 16" wheel, with a wider gear range, far less complicated shifting, and no overlap in speeds. Brompton's close relationship with SunRace is hurting the customer.

I would like to find the configurator on the Brompton website to be able to make my bike tailor-made

Is the 12 speed bike folded size the same as 6 speed?

And is it the same for gear indexing?

Given all the R&D that Brompton go in for it is surprising that they have yet to contrive a quick release for the brake caliper. The four speed mech looks fine but the chain tensioner is ugly (possibly because it brings the chain so close to the dirt).

Well there's a load of admin to deal with - the 6spd is relatively straight forward in that it's really a 3spd with high and low ratios for each 3. Changing down or up on the hub is a relatively quick and simple flick of each thumb to bring the derailleur up or down one to match - such as going from theoretical 2nd to 3rd gear as it is 1st-low to 2nd-high.

What we had waited for is a good IGH hub, and that is it. 8 or 11 speed is enough (I am building a 14 speed Rohloff version, since I could not buy a good model from you...) I bought the 6 speed 3 years ago, and I threw away the derailleur after a month, it was horrible. It is a bad idea to combine an IGH where you should stop pedaling for a gear change with a derailleur where you have to pedal for a gear change. Other than that it needs more maintenance. And according to your charts it is way overgeared... (that is easy to solve fortunately). I am not impressed. Proprietary stuff all over again. Seeing where this is heading probably I would not buy a Brompton again.

Indeed, I have a Giant 16” folder with a 7 speed derailleur in the rear. It looks like the lower derailleur pulley is close to the ground, but it’s never hit anything. And I put one of those derailleur guard thingies on it as well. A regular cassette hub would have less friction than the SA 3 speed, and all the difficult maintenance that planetary hubs demand would be m obviated. The setup would be a lot lighter too, you could probably reduce the weight by up to a kilo.

Imagine needing to remember to freewheel up a slope and lose speed cos u forgot about the eventual hub damage and failure. And then imagine needing to deflate tyres just to get it out or in lmaooooooo.

6 years behind Indonesian hackers.

I have thought a long time over the how and why... The 3x4-solution looks somehow ugly to me. So why is it that way? - I presume, this are the reasons: - Brompton is somehow connected with the former brand StormeyArcher. What other reason could hinder them to put a simple solution (e.g. 8 internal gears) into the line? - Brompton has coupled together this old StormeyArcher with the system of the 4 outer gears (which already has been developed too) - Why now this 2 completely redundant gears? --> simple: This is the one and only combination possible which makes more or less sense without changing the internal hub. - Why not just throw away one (the largest) outer cog? Then there would be no redundancy. Would a 3x3 not be a cleaner solution? --> no, because then you would loose the one and only point making sense for this 'new system' - the uppermost gear for hills. So - you have all this hassle with switching gears (1 up + 2|3 down, 1 down - 2|3 up) and carrying around one additional cog - just for having one gear on the high side. For a folding bike. Which should be simple and light. Sorry to say that Bromton: I as a customer of a 6-gear C-line would have bought this ridiculous expensive T-Line with more gears (e.g.6). But at this price-point I do not want to have the feeling, invested thousands of € for a compromise which is not technically necessary. There is simply no technical reason to stick with the StormeyArcher internal hub. Why no Alfine? Or one of the Rohloff's? At least for the expensive T-Line? Or 2 front-cogs? - The simplicity of a folding bike has gone anyway with a 3x4-solution... Of course I listened what Brompton told about the principle of the 12-gear-system: Brompton: You do not switch internal gear very often. Unless it is time to switch to the higher or lower range. Most of the time you will use just the outer 4 gears. My person: Yes, if you are lucky, then this maybe right. But if you are not lucky, you will have to switch the internal gear very often. As in my case with the C-Line-6-Speed. But compared to the 6-speed where you just switch ONE gear on the left side every second time - the 12-speed solution does not have this constant way of changing gears. And when changing, you have to go 2 or 3 gears up/down on the left side and one on the right. The more or less constant and simple way of the 6-speed is no longer there. Which makes the 12-speed-system in my opinion a cumbersome and unnecessary complex solution.

Alfine 11 gives 409% or so, but wider spacing of rear axle, possibly making the fold a bit larger (112mm axle vs 135mm axle for Alfine, still acceptable, I'd say). Alfine 8 is not worth it at 307%; both about 1665-70g. Rohloff is also 135mm axle, about 1700g, but the cost is on a different level. Brompton BWR at 302% weighs 944g, costs US$180.00

@@oe59 Brompton should offer the 6-speed-variant at least for the T-Line. I have had the oportunity to try out the 12-speed-P-Line --> everything I presumed above I got confirmed... Absolutely confusing. When you need to switch the internal gears, you have to switch 2 or 3 times on the left. 2 gears are completely redundant --> you have 10 gears Far to the fast side which in average you will not need

y am puuuuurr...😞

I think it's enough for a talk of several hours, but to summarize it in two points, this is my opinion: 1 - The weight. The P Line and T Line started a new path for Brompton with respect to gears and weight. The 4 gears are a good option and open the way to a future where there are more gears and more range but with the advantage of low weight. There are already options from alternative brands of 7 gears with a wide range and because they are external gears they maintain the advantage of the low weight of the bicycle. What Brompton offers with this upgrade is to buy a T Line, spend extra money on the 12 gears... So that it ends up having the weight of the P Line. Has no sense. The ideal would be to increase the external gears while keeping the bicycle below 8 kg. 2 - Has anyone stopped to think about how complicated it will be to change between 12 gears by combining 2 shifters? Starting it would be: Gear 1 on the left, advance on the right from 1 to 4, go to gear 2 on the left, return right to gear 1, advance from 1 to 4... Not to mention that the internal gears are used without pedal, but the external ones are changed by pedaling, you have to do all that at the same time... If you are going to advance down the path of internal changes despite its weight, put an 11-gear Alfine HUB, all in a single shifter .

Why does this cost £150 more than the six speed? The Sturmey Archer 4speed hub is only £18 more than its 2 speed. Sounds like a ploy to sell overpriced, unnecessary "solutions" to the nieve

Just get a TERN VERGE X11 already. 11 speeds. Fast as a road bike. And climbs hills like they dont exist. And is the best looking folder ever made. For £2500.

I love my Brompton 6-spd overall, but the idiotic gearing is its worst feature. This 12-speed just doubles down on the insanity. It barely has more range than the 6-spd, is even more complicated, and has overlapping gears, which means shifting up or down over those overlaps is like driving an 18-spd manual tractor trailer - not exactly user-friendly. I have no idea why Brompton doesn't simply switch to a 7-spd or 11-speed hub. It would be *WAY* more user-friendly, and more reliable.

Why did they use an AI voice?

Cost cutting? Recently they been looking for content creators in Asia. They expect the person to make a video for the opportunity to work for them for free 😂. They will judge your video to deem if your have the honor to work for them for free. Time money your creativity and equipment in exchange for early access. No mention of compensation or free merch or free bikes. Nothing 😂 Why are they so cheap? Wonder what their sales are like post pandemic

This is an absolute disaster of a drivetrain, how in the world is it being marketed as the premium solution of an already premium brand? Who hacked this together? Who thought this was a better idea than just biting the bullet and contacting Shimano or Rohloff, or waiting for SunRace to develop something better? A slightly larger bike with a proper long-cage derailleur touring drivetrain is far better, and failing that, the aforementioned hubs would also be better. Brompton should take a massive "L" for this one.

look cheap..

It's about time.....

Why can't Brompton just make a normal 1x8,9, or 10 spd?

Because the derailleur must recover the slack of the chain when folded. No standard derailleur can do that. Also, on a Brompton one expects a system that is easy to maintain and long-lasting, i.e. internal gear hub.
