What's going on with the seat post in that last picture, where the bike is completely folded? Where did all the length go? It looks like it's about 1/3 the original length. 188.8.131.52 06:49, 12 June 2007 (UTC)
You release a clamp near the bottom of the seat post and push it down until it protrudes from the bottom. It's the seat post that holds the folded package together. See the folding guide for a clearer explanation. PhilipPaeps 18:53, 12 June 2007 (UTC)
I know the frames and other fundamentals are all the same, but shouldn't there still be a summary list of which peripheral parts are used in M3, T5, whatever? Jim.henderson 07:53, 8 August 2007 (UTC)

- Well... yes/no/maybe:
- Until about 5 years ago, the Raleigh Record tyre was the only suitable 16" tyre available and thus Brompton supplied these on all of their bicycles.
- Raleigh were the largest bicycle manufacturer in the United Kingdom, something Brompton Bicycle Ltd now is/
- Sturmey Archer and Raleigh were quite inter-linked, and Brompton were originally dependent upon SA for hubs. After the collapse of SA, Brompton hired SA's former chief designer.
- Based on the above, Raleigh should probably be noted. —Sladen (talk) 22:48, 18 March 2009 (UTC)
- Well... yes/no/maybe:
This is wrong, "Until 2007, all Brompton bicycles had "M"-style handle bars". I bought my second of three Bromptons, an S6L, in July 2006. I'm pretty sure the S bars had been out since early 2005 when the wheelbase was increased but I'd need to check the Brompton bike book and I don't get that till father's day.
an extended talk by Andrew Ritchey
Here podcast containing is an extended talk by Andrew Ritchey about the designing and especially all the hard work getting the bromptons on the market. It would seem to be a valuable source of references, and potential information for the article. I was thinking of adding to the article based on it myself, but this article isn't high enough on my priorities, nor do I have much time for wikipedia at the moment. I hope someone else can do something with it.--Keithonearth (talk) 21:35, 18 March 2009 (UTC)

349 mm wheels
349mm is the diameter of the rim where the tyre sits. This is the crucial dimension in terms of fitting tyres. So with the width of the tyre added on (at both sides) you get a total diameter of around 16", depending how fat the tyre is. See http://sheldonbrown.com/tyre-sizing.html for all the detail you could possibly want, including the fact that there are four other tyre sizes also called 16" (and all smaller than the 349mm size). —Preceding unsigned comment added by 184.108.40.206 (talk) 19:59, 13 August 2009 (UTC)
- Oh! Thanks; I applied my steel ruler to my new Kevlar (replacing one whose sidewall I tore by riding when flat) and yes, it seems about 16 inches from tread to tread. I'm trying to think where this information belongs. Certainly not in the intro to this article; maybe further down. And Bicycle wheel#Sizes says too much about law, regulation and elite hardware; not enough about customary and plebeian commercial practice. The topic perhaps needs its own article handling both elementary/commonplace questions and esoteric ones. Anyway thank you for clearing up this little point.

- Oh, my aspirations are not as high as the creation of nomenclatorial peace and concord among all pedalpushing Wikipedians, manufacturers, and national standardization authorities. Herding cats is easier. However, most articles that mention a particular wheel or tire (right way to spell it) size should say whether it's a rim or tread measurement, and the majority ought to mention both numbers as well as some sort of width measurement. This isn't a buff book; it's an encyclopedia for readers who should be assumed ignorant of the elements. Jim.henderson (talk) 02:55, 12 September 2009 (UTC)

The "cart" picture
This is something I have never observed. Ever. I started this article, I ride a Brompton in London, home of the Brompton, and I know many Bromptonauts. I've heard of (and seen) the pannier clipped to the block when the bike's folded and used as a kind of wheelie bag, but I've never seen a Brom pushed like this. I tried it, it was rather unstable (the pannier block is close to the left side of the wheelbase in this configuration, and if the bolts holding the speed wheels are not completely straight, i.e. if the bike has ever been used, the bike will also not go in anything like a straight line) and of no obvious utility (and yes I do have speed wheels and a rack). This seems to be user:Jim.henderson pushing his bike in his own esoteric way, and I don't think it should be in the article. My own pictures of the folding stages were removed, I didn't dispute that, I think this is of much less utility in the article absent credible evidence that this is a fold used by a significant number of Bromptonauts. Either that or I take a picture of my bike folded in an even odder style, but that would be WP:POINTy. Guy (Help!) 23:13, 15 January 2010 (UTC)
- There's more than one way to unfold, carry, tow, or push a Brompton bicycle ...some people prefer some ways, some others. In the illustrated "cart" configuration, think of it more like a wheelbarrow. One must use both hands to control the rotational balance, but when not moving it is self-supporting.
- Just like one learns to balance whilst riding a bicycle, one develops mechanisms to balance the Brompton whilst folded. For instance, I tend to tow the folded bicycle behind me, it ensure it doesn't fall over, I rotate the saddle ~35 degrees off-centre first. If I'm carrying a huge pile of floppy soft fabric, I'd use it as a cart with the handle bars left out. If I'm transporting a sofa, I'd drop the saddle. One perhaps just needs a little more imagination and flexibility that other Brompton riders may have discovered, or perfected techniques that you haven't thought of. My former Dutch housemate nearly always adopted the cart configuration, but would tow rather than push (with a single hand on the Brompton-provided handlebar bracing bar). It's not really rocket-science, you just have to ensure that there's a straight line between you, the bicycle's centre of gravity, and the ground. —Sladen (talk) 00:33, 16 January 2010 (UTC)
I too usually pull with one hand, except when jockeying the Brompton a few yards along a subway car floor as I did aboard the F Train this Thursday evening in the Jamaica – 179th Street (IND Queens Boulevard Line) station after a 25 mile photo expedition across Queens, New York City. To correct a minor mistaken assumption, no, as in many Wikipictures of folders in New York, I'm behind the camera, not in front, snapping this pic of the bike being moved across a small plaza near the East River and 32nd Street. I am older, taller, paler, and handsomer. Yes, a pull picture would illustrate a more typical use. I hope to catch a good one, three months from now when the annual Fold-Up Festival is held again in the same place, and maybe I can get a better background as well. As for whether the push pic is a good illustration for the article in the absence of a good pull pic, being the photographer I'll leave that judgment to other editors.
As for how best to illustrate the folding procedure, I prefer the present diagram, but if the photo sequence were reshot with better lighting and especially with a bland, pale background instead of a bold brick wall, my preference might reverse. And the new picture of frames stacked upon arrival is pleasant and informative, even if small and slightly blurred. Jim.henderson (talk) 15:50, 16 January 2010 (UTC)
Seems to me, this article says more about that company and its product than the Neobike article does. May I suggest that, under WP:SUMMARY, the coverage here should be cut to a quarter or perhaps even a tenth its present size? Jim.henderson (talk) 03:22, 21 July 2010 (UTC)
