If you plan on rolling it much, I highly recommend the X-Roller mod - when folded, the weight of the front end hanging off to the side of the rack/wheels makes it prone to tip over, esp. with a heavy bag clipped to the front block. I refer to it as "baby stroller" mode - I've done many miles strolling the bike (and carrying camping gear) through museums, malls, zoos, and pedestrian-only parks. I sometimes need to preempt the authority figures with "you allow baby strollers here, right?" That usually works as they realize I am no different.

I'd personally buy a new steel bike built the way you want and not worry too much about weight. My recent model M6R has an extra ~7 lbs loaded in it (~34 total), which makes it my heaviest bike, yet it is by far the easiest bike for me to carry distance. The key is the Brompton's compactness and locking fold which allows (for me) shoulder top carry, or how most folks prefer to carry heavy lumps like 5 gal water cooler jugs and sand bags. When touring, I like hiking deeply into the woods for private/secluded wild camping and often carry between 100yrds and a quarter mile, and I've hiked my whole rig up a 30 story staircase once (behind neck/two-shoulder carry for longer portages). For carrying >10yards, through doorways, up stairs, or narrow hallways, the bike always goes up on my shoulder(s).

I disagree that weight isn't important. An unfolded Brompton is compact enough that the OP may find himself just hopping off and lugging it upstairs by grabbing the middle of the frame, then folding once inside the apartment. I've done this lots with steel Brommies and if I could drop even 2 pounds off the package it would have been noticeably more pleasant.

If I ever buy another one - not needed at the moment - I'm going Full Weight Weenie Brompton with ti extremities and 2 speeds.

Got an M2R-X

As I've been debating and negotiating on the kew green M2R-X, I realized there was another Ti Brompton on Marketplaats - a red S2L-X. After a quick bit of negotiating, I bought it today. The seller had reason to come into Amsterdam (he lives about an hour out), so he met me at work and I rode it home. It's almost exactly what I would have bought if I could get whatever I wanted new. Red is one of my 3 favorite colors on these little guys. For the shopping cart routine, I might X-Roller mod described by @reppans, but I'll wait to see how necessary that feels. He's going to give me a deal on a front luggage block and the folding Brompton carrier, and I should be set to go.

It was made Nov 2009, but has the current cranks with 50t big ring, current roller wheels, freshly lubed, Deore levers, and aftermarket grips (will likely try the Ergon GP3s in a while, but these will do for now). The saddle is surprisingly comfy, at least for commuting. The suspension block is probably original (it has some cracking) and I'm pretty sure it's the soft one, so at some point I'll swap that for a firm block. And maybe get some Kojaks, and some proper touch-up paint.

I definitely like how light it is lugging it ups the stairs. Very happy about that aspect. Photos are from the ad. I took new ones, but they're too high res, and I'm too lazy to mess with them.

Yea 2 speed is lighter than the 3/6, and you have to go to Maastricht, to find much of a hill ..

My backside liked the lighter Brompton-Fizik Vitesse,* like on your green option, , than the current handle grip, under the nose B saddle.

*so I got 4 on close-out.

Congratulations on your new bike! Glad to hear you found the bike you wanted. Ride it around for a while then decide on the accessories you need or want.

And then their were two

I saw the kew green Brommie in person today. As noted, it's an M2R-X, and the forum experts dating was pretty much right on (Aug. 2008). I took it on a long test ride and it's in great shape, and rode very well. After a bit of last minute bargaining, it was mine. Or rather, it's ours, as this one is going to be my wife's. I really like the green (she loves that color), and I didn't mind the 44t chain ring as much as I thought I would. I spun out on smooth roads with no wind, but on the usual Amsterdam bike paths (bricks, virtual cobbles, lots of unevenness, along with little rises over the canals and frequent bursts of wind), the easier gearing was fine. I think the wife will want to keep it this way.

It needs a good cleaning, a new chain and rear cogs, and a front luggage carrier mount, and it'll be ready for her. Oh, and it's annoying not having the rear frame clip, so that will be added. I'm going to put the bar ends from the S2L-X on her M bars, and put Ergons for the mine. I'll also swap the saddles, since I know she'll prefer the more padded Brompton saddle with the handle under the nose. And I need new cogs for the S2L-X, since it has a new chain and the chain occasionally slips. That one could probably use a new set of cables, too, since I think it was used more extensively and the outsides of the cables look worn in places.

Does anyone know what the size of the seat post O-rings are offhand? The green B doesn't have any, and so you have to be careful not to push the post all the way down. I can order some when I order the cogs, but I figured they might be something I could find at a local hardware store.

Given the Top of the seat post tube is the planet wide normal 7/8" - 22.2mm .. that would be a good number to start with..

Thanks. The good thing is I can just fold the bike into shopping cart configuration and take it right in to get a good idea of what might work.

That's strange. A 2008 model built in August should have the frame clip fitted per factory standard. What is the frame number (behind the bottom bracket) and what the serial number (on the silver sticker on the back of the seat tube)? Maybe the bike was bought in August 2008 but produced earlier or someone removed the clip for whatever reason?

I'd recommend to try before you buy, especially as it is not totally cheap. I did not like that extendable rollers on the L-version with Kojaks as the bike tended to fall over sideways in folded state if they were not extended. Shopping cart mode went no doubt smoother in terms of rolling but the bike not staying stable with or w/o bag was not very convincing, so I removed the extender again.

Serial number (sticker):0808096652
Frame number: 264829 BS6102 (latter number more faint, but I think that's right)

I appreciate the first hand experience. As you say, they're aren't cheap, and so if they're not an excellent solution, then I'll muddle through, or get a rack if it's annoying as is.

Frame number fits to the date of the serial. So I assume that someone removed the clip. Or they forgot to mount it in the factory.

It is possibly a matter of personal taste. When I tested the Bikefun axle a while ago I did a writeup on the German Brompton-Forum. Obviously it is in German but at least you can spot at some pictures: Bikefun Teleskoprollen - Erfahrungsbericht

I just checked what my criticism was in detail back then:

- bike falls over to the right in folded state if the axle is not extended. With or w/o bag on the carrier block does not matter.
- bike falls over in trolley mode with a bag on the carrier block (no matter if the bag is full or empty) even if the axle is extended. So you cannot leave the the bike alone in the supermarket but have to hold it or to lean it on somwhere all the time.

What works better is rolling (with the axle extended). What works ok (but no better than before) ist standing w/o bag with the extended axle or standing in folded state w/o bag with the axle extended.

I quickly found this very annoying and got rid of the thing again. One enhancement but at least tree things that are worse and annoying on a daily basis was just not worth it. Disclaimer: It may be the case that it would work better with tires other than the Kojak (as the Kojak is slightly smaller than other Brompton tires) - did not try that. Possilby it may work if you exchange the small wheel on the rear blade with a bigger double wheel (available from Asian tuners). For me not worth the hassle.

Please note that my recommendation for the X-roller is for when it's paired with the 'R' rack versions. I personally do not considered the L version to be viable for 'shopping cart' mode - for one due to the dinky fender wheel and related roll-over problems, and the other due to the plain physics that the whole front-end & luggage block CoG falls well outside the triangle of contact points... wheel extension mod or not.

Even with the rack and X-roller mod, it's still effectively only a tripod as the left rear rack wheel gets levered up in the air by the counter weight of the front-end and luggage. Except in this case, the triangle of contact points has shifted ~3" over on the right side so that the CoG of the folded front-end and luggage now fall on or within it.

In any case, the OP now has both versions and can easily test shopping cart stability between the two - just strap a 10-20lbs weight on top of the front fender by the luggage block braze-on if you don't yet have the block or luggage.

I personally call it "baby stroller" mode as I found that's the best way to get a pass from the gate authorities... "you allow baby strollers here, right?"

Ah so you got the Ti S that you wanted. Also your wife also got a Ti bike. In colors that you both love. Everything turns out great in the end.

You're absolutely right, of course. I got a front luggage block along with a used, older style basket bag (pre-2016). I first tried it on the S2Rx in shopping cart mode. No good. The S bar is a little too low (awkward to push around) and, as you point out, the balance is poor. I can imagine it would be very difficult to control with any kind of load in the bag.

It works much better on the M2Rx, and I made my first successful grocery run. I like that this bag is simple and light, though I'm going to get some velcro straps and attach them so it can be closed like the current version of the bag. It's really annoying to have it half full and feel/see things flopping around when your cornering.

I also hated riding very far with the bag in front, operating like a sail. This is fine for runs to the market, but for carrying things on longer rides I think I'd rather have a medium-large saddle bag, like some I've seen in photos here on the forum. Fortunately I don't need to carry anything at all for my daily commutes, so just having a luggage block on my wife's bike will probably be all we require (though the Mini-O bags are pretty sexy).

I can see that being the case. It feels precarious riding with one hand on the handlebar, esp. with the S bar (like when I'm checking my Garmin watch). As long as the load in the bag isn't flopping around, I can see how it would be more stable.

Some load on the front makes the Brompton-ride indeed more calm. Other than that you could measure the width of your S-type handlebar. Some time in 2009 the S-bars got a bit wider (about 54cm vs. about 47,5cm before) - the effect is dramatic. With the slimmer bars the S is quite nervous, with the wider ones it rides like any other Brompton.
