This channel is an absolute gold mine! I wish the Brompton website was this informative.

[@brandtdetering8486]

These are impressively well-thought-out graphics.

[@clee6746]

You video provides the most comprehensive information on helping the buyers to choose the right Brompton. I particularly like the graphical illustration on showing the rider's riding position using the rider's height vs the 3 choices of handlebars. Great video !

[@Risayogi]

I’m 178 cm (5’10”). A few days ago, I tried different options of Brompton handlebar height on my local Brompton store. At first, I want a H-type handlebar because I want a very relaxed riding position, to contrast my road bike. But, the high handlebar position made my body more laidback and causing my arms too strech to reach the handlebar, nowhere near the dutch-style bicycle with its sweep back handlebar. So I finally prefer the M-type with mid-upright position because my arms can still be in relaxed position (slightly bend).

[@northerner8018]

Excellent explanation and graphics in easy to understand format. Thank you. Should be an official video on the Brompton site as they have nothing close that compares!

[@2Bikes4Adventure]

Glad it was helpful!

[@DMulabiTalejan]

Very, very useful information and good graphics. No body had bothered to explain all this H/M/S types mumble jumble. Thanks

You are a credit to your parents. Wonderful!

[@whazzat8015]

I went full Brompton nerd on my first one. This vids info took me hours to compile on my own. Totally great presentation data and demonstration.

[@Duck_Ellington]

This has been so so useful, particularly for figuring out which handlebars to get for an extended seat post. Appreciate this video! 🙏

[@SomeYouTubeGuy]

S type bars could lead to wrist discomfort, but you don't counterbalance that with H type bars put more weight on the saddle leading to possible discomfort there. Leaning somewhat forward helps with weight distribution and better bike balance.

[@Steve-tu8eb]

Great work you put in!

[@tommyrq180]

Just discovered your channel and find it outstanding! Long-time Brompton rider. The design of the Brompton is a marvel. However, a persistent issue affecting every ride is how to find the correct seat height AND direction when unfolding the bike for a ride. There’s no good way to do this right. I put a distinct mark on the top front of my seat tube with a permanent marker. I then scratch (ouch) or scribe a mark around the seat post at the proper height and a vertical scratch mark to help me get the seat perfectly forward-aligned. Scribing the marks isn’t easy or convenient and there’s no way to use a marker since moving the seat up and down will obscure the mark. I always check for seat rotational alignment before I ride. It’s a tough problem but one the rider must confront on every ride. That’s my solution and it’s not as slick as I’d like but it works. 😊 [I have a S6L Black Edition in Lagoon Blue with all manner of mods and upgrades.]

[@2Bikes4Adventure]

Why Brompton doesn’t have engraved marking on the seat post (as found on Birdy) remains a mystery.

[@Crotoua]

So useful information👍🏻👍🏻

[@AjayAhlawat]

This is so useful! ❤

[@adrianlw2750]

Excellent vid with clear explanation. I can vouch for the standard M-bar, with top position of Pentaclip, being a perfect fit for my 33” inside leg and 5’11.5” height, with very good wrist and saddle comfort. There is a degree of handlebar “flex” with the M bar, but I have accommodated to this and if anything I find it adds to the shock-absorbing comfort for the wrist and arms. An aggressive rider may not like the M-bar flex, particularly if in high gear or on steep hills but I have found that for ordinary, all-round utility and leisure riding it is fine.

[@NoZenith]

Thanks!

[@rohbaert4062]

@Sacha Barbie The 33" are 83,8cm and the height of 5’11.5” is 181,6cm

[@GlobalAdventurer]

I agree with you, except I had to change out the stock brompton seat for a brooks saddle. The stock version was causing TOO MUCH pain in my.....😁

[@adrianlw2750]

@@GlobalAdventurer - I have a Brooks B17 Standard on mine, always brilliantly comfortable, short or long rides, and these saddles have a character that fits well with the Brompton 🙂

[@RobWhittlestone]

Excellent, well-researched video, finally providing clarity about the rather cryptic fitting information provided by Brompton (to my knowledge). I have long admired Bromptons but alas may probably not take the plunge as a pensioner.

[@2Bikes4Adventure]

As pensioners ourselves, we can confirm Brompton bikes are age agnostic.

[@GlobalAdventurer]

I'm short and got the M handle bars on my brompton. I tried the H handlebar and it felt like I was raising my arms up and I thought it would make me tired riding like that for extended periods of time. So far the M handle bar is working fine.

[@taniacruz5080]

How short? I’m 4’11 and figure the S bar is the only option for me.

[@ImranShaikh-gh2wd]

these videos are great

[@rajajesson]

These are pro grade videos 👍🏼👍🏼👍🏼

[@jazzfan7491]

Great explanation of what flipping the pentaclip can do. I am 6-1 and I think close to the top of the extended seatpost. I might need to do the pentaclip switcheroo when my Brompton arrives in 2 weeks. Thanks much!

[@2Bikes4Adventure]

Sometimes, this added 2cm makes the difference

[@johnmedina319]

Thank you

[@WilfredFumbly]

I ride an M, but wish it was an H. Why? My bike helmet has a sun visor (yay!). But on the M, that visor is angled just low enough to obstruct the horizon. I like to see where I'm ultimately headed for... and not just stare downward at the pavement right in front of me.

[@jonathanleach3914]

Very helpful.. I changed my 2 Bromptons to Joseph Kuosac bars, not for height but for width. I found the standard handlebars too narrow whereas the JK ones, even with 1 cm off, are in line with shoulders. Much more comfortable on longer journeys. Thanks for all your films.

[@2Bikes4Adventure]

So, I assume no need to change cabling and it doesn’t compromise the fold (ie., handlebar touching the ground when folded)?

[@jonathanleach3914]

2Bikes4Adventure yes. Needed an extra 2 cm or so. My bars are 158 cm across, normal are 152 cm. JK uncut are 160 but my memory is that they have 1cm cut gradations on them, so v easy with a hacksaw. I have put them on my S6R and my Alfine H11R. Thanks for your films - they are very good. Take care.

[@jonathanleach3914]

Forgot- both fold fine.

[@finncarlbomholtsrensen1188]

Scandinavian Bromptons are sold with the 600 mm saddle post as standard, so I have problems when using my B&W travelbox, as I have to remove the saddle and post. So I also have bought a telescope post!

[@bengt_axle]

I second the many positive comments about bike fit and selecting the right handlebar. Note that in addition to your body size, the lower, more aggressive position will require a greater saddle setback. With the saddle further back, your upper body weight can be offset by the hips being further back. You should be able to ride with your hands just floating on the bars, which is the setup used on a road bike. So if you have too much pressure on your hands, consider raising the bar, or sliding the saddle back (or both). On a folding bike, you might be limited in saddle setback because the seatpost is straight.

[@2Bikes4Adventure]

Excellent point. Since there is no stem between the handlebars and the steerer tube, reach adjustment can only be done by "fine tuning" the saddle setback for any given handlebar configuration. Maybe something to cover in more details in a future video.

[@e14ph]

I might buy a butterfly handlebar of even H-type for more comfortable riding, my arms are even getting sore from M-type because of lower handlebar height than the saddle.

[@umarmars47]

Terima kasih

[@2Bikes4Adventure]

Kembali kasih!

[@grahammcdonald]

I love my h-type. I'm 5'9" and it's as upright as I can get for comfort.

[@enricoflor3601]

Sad that they removed the P from the Brompton range. I find the multiposition offering very useful.

[@enriquedelgadoitt]

Hello!! I am having some issues with the slipping of the pole in my seat. Is there some tip that you recommend, i have cleaned it and tweak the nut. I read something about scratching a bit the pole? - I love your vids, they inspired me to buy my Brompton!! - greetings from Mexico.

[@2Bikes4Adventure]

Hi Enrique, We do suffer from this problem as well (as most do, we suspect!). We used disk brake cleaner on the post and inside the seat post sleeve. Kind of help, a little. Ultimately, the sleeve may need to be replace (unfortunately, this cannot be done easily as a DIY project). The sandpaper trick could work (and should not be visible if there is only one rider, as it will alway be inside the frame)). Could make the post more susceptible to corrosion however. Good Luck.

[@johnnymac8680]

I'm 5' 8" with an inside leg of a mere 29". I prefer a more upright position but I think that the 'M' type would be better for me rather than the 'H'.

[@2Bikes4Adventure]

M-Type and regular seat post should be fine.

[@finncarlbomholtsrensen1188]

I have both a carbon Sport and H handlebar for testing which will suit me the best, on my Lightweight.

[@2Bikes4Adventure]

Any problem with cable length? Do you need to move the saddle offset as well when swapping handlebars?

[@mt-tk5hp]

Great video! Btw, are you still using spongywonder bike seat?

[@2Bikes4Adventure]

Yes, Pam is still using her SpongyWonder seat :-)

Pam adjusts the tilt slightly (down) on longer trips.

[@mt-tk5hp]

@@2Bikes4Adventure I just tried it tilted on max. And Im not sure if it's just the fabric of my leggings but I slightly slide forward that i think somehow adds pressure to my thighs. Though a really big relief on the butt and sensitive part.

[@2Bikes4Adventure]

You may want to experiment to find the optimum angle.

[@frankhooper7871]

Now if only Brompton would re-introduce the bike-builder so we could actually choose the seat-post that works best for us, rather than only providing models with the extended post!

[@pimoussemars3717]

hi, nice video! why you didn't spoke about the P bar?

Because it has been discontinued by Brompton

thank you for the detailed video! i'm 5'3''. do you recommend the M or H for the upright position. i have a dutch style bike now and like sitting upright.

[@2Bikes4Adventure]

Using your existing dutch bike, measure the vertical distance between the top of the seat and the middle of the handlebar. Using this measurement and your inseam, use the graphic in the video to determine your recommended Brompton handlebar setup.

[@martindobisky8000]

Hi. Greetings from Argentina. How do you compare in terms of confort an effort the Bromton witj a 20 inch foldable bike such as Tern or Dahon?

[@2Bikes4Adventure]

Hi Martin. The last Dahons we owned/rode were Dahon TR equipped with Schwalbe Big Apple tires. The pressure in those tires was less than half the pressure in our Bromptons’ Schwalbe Marathon tires. Coupled with larger diameter wheels (20” vs 16”), it made the TRs noticeably more comfortable than the Bromptons. Nonetheless, we eventually sold the TRs and kept the Bromptons as their small form factor and slightly lighter weight made them more appropriate for the type of light touring we had in mind (even if it meant a little less comfort).

I'm a 5'5" female with average body proportions except that I'm quite thin. (105 lb.) I like a more upright position. Should I go for the M or the H? Will M be fine?

[@2Bikes4Adventure]

We would suggest M handlebar

[@gohsam79]

is the stem angle the same for S & M type? Trying to determine S or M bar for my family with riders' height ranging from 142 - 164cm.

[@2Bikes4Adventure]

The stem are not identical between S and M. In addition to the different handlebar shape, the S stem has a slightly more forward angle compared to the M-type.

@@2Bikes4Adventure Thanks! This is what i thought so too, I asked BJ London and they replied " the M stem is shorter than the S, but the angulation is pretty the same."

Can I ask. If the S and M stem height is the same? Seems to be conflicting views that the S has a longer stem and low handlebars and the M has a shorter stem and higher handlebars. Some say it’s the same. Can shed some light? Thanks

They are not the same. The S stem (as counterintuitive as it may sound) is slightly longer than the M stem.
