So amazing seeing all the in-house testing. Now I know why Seth from Berm Peak has a still functional Brompton after all the abuse he has put it through 😅
My goodness! Anyone who says a "Brompton is too expensive," should be sat down and *made* to watch this video! (Phew! I am mightily impressed that the testing equipment itself stands up to the rigors of life in the Brompton test facility.)
Your best video to date. Your confidence in front of the camera is a joy to watch. Even after seeing this video, I'm still undecided whether to take the plunge and order a G line. I think I'll sit tight until you do a thorough test ride and report. I trust your reports because you tell it like it is...warts an all.
@brilliantbikes I'd love to. But I live in a coastal town, Llantwit Major in South Wales, about 20 miles outside Cardiff. A bit of a jaunt I'm afraid. But thank you kindly for the offer.
Cracking film of the tortures Bromptons go through in the design and build processes. I’ve always known that Brompton takes great care and pride in producing the classic Brompton and it is astonishing to see what this next generation of bikes is being put through. Thank you Hannah for taking the time and trouble to show us these machines 🙂 Still wish they would give us back the 3 speed hub, if anyone at Brompton sees this!
This is so impressive! I wish every company spent as much time testing their products as Brompton. Too often it feels as if it's end users doing all the testing...
The first time I watched one of Hannah (and team) ‘s videos I thought its straight-faced include-every-step delivery was the funniest piss-take of old fashioned technical writing l’d ever seen. I was delighted. Now she’s presented an example of the kind of thing we were begging to be allowed to do. Whether you know it or not, you’ve done a fabulous service to the denizens of development labs everywhere. And you’re still quite wonderfully hilarious. 💐
Absolutely amazing! I would only fault your cameraman on his ability to focus!!!! Mind you, with you as the co star here, I too would have difficulty as well… Your commentary was spot on and banter as well. Been following your channel for a while now since owning 2 Bromptons ) A 6 speed Black edition & and most recently, a 4 speed P Line. Both black. ) I absolutely understand now why they are cost effective and how the pricing is justified. When people ask me how, why & what for, I will for say, watch this video. Nothing durable and tested forever never cost peanuts! Ironically, I am from West London, just down the road from Greenford and would say after (the original) Wembley stadium, the mythical Hoover factory ( now a Tesco…) the Brompton bike factory has firmly left a mark on this side of London! I am convinced Brompton have something here! Until the next video…Focus!
Thank you for hosting us, we really really enjoyed meeting everyone and having a chance to show how well tested the Bromptons are! Thank you for watching!
Such a great video. I have been waiting for the full version since I first saw the short showing you visiting the factory. I am also “blown away” by the “brilliant video” from “Brilliant Bikes” 😮
Impressive! I am blown away too. Gaining trust again in the brand after a crack in one frame (seatpost area of a classic one ). Understand now why Brompton is so confident that their products are that reliable. I suppose I need a more robust Brompton, a G-Line: I still cannot understand why it comes with an Alfine and not with the 12 gear HUB-chain combination. The Alfine is not sufficient uphill (only with a smaller chainring)
My 2011 Brompton S1L mark 4 has endured about 20000 kms. I've ridden it on tarmac, gravel, singletrack, fireroads and all in between. I've ridden it all year. No problems.
Great vid as always - learned heaps about how a Brommie has such a good reputation. Also explains (almost) why they are relatively expensive. Seems they have another double-barreled Billy in the ranks :)
Great video! It’d be great to see the computer simulation (FEA) and structural optimisation they do before a concept goes anywhere near production. There’s a huge amount of ‘secret sauce’ in the design phase, that most end users have no idea happens.
Great video! Sad to say, many Brompton users in Asia replaces many Brompton parts plainly for aesthetics. Many do not understand that all of these components are tested according to the bike's design and intended purpose.
Hallo Hannah, vielen Dank für den Film. Ich fahre brompton seit 15 Jahren. Ich liebe meine brompton Fahrräder =Freunde. Das g line fährt sich im schweren Gelände fast wie ein Rotwild .
Amazing video and exactly what I wanted to see so thank you for providing it. However the camera focus at points honestly could do with some work 🫣 really off putting but understand you only get the once chance to record. I do have a question! Do they have a machine that replicates the forces applied to the chain stay when climbing out of the saddle? Cause I know and expert metal worker who was surprised they used a flat bar instead of tubes on there rear triangle and mine broke in this area on the titanium rear frame. Brompton never got back to me on the cause of damaged but was covered under warranty. Any input would be great. Thanks once again
Thanks for watching! There were a few points we had to choose the voice over the picture quality, I guess that’s life! I’m sure they do test it, just not on the ridges we saw and features in the video!
Brilliant as always and I love the cut outs at the end 😂 cant wait to test ride a G-line electric although I may wait a bit buying one to ensure that the usual hick ups for new models are all resolved
Thank you, this is really interesting to see how brompton automates the different load scenarios. What I didn't see in the video was some tests that simulate left/right load. I.e. going on a curb at 45 degree etc. Do they do this as well in-house or via road testing?
I am waiting for the videos on travelling with a G line on public transport. I need to know if it is manageable on buses,trains and airplanes like a standard Brompton. Enjoyed this video and really it shows why they are of quality and expensive
Many thanks for this masterpiece !! 🙏🏻❤️ 14:40 Strongly wish they will do a full titanium G line (a GT line then?), do you have some idea about if Brompton expects to do that in the future ?!?
I also have a P line, but I was wondering how the G line compares when riding casually I believe it’s not for the city but for the country would you agree?
@@richmck007 I have yet to ride my new bike. I got injured and can not use my elbow right now. These are my thoughts on picking them each up while folded: I would want the P for when hopping on and off public transport a lot but the G when I can get away keeping it unfolded all day. Time will tell if this holds true. Greetings from Germany
this is why I am bit wary about replacing the genuine Brompton parts with aftermarket ones. For things like the triangle, seatpost and other important structural things, did the manufacturer stress the components as much as Brompton did? Very very cool video..... if there is any doubt where your (substantial amount of) money is going when you buy a Brompton, this should alleviate some concerns.
Thanks for watching - and sharing your thoughts We were blown away with the "hammering" they were giving the bikes (we had actually visited the facility about a month ago during a visit launching the G Line - but had to come back to film R&D as at that point (apparently - and we didn't pay enough attention) it contained TOP SECRET stuff) We agree abut the aftermarket parts - we have seen quite a few that don't fit / have bad tolerances etc - sometimes leading to other failures on the bike
I have 2002 6 speed Brompton,it has the Sachs 3 speed hub ,never gives any trouble .it is about ready for new hingepins and wheel rims but all original after 22 years
Thanks for watching With the exception of the disc brakes - these tests were originally developed on the C Line There were some C Line bits in the test rigs
Thanks for watching - and for the question The G Line is definitely tested in the wild - at the time we went - there were riders in Spain riding them for for 3 months all off road (we think one had clocked up 15000km) There were also C Line parts in some of the machines we saw
@@brilliantbikes I would love to see you cover the problem so many people seem to be having with the front soles rubbing with the rear 6 speed hub indicator chain when folded. As mentioned I have issue when rolling the bicycle in shopping cart mode. Specifically, when I pushed the handlebar to roll the bike, I started hearing some loud pinging sounds. After some investigation, I figured out that the noise comes from the collision between the front wheel’s spokes and the chain tensioner nut. The nut is installed outside of the rear derailleur and it helps keep the chain taut when the Brompton is in folded or unfolded position. The nut protrudes more on my bike since this is the 6-speed Brompton c line. Therefore, when I roll the bike, the front wheel makes contact with the ground and rotate as well. The tiny rolling wheels on the rear wheel obviously can’t provide enough clearance to lift the front wheel. So, when you roll the bike, there are more chances the spokes will hit the nut. I had to tilt the bike slightly to temporarily fix the issue. If the problem persisted, it would be a huge disappointment. The handlebar catch has a bulge on it that hits against a bracket on the stem which is supposed to prevent the wheel from coming too close to the gear chain. I took it into the Brompton Junction store in New York and their solution was do not roll the bike ever That’s like going to the doctor and asking why does my foot hurts when I walk and the doctor’s solution is to never walk. I think the problem is that the bulge on the catch was meant for two and three speed bicycles and not necessarily for a six speed. I have done some research and added rubber bumper on top of the bulge (essentially making the bulge larger) on the catch to make it larger so when it comes up against the bracket on the handlebar tube it keeps the spokes away from the chain. My recommendation is to update your handlebar catch with a larger bulge/protrusion or come up with some sort of additional bumper as I did.
A kiedy będą testować zasięg eBromptona przy normalnej jeździe? U mnie to 25 km, a po zmianie silnika i akumulatora na nowe w wyniku awarii - to samo...
Thanks for watching and the question Yes this is R&D / testing If any change is made in production then they will re-test incorporating that change That’s why (it used to be a complaint we heard a lot) Brompton appear to take a long time to implement changes - as before release they run test after test
I have seen a man here on UA-cam, making jumps from high up on his Brompton. A thing I most likely wouldn't even try on my expensive, full XTR carbon Mtb? But I would have liked a more more easy exchange of the hinges, as on the new G-line. But - in spite of hard testing I have also seen broken, ordinary type back-frames, both from the US and the local: "Brompton Guy", from Scotland! And I don't think they are being treated that well by Brompton, it seems - without knowing the actual circumstances! I do like my own, now much lighter than 2019 Superlight, for its fold and ability to be brought to anywhere as folded, but a G-line compromises that, for a little better ride, eventually? But I hardly think you are buying a Brompton for its ride? And it seems that Brompton forgot to test the T-line in the moisture and mud-chamber - with those large open holes in the frame, letting in water and gravel to the crank and ball-bearings in front! 🤔 Finn. Denmark
@@HenryWilkinson-c5n My SuperlightM6LX has been modified to now below 9 kilo, with mudguards, and maybe not that many loose parts on the original bike still left untouched and not changed to titanium and carbon😄! But it still looks near fully original, til you start lifting it.
@@HenryWilkinson-c5n A Brompton is fast from stops, but the small wheels gives a higher rolling resistance during rides and there is a reason why most Mtbs are now 29"! And for a long time I didn't know for what purpose I had my low gears, of 6, til I met an absurd serpentine road going up, and had to walk on top. I still find it mostly - funny to pedal hard up a hill and being able to walk faster! You are able to do on a Brompton what a "Normal Bike" does, but it is much harder to do it! But going/racing down the serpentine road, with often full stops to pass the "Cattle Bars" crossing the road, my brakes never let me down, so disc brakes aren't really needed, also for the low speeds being reached on a Brompton! Finn. Denmark
You are able to buy a 7 speed wheel and chain-gear changer from the East, which gives less weight and no internal friction from gears in the hub! I would prefer those from heavy internal gears. Finn. Denmark
@@HenryWilkinson-c5n I could invest in a Titanium Frame from China and built an even lighter bike from it, but as a weight challenged, tall person I wouldn't trust my life on riding one! They are mostly built for small Asian person sizes. Finn
...half of our bikeways run through the woods so it looks like 7:04 most of the time! The hub doesnt mind the mud, the derailler however may become unreliable!
Geared hubs aren't sealed against moisture and most people pressure wash their bikes when covered in mud, I doubt if any manufacture guarantee long life on these parts.
This is why I don't really use most of the aftermarket parts for my Brompton. Not to mention 95% of them are overpriced, like the Ti Parts or ColorPlus. I don't know why people pay high price for parts without enough safety and durability test done by 3rd party.
I've used my p line once and can tell you these advanced roller wheels are pretty crap, there's just 1 cm of wheel that's stopping your rack from bangs and dings off the floor, not enough clearance. Durability issues with these roller wheels, don't like them
Thanks for watching and taking the time to comment Compared to many of the bikes we see - they are not crappy (unless ridden through a steaming pile of dog pooh left behind by some inconsiderate dog walker ;-) )
So amazing seeing all the in-house testing. Now I know why Seth from Berm Peak has a still functional Brompton after all the abuse he has put it through 😅
We totally agree! He did abuse it! And it looked fine! Thanks for watching!
The G line is so exciting. The best thing that happened in the cycling world for a long time.
Thanks for watching! They are great to ride!!
My goodness! Anyone who says a "Brompton is too expensive," should be sat down and *made* to watch this video!
(Phew! I am mightily impressed that the testing equipment itself stands up to the rigors of life in the Brompton test facility.)
I really was so so impressed when I saw it! It’s truly amazing what Brompton do to the bikes, so we can enjoy them!
Thanks for watching (again 😀!)
Your best video to date. Your confidence in front of the camera is a joy to watch.
Even after seeing this video, I'm still undecided whether to take the plunge and order a G line. I think I'll sit tight until you do a thorough test ride and report. I trust your reports because you tell it like it is...warts an all.

I saw three young ladies this morning and they were riding bromptons , i think they call themselves the Bromptonettes .
Nice video thanks .
Funny! Thanks for watching!
Wow... so gut what they are doing. I'm proud to be part of the "family" 😊. Ich liebe mein Brompton ❤
Thank you so much for watching! It really is impressive what they put the bikes through!
This video is so well made. The combination of A roll and B roll really explains all things so well.
Thank you so much, I think you made the camera man smile! Thank you for watching!
Amazing, thank you and Brompton for showing this.
It really is so amazing! Thank you for watching!
Wow thats really impressive. I bought my little Brompton three years ago an no complaints so far. Say hi to Henry the handlebar tester :-D
Thanks for watching all the way to the end! It was fun to make!
Thanks for this brilliant video. Quality,quality,quality. Without a doubt.👍
Thanks for watching! It was really amazing to see all the testing that goes into making the Brompton so good!

Thanks Andy
We really appreciate your kind comment - especially coming from you !
This is such a good video. It's very insightful into how they developed the brommies!
It was really amazing to see, and so glad Brompton let us have an opportunity to show it! Thanks for watching!

They are more robust I think than we thing they are! Thank you for watching!
I’m impressed. Another nudge to press the pay now button😀
Thanks for watching! We were so impressed at all the rigorous testing!
Great hosting Brilliant Bikes for the morning to make this great video :)
Now you know why our bikes are so reliable.

Thanks for watching! Yes I do think they are very robust bikes!
Wah, Singapore being mentioned and tested….👍🏼👍🏼👍🏼
Thanks for watching! It looks shot and humid! Right when are we coming for a ride….??
that was very interesting but also kinda...upsetting at the same time :D Thanks for the share! :)
I know I did feel sorry for the bikes to begin with, but then realised that they must realise they are helping! Thanks for watching!
Another brilliant video, thanks! Look forward to pick mine up soon...

That is indeed, some rigorous testing.
Hoping to go on a tour myself soon...
Thanks for watching!
It’s amazing to watch these bending machines in action-no humans harmed! 😅🍌

Good JOB!

Whoa! There's no reason to worry about breaking a G line Brompton riding it harshly! Tortorous testing!
Thanks for watching! They also do the testing on the standard bikes!
I am missing a test dummy on that bike in the sludge tank. I sometimes feel like I live in that tank while cycling.
😂 thanks for watching! I totally agree it’s cycling in the UK in the winter!
😅 Now I know why my 25 year old bike rides like new.
I know it’s amazing how well they are tested! Thanks for watching!
Hannah, Re testing. May I enquire whether the wretched Tubolitos were mentioned as part of the programme ?????
Thanks for watching
There was no mention of orange inner tubes!
@@brilliantbikes Thought not !! 🙂 🙂
With all this testing my battery is knackered and chooses when it actually works
Thanks for watching! I’d take it into a Brompton dealer to have it checked over.
Would be nice to see 12 speed bikes on the wet sand test as my derailleur stops working in wet conditions in less then 50 kilometers
That’s very strange as the bike they were testing was a four speed! Can you check it’s all clean and set up correctly.
Thanks for watching
Did they say if the regular brompton c lines go through these tests as well?
Thanks for watching
With the exception of the disc brakes - these tests were originally developed on the C Line
There were some C Line bits in the test rigs
Lets hope they will build alu frames too someday.
Thanks for watching! Let’s see what the future holds!
Do they make a test like this for the c explorer too?
Yes! They use all the same test rigs and re-test them if they change anything!
Thanks for watching!
I know the C line has been tested 'in the wild' but do they also test it in this facility or is this just for new R&D?
Thanks for watching - and for the question
The G Line is definitely tested in the wild - at the time we went - there were riders in Spain riding them for for 3 months all off road (we think one had clocked up 15000km)

That’s like going to the doctor and asking why does my foot hurts when I walk and the doctor’s solution is to never walk.
I think the problem is that the bulge on the catch was meant for two and three speed bicycles and not necessarily for a six speed. I have done some research and added rubber bumper on top of the bulge (essentially making the bulge larger) on the catch to make it larger so when it comes up against the bracket on the handlebar tube it keeps the spokes away from the chain.
My recommendation is to update your handlebar catch with a larger bulge/protrusion or come up with some sort of additional bumper as I did.
We don't get 40 degrees C here in Singapore (37 highest recorded), but good to know that Brompton has factorered in future global warming 😅
😂 thanks for watching!
It was hot when I last went!
Weey, I'm first. I love your videos. Always brilliant
Thank you for being first! And thank you for watching!
A kiedy będą testować zasięg eBromptona przy normalnej jeździe? U mnie to 25 km, a po zmianie silnika i akumulatora na nowe w wyniku awarii - to samo...
Thanks for watching. They do test it, do you ride in high power, that normally makes it last a shorter range
@@brilliantbikes only two leds
I want an electric G line IN BLACK. Why only those 3 colors?
Sorry I can’t answer that! Fingers crossed for more colours in time!
Thanks for watching!
02:57 Oh look, a T-line frame with a G-line rear, hmmm I wonder when that’s due to market…
Thanks for watching! Sorry to disappoint you, but that’s the Traildust white G line main frame with an Adventure Orange rear triangle.
But what’s tests do they do for each freshly made bike? I believe this facility is for design and prototype testing?
Thanks for watching and the question
Yes this is R&D / testing
If any change is made in production then they will re-test incorporating that change
That’s why (it used to be a complaint we heard a lot) Brompton appear to take a long time to implement changes - as before release they run test after test
I have seen a man here on UA-cam, making jumps from high up on his Brompton. A thing I most likely wouldn't even try on my expensive, full XTR carbon Mtb? But I would have liked a more more easy exchange of the hinges, as on the new G-line.
But - in spite of hard testing I have also seen broken, ordinary type back-frames, both from the US and the local: "Brompton Guy", from Scotland! And I don't think they are being treated that well by Brompton, it seems - without knowing the actual circumstances!
I do like my own, now much lighter than 2019 Superlight, for its fold and ability to be brought to anywhere as folded, but a G-line compromises that, for a little better ride, eventually? But I hardly think you are buying a Brompton for its ride?
And it seems that Brompton forgot to test the T-line in the moisture and mud-chamber - with those large open holes in the frame, letting in water and gravel to the crank and ball-bearings in front! 🤔 Finn. Denmark
@@HenryWilkinson-c5n My SuperlightM6LX has been modified to now below 9 kilo, with mudguards, and maybe not that many loose parts on the original bike still left untouched and not changed to titanium and carbon😄! But it still looks near fully original, til you start lifting it.
@@HenryWilkinson-c5n A Brompton is fast from stops, but the small wheels gives a higher rolling resistance during rides and there is a reason why most Mtbs are now 29"! And for a long time I didn't know for what purpose I had my low gears, of 6, til I met an absurd serpentine road going up, and had to walk on top. I still find it mostly - funny to pedal hard up a hill and being able to walk faster!
You are able to do on a Brompton what a "Normal Bike" does, but it is much harder to do it!
But going/racing down the serpentine road, with often full stops to pass the "Cattle Bars" crossing the road, my brakes never let me down, so disc brakes aren't really needed, also for the low speeds being reached on a Brompton! Finn. Denmark
You are able to buy a 7 speed wheel and chain-gear changer from the East, which gives less weight and no internal friction from gears in the hub! I would prefer those from heavy internal gears. Finn. Denmark
@@HenryWilkinson-c5n I could invest in a Titanium Frame from China and built an even lighter bike from it, but as a weight challenged, tall person I wouldn't trust my life on riding one! They are mostly built for small Asian person sizes. Finn
Thanks for watching! I understand the T line has been tested as rigorously.
It's a lot of jargon so we let you off. Wait, it's Brompton jargon which you're familiar with......
Thanks for watching! It was a lot of information that to get across in one morning!
...half of our bikeways run through the woods so it looks like 7:04 most of the time! The hub doesnt mind the mud, the derailler however may become unreliable!
Fingers stored they can cope! They hanks for watching!
do they refurbish Bromptons? I bought mine in 2003 and have done thousands of miles on it
They do know do refurbished Bromptons 😀. Thanks for watching!
Geared hubs aren't sealed against moisture and most people pressure wash their bikes when covered in mud, I doubt if any manufacture guarantee long life on these parts.
Thanks for watching. A bike should never be pressure washed, and I’m pretty sure that doing that would void most warranties
But they forgot to test the bolts! 😏
Thanks for watching! I guess the T line bolts they learnt over time.
🙂👍
Thanks for watching!
To the testing to be valid each bicycle has to be manufactured to the exact same standard.
Thanks for watching! They are all made to the same standard and any changes to the production, they re-do the testing!
This is why I don't really use most of the aftermarket parts for my Brompton. Not to mention 95% of them are overpriced, like the Ti Parts or ColorPlus. I don't know why people pay high price for parts without enough safety and durability test done by 3rd party.
Thanks for watching! We have been so impressed by the testing they do!
How I wish the G line is slightly lighter. My full sus MTB is about 12.7 kg.....haiizz
Thanks for watching! My MTB is also lighter. Maybe in time it will go on a diet
Great video, BUT, please stop saying "so" at the start of every sentence, kind of distracting.
So sorry!
Thanks for watching and the feedback :-)
I've used my p line once and can tell you these advanced roller wheels are pretty crap, there's just 1 cm of wheel that's stopping your rack from bangs and dings off the floor, not enough clearance. Durability issues with these roller wheels, don't like them
Thanks for watching. To date we have not seen any issues with them.
Great, now lose 6kg from the g line!
Thanks for watching! Fingers crossed in time the G line has a diet, but for now it’s pretty fun to ride!
The G line is way too heavy for a bike.
They should have used Aluminium composites for the forks to get weight down.
Thanks for watching!
Testing lab? 🤣😂😂😂 What is it? A vaccine?
Thanks what impressed us so much! So very well tested! Thanks for watching!
Blows my mind that such a crappy bike even has an RnD centre....
Thanks for watching and taking the time to comment
Compared to many of the bikes we see - they are not crappy (unless ridden through a steaming pile of dog pooh left behind by some inconsiderate dog walker ;-) )
