Custom Off-Road Brompton Will BLOW YOUR MIND: The Build!

- A classic Brompton folding bike, it serves one purpose, which is for short trips...but does it have one purpose? Can we turn our GCN Brompton into a MT-Brompton? We have no idea if it's a good idea but Alex is on a mission to find out. It's time to build!

Who would build an off road Brompton? 🤘
I am surprised they don't offer one stock. After all these years they don't offer a more heavy duty version with off-road tires. Bike Friday has done this for quite some time now.
The Brompton folds to enable multimodal transit. Who is taking a train to the trail? IMO it's just a less effective mountain bike.
You need off road wheels and tyres to cope with the roads around Bath tbf. Reminds me a bit of the Cannondale Hooligan.
What was the final weight?
My Brompton Bicep is already at its limits.
Alex, how much would the Brompton cost to begin with, and then the rebuild, if someone were crazy enough to follow your example?
Nice!! Looking forward to the review video. I am surprised you did not mention where the kit come from (Kinetics)
Totally missed the opportunity to have an impeccably dressed Si drop the Brompton off for Alex as "Q" to convert before heading out on a mission. #GCN007
It used to be the GCN Brompton.
Now it's the GMBN Brompton
Started from the bottom now we here ....
@gcntech started from the *Brompton
Excellent. I have a “normal “ Brompton with an 11 speed Alfine hub. Really good hub although adds weight. The kit from Kinetic is brilliant
An 11 speed Brompton would seem to be impossible to stop 🙌
I'm pretty sure Simon got the idea from me 🤔 However good to know he watched my video. My build was similar but went with the di2 11 speed and hydraulic discs, looking forward to see if he can tackle a mountain like I did.
It turns out GCN mega base wasn’t a joke, Alex is just describing it.
Mega base is certainly no joke! Top secret GCN HQ is where the magic happens, think yourself lucky that you've had this much clearance 👀
How many damn security doors does one need to go through?!?!?!?!?!
Right? I'm intrigued by the gcn mega base tour
And the fire escape?
How very Maxwell Smart of you.
@@nateisrightWe're just missing the fall into the phone booth at the end.
Shhhh 🤫 You saw nothing 🕵
That's Kinetics rearframe and fork from scotland!
10 out of 10 for that intro GCN team 😂
Shucks ... you're making us blush 😳
Ok. Thanks Alex and crew...The "Why are we doing this '"? guy is effing awesome , impeccable timing and diction , BAFTA nomination in the future! Good job on the Bromster. Bromzilla , Bromasaurus Rex ...etc
Great job on the editing, and give that person a raise. It should’ve been a subject I care a little about but you had me at the intro and love the hammer sequence into the music. Really out done yourself.
The power of a good edit 😉 Great to hear you enjoyed the video - enough to make you want to try an off road Brompton?
@@gcntech let’s not get carried away
This is more secure than MI-6... James would be jealous
Alex needs to join a trade union, Alex is doing all the work whilst Si is just going to have all the fun.
Those Shimano rotors only have "lightweight racing" 14mm deep brake tracks, and those TRP/Tektro calipers fit "heavy duty" 16mm deep brake pads. A common/fatal mistake I've often seen that eats very deep into 2mm of rotor spiders and causes rotor collapse. I use Magura MDR rotors with Spyre calipers.
More brompton builds please. I saw a super brompton in Singapore this year. Titanium frame with carbon everything else. Probably after market since it was 11 speed as well.
Ooooof sounds super bling! Brompton crit racing anyone? 💨
Some Singaporeans are getting custom Titanium ones from Taiwan instead of the T-Line
My mechanic went with 20" disc brakes and Shimano Ultegra
Dutch Firm: Bromptonian builds Off Road Brompton versions, triple folders and repair parts for broken frame parts! But if in need of an MTB folder, try American Montegue, a former Army bike also now in civilian versions!
Get a Bike Friday All-Packa, no mods needed, and all parts are standard not generic. AND it folds ;-)
Interesting! Does it still fold? 👀
Wow! Nice!
Nice one again Adrian.
Well done, Major Boothroyd!
niceeeee! Always wished the Bromptons came with discs
Yep, like it. Doing a (re)build such as this is what bike life is about. Have fun with it.
Bikes are made to be fun, no more so than the humble Brompton 🙌
Is Alex planning to take that jacket back to the shop? The vents are still sewn closed. Maybe it's to turn the air into turbulent rather than laminar flow.
C’mon guys, you might have at least mentioned Ben at Kinetics. You know the guy who made the kit you just fitted?
Would really like to see a video on folding bikes. I travel a lot and don't always find a place to rent a bike. I am intrigued by some of the folding bikes like Montague but would love the advice!
Did you borrow the suit, as you left the vent stitching in? 😂
I pointed that out to the spouse! 😂
Brompton is the best bike in the world if you live in appartments or need to commute with a bus or train.......... It really is a worthwhile fantastic investment to have !
Should have gone with the Rohloff rear hub guys! Absolute weapon with that hub
I hope Alex gets the Mechanic rates when doing these videos 🤔🤣 great job Alex
😂😂😂 For the first 5 mins I thought it’s about the security doors
You are able to buy Eastern, Brompton-like parts also from titanium and a fork and triangle intended for a Disc Brake. I would definitely prefer a "Hydraulic Disc Brake" in front, and not waste my time and money for the back, as it is easily able to block the wheel at any time, with the ordinary brake!
My now much less than 2019 SuperlightM6LXBrompton for now weighs 8,5 kilo (mudguards), and still falling, with a little more work on my mudguards, mostly!
Finn. Denmark
007 James Brompton? LOVE THE BUILD! What are the parts and what did they cost? I personally would still keep it as a road bike with less knobbly tyres but the wheel size and choice of gearing and brakes looks great to me.
If Brompton built one at a fair price I'd buy it. Tough folder. Nice.
James Bond / Mission Impossible….Mr Alejandro Bond, Master Bike Mechanic….lol….awesome, super funny video 😂👍💪
Any chance you'll publish a parts list? I'm particularly interested in the front fork and rear triangle you used. There's a million no-name clones and a few places with a web presence, but no clue what's worth money.
They would’ve likely used a Kinetics kit that is Glasgow based. They are the best for after part Bromptons
@@ebenn Yep, Ben from Kinetics confirmed that on Twitter
yeah i dont know why they went through such an effort not to mention kinetics lol even calling his colleague the brains behind the build 🙄
Lol whats the gearing on that thing? Love seeing builds on the channel!
Why not a Rohloff?... With a Gates carbon belt drive...
There are rumours that Alex will be the new James Bond in the next movie
And, riding the Laverack Aston Martin .1R
@@Phillip-hq1bv no this is wrong info. He'll ride off road Brompton which converts into a standard Brompton with the press of a button.
Iu make a video about doing tricks on a bromoton? I've noticed brompton content on your channels (gravel bike conversion here, uphill racing, commuting, ect.) But what about tricks? Is it possible to do a wheelie, manual, bunny hop, etc?
I would love to compare with my Bike Friday all packa, long live 20” mini monster bikes
7:03 Nothing a 600mm jumbo zip tie can't solve :-)
With hub gears, you could go for a belt drive system for lower maintenance and cleanliness.
Thought I was watching a Christian Bale action movie. It was bettah!!!
Even the Batman doesn't have one of these bad boys 👀
Did you return the jacket back to the shop after shooting or why was the "tail" of the suit still stiched together? The two X stiches on either side are still clearly visible.
What brand is the aftermarket parts ? The triangle fork wheels ?
ALL HAIL MOUNTAIN BROMPTON!!
How about the same build with a Veer belt and "normal" tires (32mm)?
If you need an Off Road folder, buy an American Montegue, Army folding bike, also made in a Civil version with many gears, as an ordinary MTB-
the X on the back flap of the suite jacket must be remove :P
No keycard for the lift? What about access security?
Bromptons are almost always a bad idea. That's also what makes them fun
what kinds of fork and rear do you use?
Where can I buy?
be interested to see what it rides like with some 20" Schwable Big Apples and a wider bar
DAMN!! I've seen less doors in high-security prison!! 😝
I want one.
7:11 Change it into a QR pedal.. it will be foldable.. or is it? and don't forget about the magnet clip..
"I'm going to call that a success" *proceeds to fall apart in his hands*
I want one
Where can I get one of doze from 😉
I love this bike. Unfortunately i think where i live, riding this bike would probably get me killed
1:52 your welcome
Greetings from your Birdy :)
The standard 520mm bars will be too narrow and make the ride twitchy. You’d be better to fit Joseph Kuosac mid-rise bars, they’re 600mm wide and have a 100mm rise, SJS Cycles stock them. I run them on my 2012 Brompton H6R, trimmed to 560mm and they handle much better than the stock item.
That's a myth. I have a TERN VERGE X18. It's the only folding road bike ever made. An amazing bike. And the handle bars are narrow. And there's no twitch. But I can slip through traffic others would have to stop for. With 560mm or wider bars.
the names brom...custom brom!
A bike project doesn’t have to make sense. Would love a gravel foldie. There are many others in the market. Brompton was never interested in making it gravel worthy. It’s a boutique bike in Indonesia.
What's the bottom bracket height?
Could have tried or compared a Moulton xtb for comparison
How much was all the kit?
I had ordered a kit from him. I do not recommend these parts. I was really exited about that, but the quality was terrible, and the communication even worst. The Brompton parts I had ordered came extremely late. He said 2-3 weeks lead time, but I only got it after 2.5 months, without an apology or anything. I got an incomplete order anyway, but he did not really cared about that, he did not send the forgotten part after the fact. The paint job on the parts were terrible, really, it flaked down under every screw, it is full of scratches now. He said he did not do the paint job himself. And that is all, it feels like he do not care about customers. The parts are expensive, but the quality is not good at all. My rear triangle was even skewed in the mounting consoles. I was expecting a quality hand made product with a personal touch, but I did not get that at all. (The picture is just for an example, it flaked down everywhere...)
I looks like Harry was REALLY eager to finish this video.
Hmmm, I can see where this is going. Next up
-GRompton (is already 1x...)
-TTrompton
OOH, I sees what you did with the opening sequence! "Missed it by t h a t much"
[thinks...] Oh Dang! Manon as 99 😍 😉😉
The thing is it cost a lot of money to build an off-road Brompton with disc brake. The total cost would be around 5K USD with all the aftermarket parts. I don't know if that's a good idea.
Does your secondary school chemistry teacher know you took those glasses?
The Moulton ATB/APB was designed for this but I suspect small wheels and stump jumping mountain biking don’t mix. Gravel yes.
as long as the hills don't kill your momentum, a 20" bmx takes some stopping!
Quite right. I’m traveling with a Moulton XTB and it’s great for mediocre pavement and well-packed gravel, but as you surmised, not mud, ruts, hopping, or steep ascents where standing on the pedals is needed. With up-spec’d components it is shaping up nicely, though.
You were only supposed to blow the bloody doors off....smoke clears....monster brompton remains.
Bigger tires are better on the street, too, less prone to flats and a larger footprint. Nice work, Alex, except for marking up the frame with a marker, yikes. I'd be mighty disappointed by that, hopefully it'll wipe off easily enough.
And was it only £3,000 for this dream bike? You can get a decent Ford Fiesta for the same money 😂
Custom paint is a worthwhile investment… it doesn’t matter how good your bike is if you’re unhappy with how it looks your not going to ride it
It shure is chunky. Looks are up. Portability is down.
Did Alex borrow his Dad’s jacket and shirt for this one?
Now you need to ask Sam Pilgrim to shred it.
No suspension fork 😝
Alex is Si’s minion? James Bond or James Bond villain?
I'd rather get a Bike Friday, but wouldn't ind taking this for a spin and possibly being proven wrong.
Yes, Yes, Yes. More Brompton, More Brompton Mod.
Brompton CX?
better to just buy a birdy and have a separate Brompton for urban use
As you have gained so many names in the last year, you may add "Q" to the list.
You could have bought a complete brompton clone with 20 inch wheels.
4x rather than 2x too expensive for what it is ..!
and nothing like enough lateral fore n aft stiffness required for the job
Honestly, why a special Off-Road model? It's a "bring for minor use" transport bike for the City and the small wheels are already there, hopeless and much too heavy rolling! Andrew Ritchie should have been severely punished for adding it to every day life!
I own a 2019, now more/less than SuperlightM6LXBrompton, with Mudguards of course, as a Dane, and presently weighing 8,5 kilo, and it is horrible excuse for a "bike".
And already Off-Road also, as I'm easily able to take it up several stairs from that! 😄 Finn. Denmark
No!!! Why??!! 😅
I dont understand the point of this it was already a bicycle after all this effort its still a bicycle, once I made an umbrella from a Brompton this deserves a Mac Gyver award.
Entertainment
Give it to a bmx rider and see how long the frame will stand up to it.
My guess: a donkey will never be a horse,no matter how fancy you dress it.
Leave the Brompton alone, let it just be a fairly good folding bike.
Didn't you even show me how to ride this bike??
No reason to screw what Brampton's designers and engineers did so well...
name is Bond, James Bondmpton...
one more change ... drop bars and pure gravel commuter dream bike... just saying Imagine this machine loaded on bags to travel '*ligth'* awesome rigth?
Next, add 3kW mid drive, w/1kWhr battery.
