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

[@gcntech]

Who would build an off road Brompton? 🤘

[@ShadLife]

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.

[@codak29]

The Brompton folds to enable multimodal transit. Who is taking a train to the trail? IMO it's just a less effective mountain bike.

[@barryhale9364]

You need off road wheels and tyres to cope with the roads around Bath tbf. Reminds me a bit of the Cannondale Hooligan.

[@traderz13]

What was the final weight? My Brompton Bicep is already at its limits.

[@dugldoo]

Alex, how much would the Brompton cost to begin with, and then the rebuild, if someone were crazy enough to follow your example?

[@noze02]

Nice!! Looking forward to the review video. I am surprised you did not mention where the kit come from (Kinetics)

[@andrewmcalister3462]

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

[@jonathanleach3914]

Excellent. I have a “normal “ Brompton with an 11 speed Alfine hub. Really good hub although adds weight. The kit from Kinetic is brilliant

[@gcntech]

An 11 speed Brompton would seem to be impossible to stop 🙌

[@mazingerz99]

Looking forward to this vs Brompton G.

[@davidpomerantz]

It used to be the GCN Brompton. Now it's the GMBN Brompton

[@gcntech]

Started from the bottom now we here ....

[@imilic8]

@gcntech started from the *Brompton

[@K1989L]

That's Kinetics rearframe and fork from scotland!

[@sierrapolo]

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.

[@gcntech]

The power of a good edit 😉 Great to hear you enjoyed the video - enough to make you want to try an off road Brompton?

[@sierrapolo]

@@gcntech let’s not get carried away

[@cb6866]

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

[@jonathanzappala]

It turns out GCN mega base wasn’t a joke, Alex is just describing it.

[@gcntech]

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 👀

[@haolinchen8982]

brompton has carefully look your video, and now come out G line😂🎉

[@byondhorizon3576]

That's what I m going to say! 😂

[@tomcruz3774]

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.

[@gcntech]

Ooooof sounds super bling! Brompton crit racing anyone? 💨

[@WisteriaBerlitz]

Some Singaporeans are getting custom Titanium ones from Taiwan instead of the T-Line My mechanic went with 20" disc brakes and Shimano Ultegra

[@PoulHansenDK]

Get a Bike Friday All-Packa, no mods needed, and all parts are standard not generic. AND it folds ;-)

[@gcntech]

Interesting! Does it still fold? 👀

[@graemeblundell2884]

Yep, like it. Doing a (re)build such as this is what bike life is about. Have fun with it.

[@gcntech]

Bikes are made to be fun, no more so than the humble Brompton 🙌

[@MattButlerAL]

How many damn security doors does one need to go through?!?!?!?!?!

[@jani724]

Right? I'm intrigued by the gcn mega base tour

[@okantichrist]

And the fire escape?

[@nateisright]

How very Maxwell Smart of you.

[@bulletprufrodo]

​@@nateisrightWe're just missing the fall into the phone booth at the end.

[@gcntech]

Shhhh 🤫 You saw nothing 🕵

[@KHSong-z4z]

I've a Brompton but it's just not practical for rough roads, so I bought a Reach GT folding bike for that

[@10415153]

10 out of 10 for that intro GCN team 😂

[@gcntech]

Shucks ... you're making us blush 😳

[@TheBromptonGuy]

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.

[@caspervanosch8654]

I was about to say, this looks mighty familiar!! Just not so in detail as you presented it but probably with a bigger budget on the video production. But did they buy it as a “ready 4 build kit”?

[@andyfairchild2383]

C’mon guys, you might have at least mentioned Ben at Kinetics. You know the guy who made the kit you just fitted?

[@matthewbaynham6286]

Alex needs to join a trade union, Alex is doing all the work whilst Si is just going to have all the fun.

[@hangkook]

Nice set up! It will be interesting to see GCN does a head on challenge of a Brompton P or T Line Explore 12 speed against a road bike. The first of its kind challenge.

[@WalterDill-d9j]

Well done, Major Boothroyd!

[@TimothyDevinney]

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!

[@Vegan_Touring_Cyclist]

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...)

[@LuciferMorningstar666-e1s]

did you return it n get u money back?

[@Vegan_Touring_Cyclist]

@@LuciferMorningstar666-e1s He just blocked me on every platform... So no...

[@LuciferMorningstar666-e1s]

@@Vegan_Touring_Cyclist sue him pls report it to the authorities

[@finncarlbomholtsrensen1188]

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

[@finncarlbomholtsrensen1188]

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!

[@michaelfreeman5933]

Should have gone with the Rohloff rear hub guys! Absolute weapon with that hub

[@TheSpaceBrosShow]

niceeeee! Always wished the Bromptons came with discs

[@hoser7706]

Sweet! You skinny hosts inspire me to ride. I want to see that bike made and sold by Brompton!! CAF!!!

[@fensterputzernuernberg]

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 !

[@playandteach]

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.

[@faridjabb9447]

Wow! Nice!

[@martylawson1638]

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.

[@ebenn]

They would’ve likely used a Kinetics kit that is Glasgow based. They are the best for after part Bromptons

[@ambrosenuk]

@@ebenn Yep, Ben from Kinetics confirmed that on Twitter

[@doooofus]

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 🙄

[@weltanschauungen]

Did you borrow the suit, as you left the vent stitching in? 😂

[@mommamooney]

I pointed that out to the spouse! 😂

[@johnstrac]

Nice one again Adrian.

[@RichardMigneron]

This is more secure than MI-6... James would be jealous

[@andrewblakesley4202]

If Brompton built one at a fair price I'd buy it. Tough folder. Nice.

[@RobWhittlestone]

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.

[@The1trueDave]

7:03 Nothing a 600mm jumbo zip tie can't solve :-)

[@a1white]

With hub gears, you could go for a belt drive system for lower maintenance and cleanliness.

[@joegamas1194]

James Bond / Mission Impossible….Mr Alejandro Bond, Master Bike Mechanic….lol….awesome, super funny video 😂👍💪

[@kendrewreviews]

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?

[@sjanzeir]

Did you mate those short-pull TRP Spyres to long-pull brake levers? 😳

[@slowwerthensnot]

I would love to compare with my Bike Friday all packa, long live 20” mini monster bikes

[@kaupo80]

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.

[@Group51]

The Moulton ATB/APB was designed for this but I suspect small wheels and stump jumping mountain biking don’t mix. Gravel yes.

[@chrisdavidson911]

as long as the hills don't kill your momentum, a 20" bmx takes some stopping!

[@ericpmoss]

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.

[@kwhatten]

How about the same build with a Veer belt and "normal" tires (32mm)?

[@jascollinscork]

I hope Alex gets the Mechanic rates when doing these videos 🤔🤣 great job Alex

[@dangermouseanpenfold]

be interested to see what it rides like with some 20" Schwable Big Apples and a wider bar

[@platypushatstand]

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.

[@fender1000100]

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.

[@epiworks]

What brand is the aftermarket parts ? The triangle fork wheels ?

[@jani724]

Lol whats the gearing on that thing? Love seeing builds on the channel!

[@finncarlbomholtsrensen1188]

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-

[@Shaftalooooo]

😂😂😂 For the first 5 mins I thought it’s about the security doors

[@jedlee7075]

what kinds of fork and rear do you use? Where can I buy?

[@aihsanasl]

@@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.

[@charles0414]

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.

[@davidpala7882]

Why not a Rohloff?... With a Gates carbon belt drive...

[@yvescolin6169]

Maybe because it would add 1000€ (or so) to the bill?

[@dodoogiirawan]

7:11 Change it into a QR pedal.. it will be foldable.. or is it? and don't forget about the magnet clip..

I love this bike. Unfortunately i think where i live, riding this bike would probably get me killed

[@sabaffira]

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.

[@robbchastain3036]

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.

MIBrompton

[@ernestpang]

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.

[@JustMikeH]

I'd rather get a Bike Friday, but wouldn't ind taking this for a spin and possibly being proven wrong.

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.

[@finncarlbomholtsrensen1188]

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
