I Broke my Brompton…. for good?

[@kwhatten]

I did this with a steel bike while in Thailand. Two minutes away from an autobody repair shop. Welder welded it in about 5 minutes, charged me $2, and the repair lasted another 3 years.

[@ibikeunfolded]

I actually thought about welding it. I could borrow a welder as I do have the know how from working on cars for 15 years.😁👍. Good ideas..

[@krob9145]

I recall this happened to my bike when I was a teen and my friend suggested going around the corner to a neighbour who was a welder. We begged for help and he welded the bike back together.

[@serhiirudenko6183]

Came here to say the same. Steel frames are easy to weld, can be repaired at any car repairing shop. Was doing it many times with BMX bikes. Cracked and bent BMX bars MUST be replaced though.

I’m with you brother: my c-line has done thousands and thousands of kilometers for years and I love it. I’ve worn through tubes, tires, bottom brackets, pedals, igh and this week I broke a jk crank arm. I own other 4-speed p-lines, but still ride my 6-speed c-line every day. I ordered a 12-speed yesterday but am torn on repairing my origial c-line or moving on. Anyway, I’ll keep riding brompton.

[@trigs1441]

Sad news about your brompton but i suppose you do give it a good thrashing every time you ride it.The positive to come out of this is that you didn't sustain any injuries except on your bank balance, which can always be replaced. Keep the vids coming.

Thanks, yeah there is always a silver lining…. Just not inside my wallet😄

[@ytfruga]

Hi Brian, you’re probably the most valuable tester of Brompton globally! I guess the London’s engineering team is scratching their heads to figure out how that failure was possible. Formally they’d probably tell you the bike should not be stressed to that extend to be covered by the warranty. However I might count on their gratitude for your honesty in sharing the story. For that I’d suggest you contacting any authorised Brompton dealer in your area and present your broken bike. Sooner you do it more you might gain allowing Brompton to respond in a non-standard way. If I were you I would wait any moment.

[@TheSaxcat]

Not as catastrophic as you might think. It's steel, the easiest of all the bike materials to repair. If I was an ultra-distance adventure rider, I would choose steel because of its ride quality and also because almost any local welder in the world could fix the frame should it crack or break. If you can find a bike builder to help you out, that would be best, but in a jam anybody with a welder will do. Titanium, aluminum, carbon repair requires more specialized skills and know-how, making those types of repair persons more difficult to find and much more costly. This type of repair will cost way less than what you might think. Good luck with whatever decision you make moving forward.

[@ibikeunfolded]

I will probably replace the triangle at a later date…. Right now I am going to get a new Brompton for my bicycle tour..

[@凸Bebo凸]

I hate carbon bikes, but you don't even need a jig or any specialist tools to fix a carbon frame. It's just a bunch of resin, carbon sheets and patience. Easiest frame material to fix by far.

[@mad2barxhst]

Another analogy is touring on a bike with hydraulic disc brakes. I’d much rather travel with cable operated disc brakes. They’re easier to fix.

Yo Brian, love the vids! Your US community might be interested to know that Brompton is huge in Singapore. You can’t take a full size bike on the MRT (train) and just about everyone lives in an apartment so that’s why they are so popular along with other folding brands. I have an Element Troy folding bike made in Indonesia that I am very happy with. It’s rare to see Bromptons getting hammered although some people use them for the triathlon series here and in Malaysia as it’s hard to store a full size bike unless you are hardcore rider (also popular in Singapore), you would be right at home here (when you get used to the heat haha)!

[@tomcurran65]

You can fix that anytime with a new rear triangle, so if it were me, I would take off the triangle, bring it to a welder and get him to weld and brace and strengthen it. You must know someone with a welder who can do that for a few dollars and with a bit of black spray paint you wont even see it. You cannot make it worse so its worth having a go, if it is not right you haven't lost anything (you will still need a triangle). Its a steel bike so it would be a good solid repair. Sure it wont look factory, but it will look modified 👍 . Your bike will be fixed and 100% functional. It will still serve as a winter beater if you don't want to put the money into a new triangle, or have lost a little confidence in its reliability for a tour. Andrew Ritchie (Brompton inventor) did a lot of welding, cutting and welding again of prototypes to achieve the geometry of the tri fold design, the art of brazing came later. I had a mountain bike snap the rear triangle at the axel on the same side, I too was stunned by the failure got out the welder , welded it back together and carried on for another 5 years with that bike. I currently have a 2023 C line 6 speed, best bike I've owned, The weakest part of it is me 😄

Everything breaks. Eventually. Good to see the failure, sort-of-catastrophic as it was, allowed for a controlled stop and no injuries. Which is about about the most one can hope for in this case. Betcha that crack was propagating for a long time before you noticed it.

[@gregsimmons1709]

Good philosophical perspective on the damage! Another C-Line makes a lot of sense for what you’re doing. I upgraded to a 4-speed P-Line after the theft of my C-Line. I absolutely love it but it is not simply a lighter C-Line. The titanium forks and rear triangle, and overall lower weight, provide a very different riding experience. It is amazing in urban/city riding, it is considerably more nimble and responsive than the C-Line, but it is also more demanding and less ‘cruisey’. These differences are, of course, the point in having different models in the product line… If I had the money I would have one of each. I’d have the P-Line for the fun and excitement it brings to my daily commute and also for my short multi-mode tours that require a lot of folding and carrying on and off overnight trains. The C-Line would be for the ‘heavy lifting’ bike packing stuff.

[@ed0078]

Time to ride the Chapter 3 as your daily commuter.

[@ibikeunfolded]

You maybe right😳

[@mad2barxhst]

I had two of the Chapter 3. Nice bike. I eventually got rid of them. Too expensive for the name and accessories used. I had to change the seat and handlebar grips for better comfort. In hindsight it is better off to get the P-Line, which is essentially the same bike minus the added advertising name. Additionally, the Chapter 3 has a noticeably heavier rear end compared with the P-Line because of the Sturmey Archer rear hub. There is some sacrifice in the gearing ratio with the P-Line but I’m okay with it for my riding style.

I have the poor man’s Brompton, the Dahon Classic iii with a 2 speed kickshift rear hub with a coaster brake, it’s an old bike from the late 80’s but it’s probably one of the most bulletproof bikes i’ve used, if you’re just riding along and the frame just snaps going over a speedbump that’s definitely not something you want to be buying.

[@凸Bebo凸]

You kinda have to buy Reynolds 725 or better steel nowadays or this happens. The air hardened steel welds become much stronger when welded, standard Cro Moly doesn't, and they use the least skilled welder on the team to do the standard CroMoly frames nowadays, unlucky. Couple years back I snapped the bottom bracket right off a Surly Steamroller in about 3 years, couldn't believe it.

Thanks so much. I'm a super heavy cyclists and thought about getting a used Brompton for travel but I'm sure it will fail on me. Sadly Brompton doesn't want to make a high load version.

In case the info is helpful, I ride a C-Line almost every day and I’m ~105kg and I use a kid seat with my son who is ~16kg… and once a week I do shopping with loaded front and rear bags (not near the 10kg limit though). I do ride gently when it’s very overloaded like that, but the bike handles it like a champ, so Brompton are being (rightly) very conservative with their stated limits.

[@FuchsHorst]

@@henryjtodd It might be a quality issue or a difference of build year and type. I know many die-hard users that use their Brommie for hard action but I also know casual overweight riders around 100-120kg with frame damages. They rode only on pavement within city limits. I'm way above that weight and ride steel frames myself. 0 defects. But I don't want to push my luck, especially because Bromptons are also very expensive. Not want to waste several thousand Euro in case of denied warranty.

@@Bikesdavebikes Thank you - I wasn't criticising or questioning anything you said. It does make sense. I just try to find where communiting ends and touring starts. You can haul groceries or maybe a larger person. Also bumpy roads exist. I believe the horizontal stress is a factor which happens off road and that happens more often on touring. We do have a few cobble stone roads in germany and eastern europe, but I suppose if you'd have one on your daily commute you wouldn't use a brompton. It's no fun.

[@mad2barxhst]

The Brompton bike frame design is not the best for loaded touring. A long seat post of continuous wall thickness coupled with a heavy top weight is a recipe for disaster. The seat tube needs to have an internal tapered wall where the tube is thicker at or near where it comes out of the seat tube. There is a lot of stress where the seat post exits the seats tube. The small diameter tubing in the rear triangle would see a lot more stress specially at welded joints. It’s better to go bigger diameter at welded joints or use butted tubing to spread the stress loading over a larger area. Perhaps, Brompton never intended to design/build the bike for any kind of loaded touring or stump jumping.

[@vincentnnyc]

I’m doing the same….i’m gonna ride my brompton to the ground and get a new one if it ever breaks on me and cost about the same of fixing it vs buying a brand new one.

[@ibikeunfolded]

I agree wholeheartedly 😁👍

[@somethingforsydney9862]

Brian, you are the best brompton rider ever.

[@ibikeunfolded]

Thank you…. I don’t think so, but thank you…😊

[@antonolan]

Use your Warranty!!!!!!!

[@KG-theknickerbockerkid]

unfortunate but looks like you squeezed every ounce of performance from the bike. do you track how many miles you have ridden? what is the typical lifespan of a bike?

[@Zen_Not_Zen]

Noooooooooo! Funds allowing will you get a new 12 speed ? Maybe @bromptonbicycle R&D should know about this?

[@Jeekheang]

Is your bike covered by the 7 years frame warranty?

[@ibikeunfolded]

I don’t know? Maybe it’s something to look into.. I bought it 4 years ago..

[@marlondelgado9751]

​@@ibikeunfoldedgo to to shop where you buy your brompton, it may help you there to claim your warranty.

[@goopie12-ot4so]

@@ibikeunfolded When I bought my C line, it was from a shop, and the registration happened more or less automatically. I gave them my email address at checkout and I have the certificate somewhere. Even if you don't have a receipt/certificate, check with the store you bought it from. I am sure they wouldn't want to disappoint their brand's biggest KZbin fan :)

[@ziggarillo]

​@ibikeunfolded I'm sure if they look at your channel they will.

[@steelerman7862]

Check out the warranty Bryan. When you bought yours the warranty was for 5 years, 7 years once you registered it. Just like the new ones. Do you still ride your CHPT3? Or is that just a beautiful sculpture you admire occasionally?

[@antonolan]

Warranty!!!!

[@ibikeunfolded]

Hopefully…hopefully😁👍

[@bredemeijer9648]

Buy a P line 4 speed and get a double chainring. 12 speed is heavy and for mathematicians. 😉 Sorry to see it break on you.

[@Cliff-lp8lj]

Have you had it for less than 7 years? It may be covered by the frame warranty.

[@atrobertootto]

😮😮😮😮😮😮😮

[@sogeking9395]

I would really like to know the model or part number on those Scvcn shades.

[@ibikeunfolded]

I actually bought those off Amazon. You see I loose shades and I refuse to spend 200$ on a pair of Oakley’s or some other expensive brand…here is the link.. www.amazon.com/gp/aw/d/B0CP7R4FK1/ref=yo_ii_img?ie=UTF8&psc=1

[@sogeking9395]

Perfect! I agree with you I would rather have a drawer full of 15 to $30 frames. I made the mistake of buying an expensive pair of oakleys once and an expensive pair of Wiley X once and was involved in a bike accident and a kayak accident. I'm okay before $400 worth of glasses or either crushed or floating at the bottom of a river

[@philippcausd]

if the warranty won't be successfull I would weld it for few Dollars

[@ibikeunfolded]

Hopefully I can get it replaced under warranty….hopefully 🙏🤞

[@ThitiMakornkhan]

I Hope your Brampton get covered by warranty.

[@ibikeunfolded]

That would be nice😁

[@jackhorsley3912]

Just get it welded or get a new rear triangle no biggie

[@Garfie1d73]

Brompton bikes are cheap crap sold at a premium price. I will never fall for them. A happy Birdy customer (for more than 2 decades).

[@artofhookie]

Bikes that never get ridden last forever :)

[@YLSG]

Brompton has a 7 year frame warranty

[@ibikeunfolded]

I know! That’s what everyone is saying. I hope I can get the triangle replaced under warranty. 🙏🤞😁

[@BrownPeterAnthony]

Dude, take it to an engineer and he will patch it stronger than new for £20, that why a steel bikes is better than ali.

[@ibikeunfolded]

It’s an excuse to not a new Brompton. I will fix sometime in the future👍😁

[@rewe2424]

New rear triangle time. No biggie.

[@ibikeunfolded]

Hopefully I can get it under warranty🤞
