Brompton 2004 M3R Rebuild

- I recently bought a 2nd hand 2016 Brompton S1L and plan to slowly convert it into a Semi-Black Edition. The plan is to buy another used Brompton to received all the components that will be replaced from the S1L. But the plan went into a different direction which happened along the process. The M3R even though bought with a good price and running is really in a bad condition so I decided to just stripped it down and rebuild it. It is a good way to spend time also learning the bike mechanics. I had fun doing it and although the finish is not as good as a Raw Lacquer Model as expected from an amateur like me. I think it turns out well! Please enjoy the video! Thanks!
Brompton M3R = 400 euros
New Components = ~175 euros
Extras = ~100 euros
Old Components, sold for = ~20 euros

Absolutely Stunning! Is priceless now!
A m a z i n g ! !
The raw metal ... the component selection 👌.
Just superb!!
Just one thing... be careful with the aluminium frame clamps!
They have a tendency to break mid ride!
The rest is as I said... superb!
Thanks! I'll keep an eye on that part!
You have got yourself a "unique" Brompton ! Great work !
Thanks! I tried to keep it as original as possible but I got tempted with the gold parts! Total cost is still around 600 euros!
Man, this is sooo cool. You should meet Vincent van Eerd in Amersfoort. He also does magic with Bromptons, derailleur, wheel sizes etc. Hats off for your rebuild!
Hey Bas! Yeah, I had fun disassembling and rebuidilng it. I had looked for the cheapest Brompton I can get from Marktplaats for the project. I also met nice Dutch guys who did the Glass Bead Blasting to expose the steel.
Galing mo man😎💪🤘 now ko lang nakita😂
Gorgeous! Where I am at over in the US bromptons are rather rare so I'm actually buying a new black lacquer because raw Laquer is no longer available
Thanks for the lovely video! Nice to watch and the bike turned out really nice too!
Excellent restoration job - that bike is truly a thing of beauty!
Really awesome! You must be proud 👏🏼👏🏼👏🏼👍🏼👍🏼👍🏼👍🏼👍🏼
Thanks, and yes I am, I tried to avoid spending too much on fancy components.
Gerçekten harikaydı. Ben de iki tane eski Brompton satın aldım. Onları bu şekilde restore etmeyi planlıyorum. İyi bir örnek oldunuz.
Looks awesome
That is a very beautiful bicycle! Well done. Thanks for the lovely video. Enjoy it!
Very nicely done, it looks exceptionally good!
I've always loved the look of the original handlebar and bought myself a titanium version and the original Brompton handlebar support brace to go with it.
Have you considered the Eerder-Metal Frame Hugget Utility Platform Mk6, a beautiful piece of kit!
Awesome project and video ! Enjoy your ride.
I'm considering buying one as well. It's good to know that they are built to last.
It's a really handy bike and the space it consume for storing is so small. Really great for city living like here in Rotterdam.
@@brompterdam thanks for your reply.
I was considering buying a Brompton to visit some European cities and taking it on the plane or train.
@@infra6939 ah, that will be very handy! I also use this a lot for travel to work because it is free on trains here in the Netherlands. I did try bike packing with it. It is fun although slow! 😅
What an awesome video. Love it so much. Thanks for sharing.
Beautiful.
Nicely done 👍🚲
Amazing, looks fantastic, love the bare metal finish. Thinking of doing something similar to one of my Brompton's, I am wondering how many hours it took, great job.
Hi, sorry for the late response! I did no manage to track actually the exact hours but as I remember, it took me 2 weeks using my free time or after work.
Nice job. Great video.
Great job! Thank you for this video!
First of all people are interested - what price?
I believed I ended up with a total of 600 euros but I had fun doing it! Cheers!
Supermooi. Ik heb ook de raw lacquer en heb den brinker gevraagd, maar ze hebben me doorgestuurd naar Rotterdam Coatings omdat ze niet coaten. Dat is voor mij net iets te spannend om dat zelf te doen. Heb jij iets van instructies over het zandstralen en de blanke coating die je hebt gebruikt? Alvast dank…!
absolute perfection!!!!
Great job
thanks! I appreciate you comment!
Have you found that since you made this film that rust has reappeared on the frame?
Hello! Unfortunately, yes. It is like tiny rust color dust inside the paint in the areas that the paint application is thinner.
Beautiful!
Thanks! I am planning to rebuild another one!
Nice stuff mate. So - you kept the Brompton calipers and just changed the levers? If so did you have to renew with new cabling? I only ask as I have 3 Bromptons but only one with the post-2012 levers and would like to change the other 2 bikes but only if not to expensive.....
Hi! Yes, I kept the Old Calipers. I renewed the cabling using standard ones and cut it my self according to required lengths.
Ziet er super goed uit! I have some questions:
1. Can the rear triangle axle (in the pivot point of the rear axle, not the rear wheel axle) be easily removed and reused?
2. How did you clean and prepare the rear rack? I'd like to remove the oxidation of my alu rear rack but not sure if it will look good, I noticed you painted yours.
3. Do you have any tips on making sure the spray paint reaches all sides of the frame and fork folding hinge?
Hi! Sorry for the late response! The rear axle is a hassle to removed without the tools. I ended up buying the specific tools in an online shop from Belgium called Vlerick Fietsen. The Rear Rack is cleaned by paint remover and sandpaper and I painted it up because the color already faded. Light Glass Bead Blasting would help I think instead of stripping it yourself.
@@brompterdam Thanks! I completed my full rebuild :) I ended up removing the rear axle, damaging the thread in the process and then replaced it. I used sand paper and a metal file to clean the rear rack and then used a silver spray paint that's suitable for bare aluminium (a paint suitable for galvanised metals).
Nice work. I am looking forward to Do the same thing in the futur.
I have a question about the front joint.
Did you open in for blasting and paint or did your leave it togehter ?
Nice and good luck in your project! I kept the Hinge in the main frame as well as the Steerer intact but I do remove the Rear Frame.
@@brompterdam Hello and thank you for the quick answer.
Nice color of bike . Is that grey or silver ? Thanks for sharing . God bless .
Old component looks new just by soaking in vinegar?
Yes, but there is a downside on the plated ones, vinegar also removed the plating and turned the bolts into matte gray finish almost look like titanium. These are the bolts on the wheels.
Wow. 😊 thanks for that information.
Wow
Was it easy finding all the components to buy? Would it be possible to build one from scratch? Where/what website did you use to buy all the parts? Thanks!!
Hello, yes it is. I live here in the Netherlands and in a country full of bikes, Brompton components are everywhere.
Hey how did you paint it? Did you do it by yourself?
Thank you
Yes I did. I used a standard Clear Acrylic Spray Paint.
Nice finish. Can I ask: what spray did you use? Looking to do something similar. Did you use a transparent primer?
Hi! The paint I used is MOTIP 1K CLEAR COAT HIGH GLOSS Acryl. I sprayed for about 5 to even 6 layers in a span of 2 days including intervals.
@@brompterdam Thanks for the info! Not worried about rust forming under the clear coat?
Are all brompton frame have this color inside?
Depends on the Paint Stripper used. I tried a liquid ones but did not work well then I ended up with Glass Bead Blasting which if not handle well, will also strip parts of brazing.
@@brompterdam some people will buy that bike 2-3x price of brand new bike.
👍
Hi, how is the corrosion? it is showing up?
Hello! So far so good. Used it under a rain but also wipe the bike clean after arriving at home. I am pretty sure that it will definitely appear at some point. I'll keep an update.
How did you add the brompton logo again? / Hoe heb je het Brompton logo er weer op aangebracht?
👏 nice!
hi Ana, musta? thank you sa comment!
@@brompterdam ok naman. Paampon ulit kami kapag pwede na mamasyal.😂 ganda ng bromptons mo.
Wow Nice work! Great inspiration too! may i ask what colour / exact paint name is this please? grey lacquer? lol
Can be! hahaha! It's the result of the Glass Bead Blasting and I just applied a Clear Lacquer to seal it off!
@@brompterdam cool! 😎 thanks
@@brompterdam Hi are you mean this Blue colours is original from the frame after Glass Bead and spray clear coat?
@@cheewaiyow7469 bead blasting is like sandblasting but a little more controlled usually. They basically strip it down to the parent material. When he got the bike back from them it was completely bare metal. Chromoly Steel tubing and the brazing is the gold stuff. You're not seeing any paint or lacquer or anyting and then he just clear-coated it to seal it so it wouldn't rust
2004? Were there new part incompatibility problems ?
Yes 2004 as per the Serial number and frame number. I did not seem to encounter any compatibility issues. I took some of the components from my 2016 S1L and used it in the 2004 one...
Extreme bicycle porn! I'm somewhat breathless and love the bare metal finish you've achieved. Congratulations 👍🏼
thanks!
Hi, how much you paid for the bike and the whole project? How to paint the joints golden color?
The entire project cost me around 650 euros. The joints are the actual Braze Welding of the bike exposed just like what the Raw Lacquer Version.
@@brompterdam thanks
@@eugenelee1830 I believe it is brazed and not welded.
May i know what is this Blue colour calling please?
Хочу узнать где комплектующие для него приобрести , причем всё
Hi.What is the tittle of your music?thank you
