Latest Modifications Done On My Brompton!

I highly recommend going to Bike 48 once you pick up your new Brompton. Peter is a very knowledgeable guy and will basically run through the essentials of a Stage 1 Brompton upgrade.
Final weight of 10.35kg, it isn’t the lightest but it’s good enough for me!

Aww, I miss Peter from Bike48 so much since he migrated to Australia. The dude really knows his Brompton stuff and dealt with some of the most exotic Brompton mods (Shimano derailleur with electronic shifting!). I spent so much time and money at his shop 😄

[@williamlee1426]

Where can we send our bike to upgrade now? Any suggestions?

[@bungee28]

​@@williamlee1426 There are a couple of shops and *work-from-home chaps who service Bromptons: 808 Cycles, B-Spokes, Happy Owl Cycle, *'kiong.' on Carousell, *TAB by HangTuah. Do also check out Unique Custom Cycles (located near where Bike48 was). It's run by Lewis, a former aerospace engineer. He can weld, machine, fabric parts and offer solutions that other shops simply give up on. Cheers.

[@ibrahimhamid5154]

Thank you Jamie for the video. I've been wanting to buy a new Brompton but its out of stock everywhere. Hope to get one soon and slowly upgrade little by little

[@4791_]

For a 6s, that is light enough. I have a 2s with a P stem and a super low carbon handle bar, also with Ti extremities. Weights about 7.8kg and it's very fast. Replace your saddle with perhaps a Cambium.

[@jamaludinothman6260]

Hi Jamie, I enjoy ur videos a lot. I know this video is 2 yrs ago, and Peter mentioned he powder coat ur silver hub to black to match ur black rim. Any idea if the seal and bearings need to be removed first b4 the powder coating? Thanks in advance?

[@reyskidude]

ive a single speed no rack/mudguards steel brompton around 10.9 kg. can't roll it, no joke to carry in and out of train station, so i try to take bus when i can, more convenient. in this regard, the stock saddle lets you carry it comfortably. best upgrade is the engine - keep riding it, progressively increase your distance, speed, and fitness... then the weight won't matter much anymore

[@jamieohpa]

Fair enough ;) I just installed a new saddle though...lol

[@imranr99]

Brompton's are expensive for what they are. I plan to buy one second hand. Then upgrade it but by bit, until I am happy with it! I will probably upgrade it with lots of titanium too. Nice work Peter! 👍

[@finncarlbomholtsrensen1188]

You may get an axle with an extension, to make it wider and more stable when folded, and also a little higher by that, so the wheels are further away from the suspension, and so avoiding the wear on the block.

[@alfred3083]

Wah!! That’s beautiful!! may I know what’s the rough cost of changing to titanium or your transformation cost?

Hi Peter , I owned a Brompton without front and rear mudguard and realised that when fully folded , the bike will slanted a little to the left (the other side of where the stem is down) and also just fitted the extender bar and also my handlebar touches the ground , is this normal ?? Pls advise

[@cabaretampere]

What suspension block is that?

[@MisterAshbrook]

When working on a brompton, don't clamp it in the workstand by the seatpost. There's too much risk of distorting the tube. Instead, clamp it by the main frame tube. That's what Brompton themselves do.

[@tortinwall]

Are you saying the seat post, which can support a 100kg person over bumps and kerbs, may be distorted by a clamp? I very much doubt it.

[@jimmys6566]

@@tortinwall lateral compression is not an issue w 100kg rider

[@arinpoonpinrode1467]

Have you forget how the seatpost is held in place in the first place? It is clamp by the seatpost clamp, so being clamp by the workstand will not damage the seatpost. Infact on carbon road bikes it is safest to clamp by the seatpost.

[@asap19980]

Which brand are the Rims?

[@slippyg]

Wish I had a torque wrench. They're so darn expensive

[@martin701]

Lots of different opinions but I would tend to go with the ones that say "Why change a perfectly good British made Bike?". Bromptons have been around a long time now and are supposed to be a proven brand. A look at some of the factory vids will demonstrate that. Hand made actually. There is a lot of talk about weight saving, but this isn't a bike meant to help win the TDF! It's basically a commuter bike, so what difference will shaving a bit of weight make? I agree with those that say a good mod is to fit a Brooks saddle. Cambium? Perhaps not, but a good B-17 with a bit of weight, well yes, provided you can suffer a bit for the first 300 miles. I really don't understand why these mods were made, but then I'm not Mr Lim and each to their own!

[@miffachan123]

So true. I agree with you. I have had my brompton for 2 weeks. I dont see any parts to upgrade.

[@philipbarrett3151]

@@miffachan123 I bought a used one & ended up replacing some of the previous owner's "upgrades" with stock parts from Brompton!

[@yongjianyi3556]

Thats pretty expensive! I might get a titanium seatpost because of the rust, in SIngapore everything steel rust

[@williambunting803]

Very interesting. I’m keen on the Brompton but would like suspension in the front so will look at a mod to raise the steering bearing give room for movement and look for options. As a designer I have a design for a very robust 12 speed gearbox (50mm wide and 80mm dia) that is in the pedal hub and that would give the 20” wheel version advanced performance. Its good to see that there are people building specials. You will certainly enjoy your pumped Brompton!

[@TheYucaseca]

What brand/model pedals are you using? Thanks.

[@jamieohpa]

They’re MKS pedals.

[@mikhailman]

The biggest investment i made on my brompton is a Clavicula SE crank with a fiberlite carbon sprocket. Other cyclists hate me for that :) But it helps running around the underground, saves another 200-300g

[@dydanz]

you must be a dentist. I'd prefer CaneCreek EE Wings, no carbon parts (Ti/Alu only) to make it bit stronger to impact/scratch during commuting.

[@mikhailman]

@@dydanz To be honest i've been riding my bike quite hard commuting every day ~8-9 km to work and back, and apart from some scratches (which are ok for carbon) there are absolutely no problems with the crank. It's as smooth as the first day i installed it. Those things are much tougher than they look. And i go full force on them when the light goes green :) It has been almost half a year since i installed them. CaneCreek have some amazing hardware. I've got a set of their mountain bike breaks too. A tiny bit heavier than the carbon analogs but MUCH tougher.

[@uwelancier2316]

It's close to 2 years now: Do you still use your Brompton without any further modifications? If not: why not, and if altered further: what and why? How often do you drive it and for what kinds of distances and roads?

[@jamieohpa]

Yes I still ride it, no further modifications as yet given the COVID situation. I typically put around 20-30km on the Brompton, really short rides where I live...

[@omerfurtun4115]

Why does a folding bike need a Chris King headset and ceramic bottom bracket bearings? Ceramic bearings wear out the metal race since ceramic is harder than steel. Although higher in performance they will wear out quicker. same thing with the headset... Aren't these things meant for commuting (ie. durability in mind). This is like fitting high performance (high maintenance) formula 1 technologies on a Toyota Prius!

[@jamieohpa]

Looks cool 😎

[@omerfurtun4115]

[@shtstirrer]

i find on my bike that dealing with other cars and pedestrians becomes increasingly hazardous when u go above a certain speed .. the upgrades make no sense

[@MrJonathansymes]

It seems like a lot of time, effort and money to modify a perfectly good bike to look and perform in a way that was never intended. The Brompton is in essence a very well designed and put together machine. I would suggest that if you require a bike to go fast then, purchase a road bike. If you want a bike to go long distances, purchase a touring bike and if you want a bike to be rugged, then purchase a mountain bike. The standard range of Brompton models perfectly fit the niche market of folding bikes and to make any modifications is simply failure to understand what the bikes purpose is.

[@Samthemancharles]

J RS Welllll there is some subjective truth to your comments but if we accepted your premise mountain biking would never have developed from the boys in Marin ( or Colorado depending who you prefer). I remember seeing a guy in the 80s riding a road bike with the handlebars upturned, for his comfort, and the bike shop guy commented well that was not what is was designed for (true but irrelevant to the user). I personally won't do this to my brompton but it does give me some ideas. Thanks for the video Jamie Lin and the Rich Crazy Asian perspective :-).

[@slothypunk]

What is the brompton bike purpose? I think I am pretty sure know what is Brompton's purpose for the OP! But for you I don't know since with your explanation, I am pretty sure that most of us shouldn't buy brompton since there are good folders out there that cost way cheaper and still ride and build decently, comparable to brompton's quality

[@finalbattle777]

Hi Jamie, since you ride on the road, I suggest replacing stock Brompton pedals with MKS Ezy detachable pedal system - clipless pedals MM Cube: www.ebay.com/p/NOS-MKS-MM-Cube-Ezy-Removable-Pedals-pair/2124039505 ; flat pedals Promenade to switch around: www.ebay.com/itm/New-MKS-Promenade-EZY-Pedals-Quick-Released-Road-Touring-Black-/401649473344 I use them both, clipless for longer distance, flat for casual rides. MKS’s shoe cleats differ from Shimano’s in shape but will work with SPD shoes as it uses the same 2 screw mounting system.

A bit more flame than needed, but there is a good question as to what was bling and what was performance. If Ti is for corrosion maybe. At $1 a gram, discussing the performance is germane. Before and after weights help. My unmodified S2L is 10.9kg

[@bungee28]

Brompton upgrading is always a weird proposition since you start with a hulking expensive steel bike. Short of the frame and brakes, I've swapped out (and sold off) most of the stock parts, with a goal of bringing the weight down, preventing corrosion, and improving the ride. Some parts like a spring suspension block and more comfortable grips added weight, whereas most others have lightened my bike. Not surprisingly, the total upgrades exceeded the cost of the bike, but that's part of the fun of owning and personalising a Brompton. M2L-X at 7.9kg post-upgrades, including a 3-gear rear sprocket.

[@Wog68]

Unbelievable. First of all, when price of the bike 1500+ Brompton must have used best quality parts. Do we see Brompton in championship race or Olympic? So, why to worry about weight. (Buy carry me by pacific cycle 🤣). If anything in steel or aluminum rust in Singapore then Brompton should make titanium or carbon fiber version of it for singaporeans as it appear to be very popular bike and status symbol or you should buy titanium bike made by somebody else. Finally, whenever I would buy Brompton, I would upgrade it with Rholoff gear hub and as status symbol (if I have tons of money) I would ask Brompton to build it in real gold or platinum. What about installing Tannous tires, so that you don’t have to worry about punctures and belt drive so that you won’t worry about chain. This would make it maintenance free. For commute, install a flag and Air Horne and Son dynamo and supernova lights.

So far I had not seen any Brompton in mrt.99% of Brompton owners in Singapore have a car and most of the time they put it in their car boot. They will tell you it is UK made therefore it is the best!
