Great build, love your balance of cost/weight. No surprise that some bits took some fettling to get perfect, but a build like this is all about the tinkering.
Thank you! Yes, it’s all part of the experience/fun for me but I can see how that can be worrying for others. There’s definitely some parts that are quite straight forward to fit as well so people shouldn’t be turned off completely on cheaper parts!
Thank you! At this point it’s literally just two Brompton parts and I might change out the derailleur so that just leaves the rear wheel. The mismatched braking system seems kind of weird way to build a bike but it’s worked great in this context! If you don’t mind a slight wider fold, there are some 100mm wide forks that can accommodate a safer mounting position for the calipers as well. It’s actually a relatively easy mod for those who want some additional braking performance.
Thanks for sharing. Your production skills are as good as your 3D fabbing 😁 I'm suffering from a less than ideal gear range, even with the 5 speed mod. So it's shrewd you went with a practical hub+ system, and then scrimped on weight elsewhere. Also great to see you are hammering this thing up and down the country, like it should be used.
Haha thank you I guess all the hours watching UA-cam have rubbed off a bit. And yeah I think with the smaller wheels and limited number of sprockets the IGH is still a good choice for the Brompton. A front derailleur with dual chainring and a 5 speed rear could work too. Or if you just need a granny heat just in case you can opt out of a front derailleur and just do a manual shift by hand/foot when you need the low gears. And thanks some of the footage was from a bikepacking trip in the Peak District. It was great! I think I’ll make a video about it as well.
Great build, all the DIY is really cool! I bit the bullet and got myself a T-line, but after adding continental contact urbans, ergon grips and taller bars it's at 8.9kg, ouch!
Haha yes those ergon grips are surprisingly heavy especially the ones with multiple hand positions! Which handlebar did you change to? I heard there’s not that many 31.8mm options available that are taller than the M ones from Bromption themselves.
@VelocityPrintworks Yeah I just couldn't find any decent 31.8 handlebars so I just used a shim. They are aceoffix 170mm, tallest that can fit! Super flexy, but I think it's good to move unload flex from the stem unto the handlebars. I might get your Grips! Although I don't need those little nubs haha.
I’m surprised that Joseph Kuosac or one of those guys haven’t made one yet! And I can modify the grips to not have the nubs! I see you’re in Japan, I’ll be visiting in April/May with this bike, hope to get some longer rides in the Kansai region!
@VelocityPrintworks Sweet! I think we talked about it before on Facebook actually haha. I'm in the Netherlands for now but I'll go back in March! I saw Joseph Kuosac has some ergonomic Grips but it's impossible to find the weight anywhere online.
@@KokoroKompassah right i remember now! Whoops, I meant that JK should have made a taller bar with the 31.8mm diameter by now. They make so many other bars haha
I’m not sure if it’s possible with 16” wheels. With lower tyre pressure I think the tyres would deform too much on tough roads with the small wheels and cause the tyres to unseat. Not like there are even 16” tubeless ready tyres and I’m too chicken too try haha
@@VelocityPrintworks There's always a 50% chance that it can work. Such deformation require an ultra low, unusuable pressure, it's very unlikely to happen. Non tubeless ready parts can work tubeless. Ofc it's not garantee to work flawlessly but worth a try for the benefits.
16"?? Tag me or make a most about it when you test it out. I'm pretty much following all the Brompton communities 😂 Very curious about the wheel/tyre combination!
the issue with the dub axle aren't only the undersized bearings, but that the thicker axle is usually aluminium alloy. any sort of misalignment will lead to the bearing inner races eating into the axle. could end up being a non-issue in your case if the bottom bracket shell is perfectly aligned, but this is why i always tell people simple shimano xt/ultegra is techically superior to all these 1000+ euro sets from boutique brands. your bike is very nice. i have a standard 2 speed s2l, it's 10 kilos without mudguards or rack but with the front block and kojak tyres. the only part i changed is the saddle. i also like the name brompnot
I see, I get what you mean, the SRAM DUB standard uses a thicker axle so they can use a lighter alloy for the axle, presumably a lighter material for the 24mm axle standard would lack the necessary stiffness or strength. Good point though, I don't see the durability aspect of these axles raised often! 10kg is not bad for the standard 2 speed! The bike I showed at the end was my wife's superlight 2 speed with a lot of mods and its around 8.5kg and she still complains its too heavy to carry haha
Damn bro people building bikes from scratch on top of that something ugly like this, but I get it you get exactly what you wanted.. i am amazed how you go about measuring the weight of every single part I'm not a bike guy I just have E-bike (which I didn't build by my self from scratch btw.) but since its my daily driver I have to know how to take care of it, and that's how your video ended up in my recommended I guess
Haha yes there is a whole subculture of weirdos like me that weigh everything! I never considered the Brompton ugly or beautiful, just a great portable form factor. But yeah you really have to ride and live with a Brompton to appreciate it and even then it’s not for everyone especially if your priority is comfort and speed
Very unique build, but technically it's not a Brompton anymore. I too own a heavily modified Brompton with the frame and brakes being the only things original. I agree the Brompton stock brakes are best. The 2nd best are the Paul Brompton brakes.
Commenting for the algorithm 🫡

Very Nice! Great idea to mix the brakes up. And it seems you smartly chose brompton parts, where it made sense. Also +1 on zipties

Well done Ed :) I like your editing style!
Thanks! And thanks for the park tool scale haha, finally got the "official weight" so no more excuses for procrastinating on the video!
@@VelocityPrintworks haha yes! that's a great first video, I got hooked till the end :)

The lack of tubeless is the only thing that holds this bike back from maxing out the brompton platform.

@ you first 😆 for a 20" wider tyre I might try it but 16" is a bit too risky for me.
Tubless is on the way as we speak.
